DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in combination with the specific embodiments of the utility model and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The technical solutions provided by various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0026] Reference Figures 1 to 7 As shown, the embodiment of the utility model provides an air intake structure of a central air conditioner that is easy to clean, including an air intake grille 1 and a bottom plate 2, wherein the bottom plate 2 is provided with a vent 21, and the size of the air intake grille 1 is adapted to the size of the vent 21; the lower end of the bottom plate 2 is connected to a rectangularly distributed enclosure 22, and a group of vertical partitions 23 are mirror-imaged on the left and right sides of the vent 21 of the bottom plate 2, and the two vertical partitions 23 form independent chambers 24 with the left and right sides of the enclosure 22 respectively; the left and right sides of the air intake grille 1 are provided with a connecting portion 11, and the inner side end of the connecting portion 11 is provided with a transversely telescopic baffle 3, and the bottom end of the vertical partition 23 is provided with a flange 231 that extends transversely into the corresponding chamber 24;

[0027] The two connecting parts 11 are respectively inserted into the two chambers 24, and extend to the top of the corresponding flanges 231 through the two baffles 3, so as to realize the detachable assembly of the air inlet grille 1 and the two vertical partitions 23, and the air inlet grille 1 faces the vent 21; a dust filter layer 4 is also arranged between the air inlet grille 1 and the bottom plate 2, and the dust filter layer 4 can be made of a filter screen or filter cotton, and the dust filter layer 4 needs to be cleaned or replaced regularly to ensure the ventilation effect of the air inlet structure of the air conditioner;

[0028] In this embodiment, the connecting parts 11 at both ends of the air inlet grille 1 are respectively extended into the two chambers 24, and then the baffle 3 is extended to the top of the flange 231, and the baffle 3 is shielded by the flange 231, so that the detachable assembly between the air inlet grille 1 and the vertical partition 23 can be achieved, and the base plate 2 is installed on the wall, and the base plate 2 is aligned with the air outlet of the air conditioner reserved on the wall; when the air conditioner needs to be cleaned, that is, to clean the dust filter layer 4, it is only necessary to retract the two baffles 3 to be separated from the top of the corresponding flange 231, and the air inlet grille 1 and the two connecting parts 11 can be removed from the base plate 2 together, so that the dust filter layer 4 can be cleaned or replaced. Compared with the method of disassembling the air inlet grille 1 by bolts in the prior art, it is more convenient and quick to clean the filter layer, and does not require the aid of additional auxiliary tools, and is more suitable for self-cleaning by family members.

[0029] Specifically, each connecting part 11 is hollow inside and open at the lower end. A through groove 111 is also provided at the top inner end of the connecting part 11. The baffle 3 is slidably arranged in the through groove 111. A vertical plate 12 is provided inside the connecting part 11 and is fixedly connected to the baffle 3. At least one first guide rod 112 is provided inside the connecting part 11. A first spring 13 is installed on the first guide rod 112. The first guide rod 112 passes through the vertical plate 12 and is slidably connected thereto. The spring abuts against the vertical plate 12 so that the baffle 3 passes through the through groove 111 and extends to the outside of the connecting part 11.

[0030] In the present embodiment, two first guide rods 112 are provided, so as to increase the sliding stability of the vertical plate 12. Under the action of the spring, the baffle 3 can always be in an extended state without being subjected to external force. When installing the air inlet grille 1, it is necessary to move the vertical plate 12 so that the baffle 3 is completely retracted into the through groove 111. In this case, the connecting portion 11 can smoothly pass through the flange 231 and enter the corresponding chamber 24. Then, the vertical plate 12 is loosened, and under the action of the spring, the baffle 3 can be extended again and be above the flange 231. Under the action of gravity, the air inlet grille 1 and the connecting portion 11 descend together, and the baffle 3 contacts the flange 231 to realize the assembly of the air inlet grille 1 on the enclosure 22 on the bottom plate 2. This assembly method is faster and household members can complete the disassembly of the air inlet grille 1 by hand without the aid of other auxiliary tools, which is convenient for cleaning the filter layer.

[0031] Specifically, the lower end of the vertical plate 12 is set as a first inclined surface 121, and a wedge block 14 is longitudinally slidably provided inside the connecting portion 11, and the upper end of the wedge block 14 is provided with a second inclined surface 141 that cooperates with the first inclined surface 121; the wedge block 14 is pressed upward, and the vertical plate 12 can be driven to move horizontally through the cooperation of the first inclined surface 121 and the second inclined surface 141, so that the baffle 3 is retracted into the connecting portion 11;

[0032] A connecting plate 15 is installed at the opening of the connecting portion 11, and a button 142 is installed at the lower end of the wedge block 14. The button 142 passes through the connecting plate 15 to the outside of the connecting portion 11 and is slidably connected to the connecting plate 15. The cross-sectional dimension of the button 142 is smaller than the cross-sectional dimension of the wedge block 14. The connecting plate 15 limits the travel of the wedge block 14.

[0033] In this embodiment, under the action of the first spring 13, the vertical plate 12 abuts against the vertical partition 23, and the wedge block 14 abuts against the connecting plate 15. The user only needs to push the button 142 upward to completely retract the baffle 3 to achieve the installation or removal of the air inlet grille 1, and the operation process is more convenient.

[0034] In another embodiment, if Figures 3 to 5 As shown, a bracket 25 is installed in each chamber 24, and the bracket 25 is provided with at least one set of second guide rods 26 that longitudinally pass through the bracket 25 and are slidably connected thereto, and a limiting plate 27 is provided at the upper end of the second guide rod 26 and is used to limit the second guide rod 26, and a pressing plate 28 is provided at the lower end of the second guide rod 26, and a second spring 29 is also provided on the second guide rod 26, and the second spring 29 is located between the bracket 25 and the pressing plate 28;

[0035] Taking into account that the installation of the air intake structure is not concentrated on the upper end of the wall, it will also be installed on the side of the wall according to the situation. In this case, the baffle 3 will not be affected by gravity and will not abut on the flange 231, and the air intake grille 1 will be unstable and easy to shake. For this reason, a pressure plate 28 with elastic action is provided. When the air intake grille 1 and the vertical partition 23 are assembled, the pressure plate 28 is elastically abutted on the connecting portion 11 through the second spring 29. In this way, when the air intake structure is installed at any position on the wall, it can be ensured that the baffle 3 abuts on the flange 231, thereby ensuring the stability of the air intake grille 1.

[0036] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
