[0034] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0035] Reference below Figure 1-Figure 9 The filter screen 2 according to the first embodiment of the utility model is described.

[0036] like Figure 2-Figure 9 As shown, the filter net 2 according to the embodiment of the first aspect of the utility model is used in an air conditioner indoor unit 100, and the air conditioner indoor unit 100 has an air inlet 141 and an air outlet 142. The filter net 2 includes: a filter part 21 and a support part 22. The filter part 21 is suitable for being arranged at the position of the air inlet 141; the support part 22 is connected to one end of the filter part 21 facing the air outlet 142, and the support part 22 is plate-shaped, and a through hole 221 is formed on the support part 22, and the through hole 221 connects the two side spaces of the support part 22 in the thickness direction.

[0037] For example, the air conditioner indoor unit 100 has an air inlet 141 and an air outlet 142, and the filter unit 21 is located on the upper side of the filter net 2 and is arranged at the position of the air inlet 141 of the air conditioner indoor unit 100. Specifically, the filter unit 21 includes a frame 211 and a filter element, the frame 211 is grid-shaped and forms a through hole 2110, and the filter element is connected to the frame 211 and covers the through hole 2110 on the frame 211. The frame 211 includes a plurality of first ribs 2111 and a plurality of second ribs 2112, the plurality of first ribs 2111 extend left and right and are arranged at intervals in the up and down directions, the plurality of second ribs 2112 extend up and down and are arranged at intervals in the left and right directions, and each first rib 2111 is connected to a plurality of second ribs 2112 to form a grid-shaped frame 211. Further, the filter net 2 can be multiple, and the plurality of filter nets 2 are arranged at intervals left and right.

[0038] The support part 22 is located at the lower side of the filter part 21, and its upper edge is connected to the lower edge of the filter part 21. The support part 22 is arranged at one end of the filter part 21 facing the air outlet 142 of the air conditioner indoor unit 100, and the support part 22 is plate-shaped, and a through hole 221 is arranged thereon. The space in front of the through hole 221 and the space in the rear of the through hole 221 are connected to each other through the through hole 221, providing a passage for air circulation in the space.

[0039] It should be noted that the air contains a certain amount of water vapor. When the temperature in the environment drops to a certain level, part of the water vapor in the air begins to liquefy into dewdrops. This specific temperature is called the dew point temperature of the air. When the air encounters a medium with a lower temperature, the temperature of the air around the medium will drop rapidly. When the temperature of the air around the medium drops below the dew point temperature, part of the water vapor in the air will liquefy into condensation, which will adhere to the medium and gradually form water droplets.

[0040] When the air conditioner 100 is operated in a high temperature and high humidity environment, air rich in water vapor enters the air conditioner 100 from the air inlet 141 of the air conditioner 100 under the driving action of the wind wheel, rotates along the wind wheel, and is discharged through the air outlet 142 of the air conditioner 100. During the air circulation process, part of the air rich in water vapor escapes to the support portion 22 of the filter 2 after rotating along the wind wheel.

[0041] It should be noted that when the air conditioner of the prior art is in operation, the air located in front of the support part of the filter mesh circulates slowly due to the small structural gap of the air conditioner indoor unit at this location. Under the refrigeration effect of the air conditioner indoor unit, the temperature of the support part of the filter mesh gradually decreases, and the air escaping to the front of the support part of the filter mesh forms a certain temperature difference with the support part of the filter mesh. Under the effect of the temperature difference, the water vapor in the air here is partially liquefied into condensation and attached to the support part of the filter mesh. The condensation at the support part of the filter mesh flows downward under the action of gravity and eventually drips from the air outlet of the air conditioner indoor unit. At the same time, the support part of the filter mesh will reduce the air volume and air outlet effect at the air outlet of the air conditioner indoor unit, affecting work efficiency and user experience.

[0042] In this embodiment, a through hole 221 is provided on the support portion 22 of the filter 2, and the space in front of the through hole 221 and the space in the rear of the through hole 221 are interconnected through the through hole 221, providing a passage for air circulation in the space. When the air conditioner indoor unit 100 is operated in a high temperature and high humidity environment, the air escaping to the front of the support portion 22 of the filter 2 can flow into the space in the rear of the support portion 22 of the filter 2 through the through hole 221 on the support portion 22, and finally flow to the air outlet 142 through the structural gap of the air conditioner indoor unit 100 for discharge. The air in the spaces on both sides of the support portion 22 continuously circulates through the through hole 221 to prevent the water vapor in the air from liquefying into condensation.

[0043] According to the filter 2 of the embodiment of the utility model, by providing a through hole 221 on the support part 22 of the filter 2 to connect the two side spaces in the thickness direction of the support part 22, the generation of condensation on the filter 2 can be effectively reduced when the air conditioner indoor unit 100 is running in a high temperature and high humidity environment, and thus the condensation dripping along the filter 2 under the action of gravity can be effectively reduced. At the same time, the through hole 221 of the support part 22 of the filter 2 can speed up the circulation of air, thereby increasing the air volume of the air outlet 142, enhancing the air outlet effect, improving work efficiency, and ultimately effectively improving the user experience.

[0044] In one embodiment of the present invention, Figure 5 As shown, the through hole 221 is formed on a side of the support portion 22 away from the filter portion 21 .

[0045] Specifically, the through hole 221 is arranged at the lower side of the support portion 22 of the filter 2 and as far away from the filter portion 21 of the filter 2 as possible. When the air conditioner indoor unit 100 is operated in a high temperature and high humidity environment, the escaped air enters the space between the filter portion 21 and the panel 13. The through hole 221 is arranged on the side of the support portion 22 away from the filter portion 21, and the air in the lowest space between the filter portion 21 and the panel 13 can quickly flow into the lowest space between the filter portion 21 and the fixing frame 15 through the through hole 221, and finally be discharged through the air outlet 142. The air in the upper space between the filter portion 21 and the panel 13 flows downward under the action of air pressure, flows into the lowest space between the filter portion 21 and the fixing frame 15 after passing through the through hole 221, and finally be discharged through the air outlet 142.

[0046] Therefore, by setting the through hole 221 as far away from the filter 21 as possible, the fluidity of air flowing from the space in front of the through hole 221 to the space behind the through hole 221 can be effectively improved, and the water vapor in the air can be further prevented from liquefying into condensation, thereby reducing the generation and dripping of condensation on the support portion 22 of the filter 2. At the same time, by setting the through hole 221 as far away from the filter 21, the air volume of the air outlet 142 can be further increased.

[0047] In one embodiment of the present invention, Figure 5 As shown, there are multiple through holes 221 , and the multiple through holes 221 are arranged at intervals.

[0048] For example, a plurality of hole groups are provided on the support portion 22 of the filter 2, and the plurality of hole groups are arranged at intervals in the up-down direction, and each hole group includes a plurality of through holes 221 arranged at intervals in the left-right direction. Further, the through holes 221 can be distributed along the left-right direction of the support portion 22 of the filter 2, on the side of the support portion 22 away from the filter 21. When the air conditioner indoor unit 100 is operated in a high temperature and high humidity environment, the escaping air enters the front space of the support portion 22 of the filter 2 under the drive of the wind wheel, and flows into the rear space of the support portion 22 through the plurality of through holes 221 of the support portion 22.

[0049] Therefore, by arranging a plurality of through holes 221 at the support portion 22 of the filter net 2, the flow area of ​​air flowing from the front space of the through hole 221 to the rear space of the through hole 221 can be effectively increased, and the temperature difference between the air near the through hole 221 and the support portion 22 of the filter net 2 can be further reduced. At the same time, a plurality of through holes 221 are arranged on the support portion 22 of the filter net 2, which can reduce the adhesion area of ​​condensation, thereby further reducing the generation and dripping of condensation on the support portion 22 of the filter net 2.

[0050] In one embodiment of the present invention, Figure 5 As shown, the through hole 221 is a long strip-shaped hole extending from the filter portion 21 to the support portion 22 .

[0051] For example, the through hole 221 on the support part 22 of the filter 2 has a semicircular shape at the upper and lower parts and a rectangular shape at the middle part. The through hole 221 is in an elongated shape and extends from the filter part 21 to the support part 22 of the filter 2.

[0052] Therefore, by setting the through hole 221 on the support part of the filter 2 to be long strip, the opening area of ​​a single through hole 221 can be effectively increased, thereby effectively increasing the flow area of ​​air flowing from the front space of the through hole 221 to the rear space of the through hole 221, thereby improving the fluidity of air flowing from the front space of the through hole 221 to the rear space of the through hole 221, and further avoiding the liquefaction of water vapor in the air into condensation. At the same time, the long strip through hole 221 is set on the support part 22 of the filter 2, which can reduce the adhesion area of ​​condensation, thereby further reducing the generation and dripping of condensation on the support part 22 of the filter 2.

[0053] In one embodiment of the present invention, Fig. 9 As shown, a protruding rib 222 is provided on a surface of the support portion 22 which is away from the panel 13 in the thickness direction.

[0054] Specifically, a convex rib 222 is provided on the surface of the support portion 22 of the filter 2, which is away from the panel 13, and the convex rib 222 protrudes along the thickness direction of the support plate. Further, there can be multiple convex ribs 222, and they can be extended and arranged on the support portion 22 along the left-right direction and the up-down direction of the support portion 22. In particular, when the convex rib 222 encounters the through hole 221 on the support portion 22 in the extending direction, the convex rib 222 should be disconnected.

[0055] When the filter 2 is installed on the air conditioner indoor unit 100, one side of the rib 222 is connected to the side surface of the support portion 22 facing away from the panel 13, and the other side of the rib 222 is in contact with the side surface of the fixing frame 15 facing the panel 13. When the air conditioner indoor unit 100 is in operation, the support portion 22 of the filter 2 can be in contact with the side surface of the fixing frame 15 facing the panel 13 through the rib 222.

[0056] In this embodiment, by providing a convex rib 222 on the side surface of the support portion 22 away from the panel 13, it is ensured that when the air conditioner indoor unit 100 is in operation, the support portion 22 of the filter 2 can be abutted against the side surface of the fixing frame 15 facing the panel 13 through the convex rib 222, thereby fixing the support portion 22 of the filter 2 and the through hole 221 on the support portion 22, so that the air on both sides of the through hole 221 can be stably circulated through the through hole 221, thereby ensuring the circulation effect and reducing the noise when the air conditioner indoor unit 100 is in operation. In addition, the convex rib 222 can make the support portion 22 of the filter 2 have sufficient structural strength to ensure that the support portion 22 can withstand a certain deformation, thereby increasing the durability of the support portion 22.

[0057] In one embodiment of the present invention, Figure 5 As shown, the support portion 22 is provided with a clamping portion 223 , and the clamping portion 223 is suitable for being engaged with the clamping protrusion 131 on the panel 13 to fix the filter screen 2 .

[0058] For example, the clamping portion 223 is provided on the support portion 22 of the filter 2. Further, there may be a plurality of clamping portions 223, which are arranged at intervals along the left-right direction; there may be two clamping portions 223, which are respectively arranged at the left and right ends of the support portion 22 of the filter 2. The clamping protrusion 131 is provided on the inner surface of the panel 13 of the air conditioner indoor unit 100, and the upper surface of the clamping protrusion 131 is a guide inclined surface 1311, which is an inclined surface inclined from top to bottom and backward.

[0059] When the filter 2 is installed on the air conditioner indoor unit 100, the guide slope 1311 of the clamping protrusion 131 abuts against the upper end of the clamping portion 223, and the clamping portion 223 is engaged with the clamping protrusion 131 to fix the support portion 22 of the filter 2. When the filter 2 of the air conditioner indoor unit 100 is removed, the upper end of the clamping portion 223 slides along the guide slope 1311 of the clamping protrusion 131 and finally separates, and the filter 2 can be taken out for cleaning under the action of gravity. Through the abutment, engagement and sliding separation of the guide slope 1311 and the upper end of the clamping portion 223, the installation and removal of the filter 2 can be achieved, reducing the difficulty of assembly and improving the assembly efficiency.

[0060] Thus, by providing the holding portion 223 on the support portion 22 and the holding protrusion 131 on the panel 13, when the filter 2 is installed on the air conditioner indoor unit 100, the holding portion 223 and the holding protrusion 131 can be engaged to prevent the filter 2 from falling off under the action of gravity, thereby fixing the filter 2. When the filter 2 is taken out, the holding portion 223 and the holding protrusion 131 can be separated, which facilitates the removal and cleaning of the filter 2.

[0061] In one embodiment of the present invention, Figure 5 As shown, the holding portion 223 is formed by a portion of the support portion 22 protruding from one side toward the other side along the thickness direction, and the holding portion 223 defines a holding groove on one side of the support portion 22 .

[0062] Specifically, a clamping portion 223 is formed on a portion of the surface of the side of the support portion 22 facing the panel 13, and protrudes from the side of the support portion 22 facing the panel 13 to the side of the support portion 22 away from the panel 13 along the thickness direction of the support portion 22. The clamping portion 223 forms a clamping groove on the side of the support portion 22 facing the panel 13. When the filter 2 is installed on the air-conditioning indoor unit 100, the clamping portion 223 and the clamping protrusion 131 are engaged in the clamping groove to fix the support portion 22 of the filter 2.

[0063] Thus, by providing a slot on the holding portion 223 on the side of the support portion 22 facing the panel 13, when the filter 2 is installed on the air conditioner indoor unit 100, the guide slope 1311 on the upper surface of the clamping protrusion 131 can abut against the upper end of the holding portion 223 in the slot, thereby preventing the filter 2 from falling off under the action of gravity. At the same time, one end of the rib 222 on the support portion 22 abuts against the side surface of the fixing frame 15 facing the panel 13, and the holding portion 223, the clamping protrusion 131, the rib 222 and the fixing frame 15 cooperate with each other to effectively fix the filter 2.

[0064] In one embodiment of the present invention, Figure 5-Figure 9As shown, the filter screen 2 further includes a flat plate portion 23. The flat plate portion 23 is connected to one end of the support portion 22 away from the filter portion 21 and is arranged perpendicular to the support portion 22. The side surface of the flat plate portion 23 away from the support portion 22 is suitable for forming the upper wall surface of the outlet end of the air duct 14.

[0065] Specifically, the flat plate portion 23 is disposed at the bottom of the filter screen 2, and the flat plate portion 23 is connected to the end of the support portion 22 that is away from the filter portion 21, and is perpendicular to the support portion 22. A pressing portion 231 and a word reminding to press are disposed on the surface of the flat plate portion 23 on the side away from the support portion 22. Further, the pressing portion 231 can be disposed at the middle position of the flat plate portion 23 along the left-right direction, and the shape of the pressing portion 231 can be a long strip, and the word reminding to press can be set to be a text surface highlight.

[0066] When removing the filter 2, the air guide plate is opened. Since the surface of the side of the flat plate portion 23 away from the support portion 22 constitutes the upper wall surface of the outlet end of the air duct 14, after opening the air guide plate, the flat plate portion 23 of the filter 2 can be directly seen at the air outlet 142, and the filter 2 can be removed through the flat plate portion 23. Specifically, at the air outlet 142, a highlighted reminder word "press" can be seen at the pressing part 231 of the flat plate portion 23. Pressing the pressing part 231 of the flat plate portion 23 bends and deforms upward, and the left and right ends of the flat plate portion 23 are deformed downward, and the value range of the deformation amount is 0 to 0.6 mm. At this time, the clamping parts 223 at both ends of the flat plate portion 23 move downward, and the clamping protrusions 131 of the panel 13 are separated from the clamping grooves of the clamping parts 223, and then the filter 2 can be taken out under the action of gravity for cleaning.

[0067] In this embodiment, the flat plate portion 23 of the filter 2 is provided so that the surface of the flat plate portion 23 on one side away from the support portion 22 constitutes the upper wall surface of the outlet end of the air duct 14, thereby ensuring the air outlet effect at the air outlet 142 end and increasing the aesthetic appearance of the air conditioner indoor unit 100. By providing the flat plate portion 23 and the pressing portion 231 and the pressing reminder words thereon, the filter 2 can be conveniently taken out for cleaning.

[0068] like Figure 1-Figure 4 As shown, the air conditioner indoor unit 100 according to the second embodiment of the utility model comprises: a housing 1 and a filter 2 according to the first embodiment of the utility model. The housing 1 is formed with an air duct 14 and an air inlet 141 and an air outlet 142 connected to the air duct 14; the filter 2 is removably arranged in the housing 1, the filter part 21 covers the air inlet 141, and the support part 22 extends to the position of the air outlet 142.

[0069] Specifically, the shell 1 of the air-conditioning indoor unit 100 includes a chassis 11, a face frame 12 and a panel 13, the air inlet 141 of the air-conditioning indoor unit 100 is arranged at the top position of the face frame 12, the shell 1 forms an air duct 14 for air circulation in its internal space, and the air outlet 142 of the air-conditioning indoor unit 100 is arranged between the front end of the chassis 11 and the lower end of the panel 13; the air-conditioning indoor unit 100 also includes an air guide component 3, a fan component 4 and an indoor heat exchanger, the air guide component 3 includes an air guide plate, the air guide plate is arranged at the air outlet 142 position for opening and closing the air outlet 142, the indoor heat exchanger is installed in the shell 1 and is located between the air inlet 141 and the fan component 4; the filter net 2 of the air-conditioning indoor unit 100 is removably arranged in the shell 1, the filter part 21 of the filter net 2 covers the air inlet 141 of the air-conditioning indoor unit 100, and the support part 22 of the filter net 2 extends to the air outlet 142 position of the air-conditioning indoor unit 100. Furthermore, a guide rail for the filter screen 2 may be provided on the inner wall surface of the housing 1 , and the filter screen 2 may be slidably mounted on the guide rail.

[0070] When the air conditioner indoor unit 100 is operated in a high temperature and high humidity environment, the air guide plate at the air outlet 142 is opened, and the wind wheel of the air conditioner indoor unit 100 rotates under the drive of the motor. Under the drive of the wind wheel, the air passes through the filter part 21 of the filter 2 from the air inlet 141 of the air conditioner indoor unit 100. The filter part 21 can filter out tiny particles in the air. The filtered air enters the air duct 14 of the air conditioner indoor unit 100, and is finally discharged through the air outlet 142 under the drive of the wind wheel. Part of the air escapes to the front space of the support part 22 of the filter 2 after rotating along the wind wheel, and can flow into the rear space of the support part 22 of the filter 2 through the through hole 221 on the support part 22, and finally flows to the air outlet 142 through the structural gap of the air conditioner indoor unit 100.

A second groove portion 17 that is recessed upward is formed on the lower surface of the fixing bracket 15, and the second groove portion 17 extends left and right, and the second groove portion 17 penetrates the front edge of the fixing bracket 15 forward. The first groove portion 16 and the second groove portion 17 together form a receiving groove. When the filter 2 is installed on the air conditioner indoor unit 100, the flat plate portion 23 of the filter 2 is located in the receiving groove, and the support portion 22 of the filter 2 is located between the fixing bracket 15 and the lower end of the panel 13.

[0075] When the filter 2 needs to be removed for cleaning, the filter 2 can be removed by sliding down under the action of gravity by pressing the pressing portion 231 of the flat plate portion 23. When the air conditioner indoor unit 100 is operated in a high temperature and high humidity environment, the air escaping into the front space of the support portion 22 of the filter 2 flows into the rear space of the support portion 22 through the through hole 221 on the support portion 22, and finally flows to the air outlet 142 through the structural gap between the fixing frame 15 and the flat plate portion 23, and is discharged into the indoor space.

[0076] Therefore, by providing the flat plate portion 23 of the filter 2, the filter 2 can be conveniently taken out for cleaning; by providing the fixing frame 15, the lower part of the panel 13 of the air-conditioning indoor unit 100 and the lower part of the fixing frame 15 can form a receiving groove together, and the flat plate portion 23 of the filter 2 is placed in the receiving groove. At the same time, a circulation channel for escaping air can be formed between the fixing frame 15 and the flat plate portion 23 to ensure smooth circulation of the escaping air.
