[0041] The realization of the purpose, functional features and advantages of the present invention will be further described in conjunction with the embodiments with reference to the accompanying drawings. Specific embodiments

[0042] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0043] It should be noted that the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of the technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0044] The present invention provides a humidifying structure.

[0045] In the embodiment of the present invention, as Figures 1 to 6 shown, the humidifying structure includes: a water tank 10 for containing liquid; a floating frame 20 movably disposed in the water tank 10 to float with the liquid level in the water tank 10; and a wet film 30 mounted on the floating frame 20 to float with the floating frame 20, and the bottom of the wet film 30 can contact the liquid in the water tank 10 to absorb the liquid.

[0046] In this embodiment, the water tank 10 is arranged in a trough-shaped structure with an open top. The liquid contained in the water tank 10 can be water or aromatherapy liquid. If the water tank 10 contains water, the humidifying structure mainly functions to humidify the air; if the water tank 10 contains aromatherapy liquid, the humidifying structure mainly functions to add fragrance to the air. The floating frame 20 and the water tank 10 may not form a connection relationship, and it is only necessary that the floating frame 20 can float in the water tank 10 as the liquid level rises and falls. The wet film 30 can be an organic wet film 30, an inorganic wet film 30, a metal wet film 30, etc. The wet film 30 has a certain water absorption capacity. When the wet film 30 comes into contact with water, the wet film 30 can be filled with water under its own adsorption capacity, so that the entire wet film 30 is wetted by water. When air passes through the water-absorbed wet film 30, the water adsorbed on the wet film 30 will move with the air and separate from the wet film 30, which increases the humidity of the air flowing through the wet film 30 and realizes the humidification of the air. Since the wet film 30 remains in contact with the liquid in the water tank 10, the wet film 30 can synchronously absorb water to replenish water when the water content is lost, so that the wet film 30 remains in a water-saturated state. When the liquid in the water tank 10 is exhausted, the wet film 30 will drop to the bottom of the water tank 10 with the floating frame 20. The user can judge whether the water tank 10 is short of water through the height change of the wet film 30 in the water tank 10 and replenish water to the water tank 10 in time.

[0047] The humidifying structure of the present invention enables the wet film 30 to float in the water tank 10 by adopting the floating frame 20. The bottom of the wet film 30 can contact the liquid in the water tank 10 to absorb the liquid, thereby humidifying the air flowing through the wet film 30. Thus, the humidification of the air is achieved with a simpler structure, and the cost of the humidifying structure is reduced; in addition, the wet film 30 will continuously replenish water during the humidification process. If the liquid in the water tank 10 is exhausted, the wet film 30 will drop to the bottom of the water tank 10. The user can judge whether the water tank 10 needs to be replenished through this state, so as to prompt the water shortage state of the water tank 10 in a simpler and more convenient way, further simplifying the humidifying structure and reducing the cost.

[0048] Specifically, as Figure 2 and Figure 4As shown, in the floating state, the top of the wet film 30 protrudes above the water tank 10; in the non-floating state, the top of the wet film 30 is lower than or flush with the water tank 10. In this embodiment, the humidifying structure can be disposed at the air outlet 51 of the air conditioner indoor unit during application. When the wet film 30 is saturated with water absorption and there is still water in the water tank 10, the wet film 30 is in a floating state together with the floating frame 20. At this time, regardless of the liquid level height, the top of the wet film 30 always protrudes above the water tank 10, so that the air flow can directly flow through the wet film 30 to fully humidify and improve the humidifying effect. When the water in the water tank 10 is exhausted, the bottom of the wet film 30 drops to the bottom of the water tank 10, that is, in the non-floating state. At this time, the top of the wet film 30 does not protrude above the water tank 10, so that the user can more intuitively judge whether the water tank 10 is short of water and replenish water in time.

[0049] In practical applications, as Figure 5 shown, the floating frame 20 is provided with a mounting hole 21, and the bottom of the wet film 30 is inserted into the mounting hole 21. In this embodiment, the mounting hole 21 penetrates through the top and bottom of the additional part, and the bottom of the wet film 30 is inserted into the mounting hole 21 to increase the matching area between the wet film 30 and the floating frame 20, thereby improving the matching strength between the wet film 30 and the floating frame 20; at the same time, the bottom of the wet film 30 can also be stably in contact with the liquid in the water tank 10 through the mounting hole 21 to improve the stability of the water absorption process.

[0050] In one embodiment, as Figures 1 to 5 shown, the humidifying structure further includes a bracket 40. The wet film 30 is detachably matched with the bracket 40, and the bracket 40 is detachably connected to the floating frame 20. In this embodiment, the wet film 30 is installed on the floating frame 20 through the bracket 40, so that the connection between the wet film 30 and the floating frame 20 is more stable. The wet film 30 is detachably matched with the bracket 40, and the bracket 40 is detachably connected to the floating frame 20, which is convenient for inspecting or replacing the wet film 30.

[0051] Specifically, as shown in Figure 1 and Figure 5 shown, the bracket 40 includes a first frame 41 and a second frame 42 that are spliced together. After the first frame 41 and the second frame 42 are spliced, an installation space is formed, and the wet film 30 is fixed in the installation space. In this embodiment, the wet film 30 is arranged in a block shape. The frame bars of the first frame 41 and the second frame 42 can be in direct contact or indirectly connected, as long as the first frame 41 and the second frame 42 are connected to form an installation space. It should be noted that the top of the installation space can be closed or open, which is not limited here, as long as the wet film 30 is fixed in the installation space. After the wet film 30 is fixed in the installation space, the bracket 40 and the wet film 30 as a whole are inserted into the mounting hole 21, thereby realizing the cooperation between the wet film 30 and the floating frame 20.

[0052] It should be noted that if there are descriptions such as "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and should not be construed as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature.

[0053] In practical applications, as Figure 5 shown, one of the frame bars of the first frame 41 and the second frame 42 is provided with a buckle 411, and the other frame bar is provided with a slot 421 adapted to the buckle 411. In this embodiment, two of the frame bars of the first frame 41 are provided with slots 421, and the other two frame bars are provided with protruding buckles 411; the positions and quantities of the slots 421 and the buckles 411 on the frame bars of the second frame 42 correspond to those of the first frame 41. Through the snap-fit of the buckle 411 and the slot 421, the splicing of the first frame 41 and the second frame 42 is more stable and convenient for disassembly.

[0054] In one embodiment, as Figure 5 shown, a positioning groove 211 is concavely provided on the edge of the hole of the mounting hole 21, and a positioning protrusion 43 adapted to the positioning groove 211 is convexly provided on the side wall of the bracket 40. In this embodiment, the mounting hole 21 is provided as a direction hole, the number of the positioning grooves 211 is two, the two positioning grooves 211 are concavely provided at the diagonal corners of the edge of the mounting hole 21, and the number and position of the positioning protrusions 43 correspond to those of the mounting hole 21. When the bracket 40 is inserted into the mounting hole 21, the positioning protrusion 43 is embedded in the positioning groove 211 to limit the insertion depth of the bracket 40, so that the wet film 30 can be more exposed above the floating frame 20, increasing the contact area between the wet film 30 and the air and improving the humidifying effect.

[0055] Specifically, as Figure 5 shown, a limiting groove 22 is provided on the side wall of the floating frame 20, and a limiting rib 11 corresponding to the limiting groove 22 is convexly provided on the inner wall of the water tank 10; and / or, a limiting rib 11 is convexly provided on the side wall of the floating frame 20, and a limiting groove 22 corresponding to the limiting rib 11 is provided on the inner wall of the water tank 10. In this embodiment, the limiting groove 22 extends along the height direction of the floating frame 20 and penetrates the top and bottom of the floating frame 20, the limiting rib 11 extends along the height direction of the water tank 10, the number of the limiting ribs 11 is two and they are provided on two opposite inner walls of the water tank 10, and the number and position of the limiting grooves 22 correspond to those of the limiting ribs 11. When the floating frame 20 is arranged in the water tank 10, the limiting rib 11 and the limiting groove 22 are in sliding fit, and the limiting rib 11 and the limiting groove 22 may not be in contact, so as to reduce the resistance of the floating frame 20 to rise and fall, and only need to meet the requirement that their cooperation can prevent the floating frame 20 from shifting laterally, making the floating process of the floating frame 20 more stable.

[0056] It should be noted that the meaning of "and / or" appearing throughout the text is that it includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, or solution B, or the solution where both A and B are satisfied simultaneously.

[0057] In practical applications, such as Figure 5 As shown, a limiting protrusion 12 is convexly provided at the upper end of the inner wall of the water tank 10, and a limiting clamping protrusion 23 corresponding to the limiting protrusion 12 is convexly provided on the side wall of the floating frame 20. When the floating frame 20 floats to a preset position, the bottom of the limiting protrusion 12 abuts against the top of the limiting clamping protrusion 23. In this embodiment, when the limiting protrusion 12 abuts against the limiting clamping protrusion 23, the position where the floating frame 20 is located is the highest position that it can reach in the water tank 10. By making the limiting protrusion 12 and the limiting clamping protrusion 23 cooperate to limit the floating height of the floating frame 20 in the water tank 10, it is possible to prevent the wet film 30 from falling out of the water tank 10 due to the excessive position of the floating frame 20, and the stability of the humidifying structure is improved.

[0058] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present invention, then such directional indications are only used to explain the relative positional relationship and movement conditions between components in a certain specific posture (as shown in the drawings). If this specific posture changes, then the directional indications will also change accordingly.

[0059] Such as Figures 7 to 12 As shown, the present invention also proposes an air conditioner indoor unit, which includes a housing 50 and a humidifying structure. The specific structure of the humidifying structure refers to the above embodiments. Since this air conditioner indoor unit adopts all the technical solutions of the above-mentioned all embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, and will not be elaborated one by one here. Among them, the housing 50 is provided with an air outlet 51, and the humidifying structure is arranged at the air outlet 51 to humidify the air flowing through the humidifying structure. The air conditioner indoor unit can be selected as a floor-standing air conditioner indoor unit or a vertical wall-mounted air conditioner indoor unit, etc.; the present invention takes the floor-standing air conditioner indoor unit as an example for description, but the present invention is not limited thereto.

[0060] In one embodiment, such as Figure 7 and Figure 9As shown, the air conditioner indoor unit further includes a wind guiding frame 60 installed at the air outlet 51, and the humidifying structure is installed on the wind guiding frame 60. In this embodiment, the air outlet 51 generally extends in the up-down direction (i.e., the vertical direction). Among them, the wind guiding frame 60 is used for guiding air to adjust the air supply direction and air supply uniformity of the air conditioner indoor unit. The air conditioner indoor unit generally further includes an indoor heat exchanger disposed in the heat exchange air duct, and the indoor heat exchanger is used for adjusting the indoor air temperature, such as refrigeration or heating. The air conditioner indoor unit further includes a wind wheel disposed in the heat exchange air duct, and the wind wheel is used for driving air flow; among them, the wind wheel is a rotatable cross-flow wind wheel and is disposed on the air outlet side of the indoor heat exchanger. When the air conditioner indoor unit works, the wind wheel drives the indoor air to flow, and drives the indoor air to enter the heat exchange air duct from the air inlet. The flowing air exchanges heat with the indoor heat exchanger and then flows to the air outlet 51, and is sent out from the air outlet 51 through the wind guiding frame 60. The humidifying structure is installed on the wind guiding frame 60, which can make the installation of the humidifying structure in the housing 50 more compact and reduce the occupied space.

[0061] Specifically, as Figure 11 and Figure 12 shown, the humidifying structure is installed at the rear side of the wind guiding frame 60, and the wind guiding frame 60 is rotatably connected to the housing 50 so that the humidifying structure can be rotated to the front side of the wind guiding frame 60. In this embodiment, the wind guiding frame 60 has a rotation axis extending in the up-down direction, and the wind guiding frame 60 can rotate around the rotation axis, so that the humidifying structure can be rotated to the front side of the wind guiding frame 60 to facilitate the user to replenish water to the water tank 10.

[0062] In one embodiment, as Figures 7 to 10 shown, the wind guiding frame 60 includes a bottom frame 61 and a frame body 62. The frame body 62 is disposed at the front side of the top of the bottom frame 61, and the humidifying structure is installed on the top of the bottom frame 61; the bottom frame edge of the frame body 62 is lower than or flush with the top of the water tank 10 of the humidifying structure.

[0063] In this embodiment, the air conditioner indoor unit further includes a driving motor for driving the wind guiding frame 60 to rotate. The driving shaft of the driving motor cooperates with the bottom frame 61. The bottom frame 61 is used to support the rotation of the frame body 62. At the same time, the top of the bottom frame 61 also provides an installation position for the humidifying structure. The humidifying structure is installed on the top of the bottom frame 61, which can not only prevent obstruction to the air outlet, but also effectively humidify the air flowing through the air outlet 51. The bottom frame edge of the frame body 62 does not protrude above the top of the water tank 10, so that the wet film 30 in the floating state can remain protruding above the bottom frame edge. Thus, the air flowing through the wet film 30 is not blocked by the bottom frame edge, so that the humidified air can be smoothly blown out, further improving the humidifying effect.

[0064] Specifically, as Figures 7 to 10As shown, a mounting platform 611 protrudes from the top of the chassis 61, and a mounting groove 13 adapted to the mounting platform 611 is formed at the bottom of the water tank 10 of the humidifying structure. In this embodiment, the mounting groove 13 extends in the front-rear direction. The cooperation between the mounting groove 13 and the mounting platform 611 can make the installation of the water tank 10 on the chassis 61 more stable and improve the stability of the humidifying structure.

[0065] In one embodiment, as Figures 7 to 10 shown, one end of the mounting groove 13 penetrates through the side wall of the water tank 10 to form a sliding interface 14, and a limiting strip 131 is connected to the edge of the opening of the mounting groove 13; a limiting space 612 is recessed in the lower end of the side wall of the mounting platform 611. The mounting platform 611 can slide relative to the mounting groove 13 through the sliding interface 14 to a fixed fit, so that the limiting strip 131 enters the limiting space 612. In this embodiment, the front end of the mounting groove 13 penetrates through the front side wall of the water tank 10, and the limiting strip 131 extends in the front-rear direction. Limiting spaces 612 are recessed in the lower ends of the left and right side walls of the mounting platform 611, and the limiting spaces 612 extend in the front-rear direction. The mounting platform 611 can enter the mounting groove 13 from the sliding interface 14, so that the limiting strip 131 synchronously enters the limiting space 612. The cooperation between the mounting groove 13 and the mounting platform 611 can limit the water tank 10 in the transverse direction, and the cooperation between the limiting strip 131 and the limiting space 612 can limit the water tank 10 in the longitudinal direction, thereby making the installation of the water tank 10 more stable.

[0066] Specifically, as Figure 6 and Figure 8 shown, a limiting groove 613 is formed at the top of the mounting platform 611, and a limiting block 132 adapted to the limiting groove 613 protrudes from the bottom of the mounting groove 13. In this embodiment, while the mounting platform 611 enters the mounting groove 13 along the sliding interface 14, the limiting block 132 enters the limiting groove 613. The cooperation between the mounting platform 611 and the mounting groove 13 can limit the water tank 10 in the front-rear direction, and the cooperation between the limiting block 132 and the limiting groove 613 can limit the water tank 10 in the left-right direction, thereby making the installation of the water tank 10 more stable.

[0067] In practical applications, as Figure 8 shown, a guiding inclined surface 614 connected to the opening of the limiting groove 613 is formed at the top of the mounting platform 611 to guide the limiting block 132 towards the limiting groove 613. In this embodiment, the guiding inclined surface 614 is formed at the rear side part of the top of the mounting platform 611. The guiding inclined surface 614 can not only make the limiting block 132 enter the limiting groove 613 more smoothly, but also make the mounting platform 611 enter the mounting groove 13 more smoothly, thereby reducing the installation difficulty of the humidifying structure. A guiding groove corresponding to the limiting block 132 can also be formed on the guiding inclined surface 614, so that the limiting block 132 can enter the limiting groove 613 more smoothly along the guiding groove.

[0068] The present invention also provides an air conditioner, which includes an indoor unit of the air conditioner. The specific structure of the indoor unit of the air conditioner refers to the above-mentioned embodiment. Since the air conditioner adopts all the technical solutions of the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be elaborated one by one here.

[0069] The above are only the optional embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or any direct / indirect application in other related technical fields is included in the patent protection scope of the present invention.
