Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0031] The embodiment of the present invention provides a filter device connection structure, an air outlet assembly and an air conditioner. The filter device rotates around the shaft while the shaft slides along the guide rail, so that the filter device can stay at any position of the guide rail and rotate to open, making it convenient to clean and replace the filter device.

[0032] Combine the following Figure 1-Figure 4 The technical solution provided by the present invention is described in more detail.

[0033] Embodiment 1

[0034] like Figure 1-Figure 4 As shown, this embodiment provides a filter device connection structure, the filter device can be closed on the air outlet, and the connection structure includes: a guide rail 5 arranged on the side wall of the air outlet, and a shaft 2 arranged on the filter device, and the shaft 2 is movably connected to the guide rail 5; the filter device can slide along the guide rail 5 through the shaft 2 under the action of external force pushing or pulling, and rotate with the shaft 2 as the axis to open the air outlet.

[0035] The filter device of this embodiment includes a frame 1 and a filter screen located on the frame.

[0036] Among them, since the shaft part 2 is movably connected in the guide rail 5, the shaft part 2 can slide along the guide rail 5 under the action of external force, and can rotate in the guide rail 5. Among them, the shaft part 2 slides along the guide rail 5 to stop the filter device at any position of the guide rail 5, and when the filter device is rotated to open, it is convenient for the staff to clean and replace the filter device.

[0037] The above-mentioned air outlet can be a return air outlet or an air inlet on the air conditioner body 9.

[0038] See also Figure 1-Figure 3 As shown, the guide rail 5 in this embodiment is arranged on the inner wall of the return air outlet and is located on the upper and lower sides of the return air outlet. In this case, the filter device can rotate in the vertical plane; alternatively, the guide rail 5 can also be arranged on the left and right sides of the return air outlet. In this case, the filter device can rotate in the horizontal plane, which is not specifically limited here.

[0039] The filter device connection structure of this embodiment is provided with a shaft 2 on the filter device, and a guide rail 5 is provided on the side wall of the air outlet, so that the shaft 2 is movably connected to the guide rail 5. When the filter device is pushed or pulled under the action of an external force, the shaft 2 slides along the guide rail 5 while the filter device rotates with the shaft 2 as the axis, so that the filter device can stay at any position of the guide rail 5 and rotate to open. After the filter device opens the air outlet, the filter device can be cleaned and replaced to prevent dust, cleaning water, etc. on the filter device from entering the air conditioner body 9 to affect the operation of the condenser assembly 10, the compressor, etc., and the filter device stays at any position of the guide rail 5, which is convenient for the staff to operate and is more convenient to use, without the need to disassemble the entire filter device from the body.

[0040] As an optional embodiment, the shaft portion 2 is located on one side or both sides of the filter device and is located at the upper end and / or the lower end of the filter device, see Figure 2 , Figure 3 As shown, the shaft portion 2 of this embodiment is located on one side of the filter device, and an shaft portion 2 is respectively provided at the upper end and the lower end of the side; the guide rail 5 extends from one end of the side wall where it is located to the other end of the side wall, so that the shaft portion 2 slides from one end of the air outlet side wall to the other end thereof, thereby enabling the filter device to complete a 180° flipping action.

[0041] The shaft 2 movably connected to one end of the guide rail 5 slides to the other end of the guide rail 5, and because the shaft 2 can rotate 180° in the guide rail 5, the filter device can be turned over 180°. In this way, the inner side of the original filter device can be turned to the outer side, and the outer side of the original filter device can be turned to the inner side, so that both sides of the filter device can be fully utilized for filtering, thereby improving the utilization rate and service life of the filter device.

[0042] In the process of sliding and rotating the filter device, the filter device can also be stopped at any suitable angle and position, see Figure 2As shown, clean and replace the filter device.

[0043] In order to facilitate the cleaning and replacement of the filter device, the filter device can be stably maintained at an appropriate position and angle. Figure 1-Figure 4 As shown, the connection structure of this embodiment also includes a supporting telescopic component 3, one end of which is rotatably connected to the side wall of the air outlet, and the other end of which is rotatably connected to the filter device. When the filter device rotates, it can push or pull the supporting telescopic component 3 to extend and retract.

[0044] The above-mentioned supporting telescopic component 3 is connected to the filter device and the side wall of the air outlet, and is rotatably connected to the filter device and the side wall of the air outlet respectively. At the same time, the telescopic setting during the rotation of the filter device makes the filter device always connected to the supporting telescopic component 3 during the entire rotation process, thereby ensuring the stability of the filter device during the rotation and sliding process, making the movement of the filter device smoother, and at the same time making it possible for the filter device to stay relatively stably at any position of the guide rail 5, so as to facilitate the staff to clean and replace the filter device.

[0045] As an optional embodiment, the end of the supporting telescopic assembly 3 is rotatably connected to the middle section of the upper side and / or the lower side of the filtering device, see Figure 2 , Figure 3 As shown, in this embodiment, the ends of the supporting telescopic components 3 are rotatably connected to the middle sections of the upper and lower sides of the filtering device. When there are two groups of ends of the supporting telescopic components 3 that are respectively rotatably connected to the upper and lower sides of the filtering device, the connection parts of the two groups of supporting telescopic components 3 and the filtering device exist on the same straight line.

[0046] See also Figure 2 and Figure 3 As shown, in this embodiment, a group of supporting telescopic components 3 are connected to the upper and lower sides of the filter device, and the connection parts of the two groups of supporting telescopic components 3 and the filter device exist on the same straight line, which is arranged parallel to the straight line where the two shaft portions 2 are located, so as to improve the stability of the filter device during rotation and sliding, and when the filter device stays at a certain angle, the supporting telescopic components 3 play a supporting and fixing role.

[0047] The above-mentioned “middle section” refers to a region located in the middle of the upper and lower sides of the filter device, rather than a specific position point.

[0048] This embodiment provides a specific implementation of a supporting telescopic assembly 3. Figure 2 and Figure 4 As shown, the supporting telescopic assembly 3 includes an inner rod 31 and a sleeve rod 32, wherein: a cavity is provided in the sleeve rod 32, at least part of the inner rod 31 extends into and is confined in the cavity, and when the filter device rotates, it can push or pull at least part of the inner rod 31 to slide along the cavity.

[0049] See also Figure 4 As shown, a limiting step 311 is provided on the inner rod 31, and the limiting step 311 divides the inner rod 31 into a portion that can extend into the cavity of the sleeve rod 32 and a portion that is always located outside the cavity; similarly, a step portion (not shown in the figure) is provided in the cavity of the sleeve rod 32 to prevent the inner rod 31 from completely slipping out. The above-mentioned structure cooperates to prevent the inner rod 31 from completely extending into the sleeve rod 32, and prevents the inner rod 31 from completely slipping out of the sleeve rod 32.

[0050] As the filter device rotates, its distance from the side wall of the air outlet changes continuously; the structure in which the inner rod 31 and the sleeve rod 32 cooperate with each other can pull or push the inner rod 31 to slide along the cavity of the sleeve rod 32 when the filter device rotates, thereby supporting the extension and contraction of the telescopic assembly 3 and ensuring that the filter device can rotate smoothly.

[0051] As an alternative embodiment, see Figure 4 As shown, the supporting telescopic component 3 of this embodiment includes mounting holes 33, and the mounting holes 33 are arranged at both ends of the supporting telescopic component 3, and one of the two mounting holes 33 is rotatably connected to the side wall of the air outlet, and the other is rotatably connected to the outer wall of the filtering device.

[0052] One of the mounting holes 33 can be connected to the shaft body on the side of the filter device, such as Figure 2 As shown, the filter device is rotatably connected to the supporting telescopic assembly 3, and the mounting hole at the other end is rotatably connected to the side wall of the air outlet in the same way.

[0053] In order to prevent the filter device from being opened by mistake when it is not necessary to rotate the filter device, the filter device can close the air outlet. Figure 2 As shown, the connection structure also includes a locking member 8, which passes through the supporting telescopic assembly 3 to lock it with the side wall of the air outlet. By rotating the locking member 8, the supporting telescopic assembly 3 can rotate around the shaft 2 as the axis.

[0054] The locking member 8 can be a bolt, and the bolt passes through the mounting hole 33 on the supporting telescopic assembly 3 and is threadedly connected to the side wall of the air outlet. When the locking member 8 is tightened, the filter device will not start under the pull or push of an external force, and the air outlet is always kept closed to prevent the filter device from opening by mistake. When the filter device needs to be rotated, the locking member 8 is loosened, and the end of the supporting telescopic assembly 3 can be rotated between the side wall of the air outlet and the end of the locking member 8. At this time, the external force can push the filter device to rotate or slide.

[0055] See also Figure 1As shown, in this state, the shaft 2 and the locking member 8 are respectively located at the two ends of the guide rail 5. Since the shaft 2 of this embodiment can slide to the other end of the guide rail 5 and realize the flipping of the filter device, when the shaft 2 slides to the position on the same side of the guide rail 5 as the locking member 8, in order to prevent the shaft 2 from affecting the retraction of the supporting telescopic assembly 3 and further fix the filter device at the same time, the filter device is further fixed. Figure 4 , Figure 5 and Figure 6 As shown, the end of the supporting telescopic component 3 facing away from the filtering device is located at the end of the guide rail 5, and a card slot 34 is provided on the end of the supporting telescopic component 3. When the shaft 2 slides from one end of the guide rail 5 to the other end thereof, the card slot 34 can be engaged with the shaft 2.

[0056] Combination Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, when the shaft 2 slides to the other side of the guide rail 5 and the filter device is turned over, the shaft 2 is engaged in the slot 34 to fix the shaft 2 and the telescopic support assembly 3 to prevent the shaft 2 from continuing to slide, and at the same time, the locking piece 8 is tightened to prevent the telescopic support assembly 3 from continuing to rotate, thereby locking the shaft 2 of the filter device, the telescopic support assembly 3 and the side wall of the air outlet.

[0057] The filter device connection structure of this embodiment can be operated in the following manner when the filter device needs to be cleaned or replaced:

[0058] See also Figure 1 As shown, loosen the locking member 8 and pull the side of the filter device opposite to the shaft portion 2. At this time, the filter device can rotate around the shaft portion 2 as the axis, and the shaft portion 2 slides along the guide rail 5; see Figure 2 As shown, the filter can be cleaned or replaced in this position and angle; or, see Figure 3 , continue to rotate the filter device, when the shaft 2 slides to the end of the guide rail 5 close to the locking piece 8, and the filter device is turned over 180 degrees, the shaft 2 is clamped in the clamping groove 34, and the locking piece 8 is tightened to lock the shaft 2 of the filter device, the supporting telescopic assembly 3 and the side wall of the air outlet. Of course, after loosening the locking piece 8 to disengage the shaft 2 from the clamping groove 34, the filter device can also be reversely rotated 180 degrees and restored to the original position. Figure 1 The above operation process is simple and easy. During the rotation process, the filter and the dust on the condenser fins can be cleaned daily without disassembling any parts. At the same time, if the filter needs to be replaced, the filter can be directly replaced without disassembling the panel or frame 1, eliminating the tedious disassembly and assembly work.

[0059] Embodiment 2

[0060] This embodiment provides an air outlet assembly, including an air outlet and a filter device, wherein the air outlet and the filter device are connected via the filter device connection structure. The air outlet can be a return air outlet or an air outlet.

[0061] The air outlet assembly of this embodiment, because it has the above-mentioned filter device connection structure, is also convenient for disassembly and replacement of the filter device at the air outlet.

[0062] As an alternative embodiment, see Figure 2 and Figure 3 As shown, the filter device includes a frame 1 and a filter screen, the shaft 2 is located on one side or both sides of the filter device and at the upper end and / or lower end of the filter device, and the filter screen is detachably fixed to the frame 1.

[0063] See also Figure 2 and Figure 3 As shown, the elbow of this embodiment is located on one side of the filter device and at the upper and lower ends of the filter device. The filter screen can be detachably connected to the frame 1 by screw fixing, or detachably connected to the frame 1 by snap fixing, so as to facilitate replacement.

[0064] As an alternative embodiment, see Figure 2 and Figure 3 As shown, the filter screen includes one layer or more than two layers, and the mesh numbers of the filter screens in different layers are the same or different.

[0065] Preferably, the filter screen includes two layers (or more than two layers), and the mesh numbers of the filter screens in different layers are different. Specifically, the mesh number of the outer filter screen 6 is 48 meshes (the number of holes in the area per square centimeter is not limited to this mesh number), and the mesh number of the inner filter screen 7 is 24 meshes, which is 1 / 2 of the mesh number of the outer filter screen 6, so as to achieve double-layer filter screen protection against objects and dust without affecting the air volume. The outer filter screen 6 can protect larger debris and mosquitoes, and improve the purification effect of the incoming air.

[0066] Among them, different types of filters can be selected for installation on air conditioners with different performance requirements, which can be coarse-efficiency, medium-efficiency, high-efficiency filters and so on.
