Description

TECHNICAL FIELD

[0001] The utility model relates to an air conditioner capable of more easily assembling and disassembling a filter assembly. BACKGROUND

[0002] Generally, an air conditioner is a device for maintaining air in a prescribed space in an optimal state according to a purpose. For example, in summer, it can function to relatively lower the air temperature in a room by discharging heat in the room to the outside. In winter, it relatively increases the temperature of air discharged from the air conditioner, thereby relatively increasing the temperature in the room compared to the temperature outside. Alternatively, it purifies air in a prescribed space and then discharges the air into the space.

[0003] In the air conditioner as described above, in the case of a wall-mounted air conditioner, indoor air is sucked through a suction port and is discharged to the indoor through a discharge port after passing through a heat exchanger in a cover body. Thus, air flow generated using a cross-flow fan is provided to the indoor after sequentially passing through the suction port, the heat exchanger, a flow guide, and the discharge port, thereby managing the indoor air.

[0004] In order to filter foreign matter in air sucked from the indoor, a filter assembly is provided at the suction port of the aforementioned wall-mounted air conditioner. With respect to such an air conditioner provided with a filter assembly, various disclosures are made in Patent No. 10-2015-0084370, Patent No. 10-2018-0008063, Patent No. 10-2020-0095956, Patent No. 10-2008-0070891, and Patent No. 10-2010-0043992, etc.

[0005] On the other hand, in the case of a wall-mounted air conditioner, the suction port is formed at the front surface or the top surface of the cover body, and the discharge port is formed at the front surface or the bottom surface of the cover body.

[0006] Recently, the suction port is formed at the top surface of the cover body to minimize the exposure amount of the suction port of the wall-mounted air conditioner.

[0007] However, the wall-mounted air conditioner is installed at an upper portion (close to the ceiling) of a wall surface in a room, and thus, in the case of a structure in which the suction port is formed at the top surface, there is a problem in that it is difficult to install or detach the filter assembly.

[0008] That is, since the filter assembly is located at a position that is not visible to the user, it is difficult for the user to install or detach the filter assembly.

[0009] In addition, in order to stably install the cover, the frame body of the conventional filter assembly is provided with a plurality of hooks on the peripheral frame surface, and the inner side portion is formed in a lattice type structure having a plurality of openings. Thus, in the conventional art, a portion (gripping portion) for gripping the frame body is provided on each of the front side portions of the frame body.

[0010] However, although the plurality of gripping portions are provided, they are located at a position outside the user's field of view, so it is difficult for the user to correctly recognize the positions of the gripping portions, and thus there is a problem of dissatisfaction caused by separation of the filter assembly.

[0011] In addition, in the conventional filter assembly, a protrusion protruding rearward from the rear surface of the frame body is formed, and a groove for the protrusion to penetrate is formed in the rear surface of the opening of the suction inlet formed in the top surface of the cover, so that the coupling of the cover to the frame body can be stably achieved.

[0012] However, the coupling portions of the cover and the frame body are also located at a position outside the user's field of view, so the operation of coupling the protrusion to the groove becomes difficult, and thus there is a problem that the filter assembly cannot be correctly coupled, and a part of the filter assembly is misaligned.

[0074] ​Embodiments of the present application will be described with reference to the accompanying drawings. Note that, when giving reference numerals to the components of each drawing, the same components are given the same reference numerals as much as possible, even if the components are shown in different drawings.

[0075] In addition, in describing the embodiments of the present application, detailed description of related well-known structures or functions will be omitted when it is determined that the omitted description will not contribute to the understanding of the embodiments of the present application.

[0076] In addition, in describing the components of the embodiments of the present application, the terms first, second, A, B, (a), (b), and the like can be used. Such terms are used only to distinguish one component from another component, and do not limit the nature or order or sequence of the corresponding components. In the case where one component is described as being "connected", "coupled", or "contacted" with another component, it should be understood that the component can be directly connected or contacted with the other component, but can also be "connected", "coupled", or "contacted" with the other component with yet another component in between.

[0077] The air conditioner of the present application relates to a filter assembly for removing foreign matter in inhaled air. In particular, in the present application, a user is allowed to correctly hold and easily separate without directly seeing the part for which a person holds for separating the filter assembly.

[0078] To this end, hereinafter, the air conditioner of the embodiments of the present application will be described in further detail with reference to the accompanying drawings. Figures 1 to 15 , the air conditioner of the embodiments of the present application will be described in further detail with reference to the accompanying drawings.

[0079] The illustrated Figure 1 shows the internal structure of the air conditioner of the embodiments of the present application.

[0080] As shown in the drawings, the air conditioner of the embodiments of the present application can include a cover body 10.

[0081] The cover body 10 can define the appearance of the air conditioner. For example, the cover body 10 can become a part that forms the appearance of the wall-mounted air conditioner.

[0082] The cover body 10 can provide the front surface, the top surface, and the two side surfaces of the air conditioner.

[0083] A part of the appearance of the air conditioner can be provided as a different component. For example, the back surface 11 in the appearance of the air conditioner can be formed to have a flow guide 33. The bottom of the appearance of the air conditioner can be formed as a bottom plate 15 that is provided separately from the cover body 10. The bottom plate 15 can be installed to close the open bottom surface of the cover body 10.

[0084] Figure 2 and Figure 12 indicates the relationship between the cover body and the filter assembly in the air conditioner according to an embodiment of the present application.

[0085] As shown in the drawing, the cover body 10 is provided with a suction port 101. The suction port 101 can be defined as an inlet through which air in the indoor space outside the cover body 10 flows into the inside of the cover body 10.

[0086] The suction port 101 can be provided at one side of the cover body 10. For example, the suction port 101 can be provided at the top surface of the cover body 10.

[0087] Such a suction port 101 can be formed by opening the entire top surface portion of the cover body 10, or can be formed by opening only a portion of the top surface of the cover body 10. Although not shown, the suction port 101 can be formed at both side surfaces or the front surface or the back surface of the cover body 10, or can be formed at one of the above-mentioned surfaces.

[0088] The suction port 101 is formed by opening the top surface of the cover body 10 except for the frame portion (the inside of the frame).

[0089] As shown in Figure 3 and Figure 5 In the cover body 10, a placement table 110 is formed so as to place the filter assembly 20 described later. The placement table 110 is formed at an upper end portion in the inner surface of the cover body 10.

[0090] The placement table 110 is located at a position lower than the top surface of the cover body 10 in the inner surface of the cover body 10. The placement table 110 is formed at a position spaced apart from the top surface of the cover body 10 by a height corresponding to the thickness of the filter assembly 20. Thus, in the case where the filter assembly 20 is placed on the placement table 110, the top surface of the filter assembly 20 is maintained at the same height as the top surface of the cover body 10.

[0091] The placement table 110 is formed to protrude along the inner surface of the cover body 10. The protruding distance of the placement table 110 is formed to be equal to or greater than the width of each of the peripheral frames 211, 212, 213 constituting the filter assembly 20. That is, in the case where the filter assembly 20 is installed in the cover body 10, the entire bottom surface of each of the peripheral frames 211, 212, 213 of the filter assembly 20 is placed on the placement table 110 of the cover body 10. In this case, the bottom surface of each of the peripheral frames 211, 212, 213 of the filter assembly 20 is blocked by the placement table 110.

[0092] A plurality of connecting frames 120 may be connected to the placement platform 110. For example, the front end and rear end of the connecting frames 120 are respectively connected to the placement platform 110 located on the front side (the indoor side when viewing the enclosure from a plane) and the placement platform 110 located on the rear side (the wall side when viewing the enclosure from a plane). As a result, the rear periphery of the top surface of the enclosure 10 can be maintained without bending or deformation.

[0093] The connecting frame 120 also serves to support the bottom surface of the filter assembly 20. The bottom surface of the filter assembly 20 is supported by the connecting frame 120, thereby preventing sagging of the inner parts of the filter assembly 20. For this purpose, the connecting frame 120 may have a curved or inclined surface.

[0094] The enclosure 10 may provide outlets 102 and 103. The outlets 102 and 103 may be defined as outlets for discharging air flowing within the enclosure 10 into the indoor space.

[0095] Such outlets 102 and 103 may include a front outlet 102 provided on the lower front of the cover 10. The front outlet 102 may be defined as a portion that expels air forward. The front outlet 102 may also be configured to extend long along the left and right sides of the front of the cover 10 when viewed from the front.

[0096] The discharge ports 102 and 103 may include bottom discharge ports 103 provided on the bottom surface of the cover 10.

[0097] like Figure 1 As shown, the bottom outlet 103 can be located on the front side of the bottom surface of the cover 10. The bottom outlet 103 can be located adjacent to the front outlet 102. Thus, air can be expelled towards the front and lower part of the cover 10 through the front outlet 102 and the bottom outlet 103.

[0098] Although not shown in the figure, the discharge outlets 102 and 103 may only be provided as the front discharge outlet 102 or only as the bottom discharge outlet 103, or they may be additionally provided on at least one of the various walls of the cover 10.

[0099] A heat exchanger 31 may be provided inside the enclosure 10. The heat exchanger 31 may be defined as a device or structure that allows heat exchange between the refrigerant in the heat exchange cycle and the air drawn in from the indoor space through the intake 101.

[0100] A refrigerant of a heat exchange cycle flows in the heat exchanger 31. Thereby, the refrigerant passing through the heat exchanger 31 and the air sucked from the indoor through the suction port 101 heat-exchange with each other, and then is supplied to the indoor through the discharge ports 102, 103, so that the temperature of the indoor air can be managed.

[0101] The heat exchanger 31 can be configured to surround an outer surface of the driving fan 32. For example, as shown in Figure 1 The heat exchanger 31 can be configured to surround an upper side portion of the driving fan 32.

[0102] Next, the air conditioner according to an embodiment of the present application can include a driving fan 32 which forms an air flow.

[0103] The driving fan 32 can generate an air flow passing through the suction port 101 and the discharge ports 102, 103 formed in the cover body 10. That is, the driving fan 32 generates an air flow to suck the air in the indoor through the suction port 101 and discharge it through the front discharge port 102 or the bottom discharge port 103.

[0104] The driving fan 32 can use a cross-flow fan (for example, a cross-flow fan). That is, the driving fan 32 can be formed to be separated by a plurality of blades and configured in a cylindrical shape.

[0105] Next, the air conditioner according to an embodiment of the present application can include a flow guide 33.

[0106] The flow guide 33 can be defined as a portion or structure which guides the flow of the air passing through the driving fan 32.

[0107] The flow guide 33 can be manufactured separately from the cover body 10 and disposed at the back surface of the cover body 10. Alternatively, the flow guide 33 can also form the back surface of the cover body 10. Although not shown, the flow guide 33 can also be integrally formed with the back surface of the cover body 10.

[0108] The flow guide 33 provides a space in which the driving fan 32 is disposed. The space formed by the flow guide 33 can provide a portion of the space in which the driving fan 32 is disposed.

[0109] Next, the air conditioner according to an embodiment of the present application includes a filter assembly 20.

[0110] The filter assembly 20 is a device or structure provided to filter foreign substances from the indoor air sucked through the suction port 101 of the cover body 10.

[0111] The filter assembly 20 can be installed to block the suction port 101 of the cover body 10, and can be composed of a frame body 21 and a filter 22.

[0112] The frame body 21 forms the appearance of the filter assembly 20.

[0113] The filter 22 functions to filter foreign substances in air flowing into the cover body 10 through the frame body 21. The filter 22 can be provided at the bottom surface of the frame body 21, and can be formed as a mesh blocking the opening formed in the frame body 21. The filter 22 is provided in a mold at the time of injection molding of the frame body 21, thereby being formed integrally with the frame body 21.

[0114] The frame body 21 can be formed in the shape of a polygonal frame. For example, the frame body 21 can be formed in the shape of a quadrangular frame.

[0115] The frame body 21 has a plurality of peripheral frames 211, 212, 213. For example, the frame body 21 can include a first peripheral frame 211 forming a front side peripheral portion, a second peripheral frame 212 forming a rear side peripheral portion, and two third peripheral frames 213 forming both side peripheral portions.

[0116] The first peripheral frame 211 and the second peripheral frame 212 are spaced apart in the front and rear directions and are arranged in parallel, and one end of the two third peripheral frames 213 is connected to one end of the first peripheral frame 211 and the other end is connected to the other end of the second peripheral frame 212. The two third peripheral frames 213 are spaced apart in the left and right directions and are arranged in parallel.

[0117] Each of the peripheral frames 211, 212, 213 is formed in a double wall structure having a front surface and a back surface when viewed in cross section. For example, each of the peripheral frames 211, 212, 213 includes a first wall 201 provided as an outer wall and a second wall 202 provided as an inner wall.

[0118] The first wall 201 is provided as an outer wall, and the second wall 202 is provided as an inner wall. The outer wall is a wall surface facing the outside of the filter assembly 20, and the inner wall is a wall surface facing the opposite peripheral frame 211, 212, 213.

[0119] Each of the peripheral frames 211, 212, 213 can further include a third wall 203 provided as an outer wall and connecting the first wall 201 and the second wall 202. The third wall 203 can be provided as a top surface of the peripheral frame 211, 212, 213. The third wall 203 can be formed to block the entire upper portion between the first wall 201 and the second wall 202 or to block only a portion of the upper portion between the first wall 201 and the second wall 202.

[0120] The first wall 201 can be formed longer than the second wall 202 in the up-and-down direction. For example, the lower end of the second wall 202 can be formed shorter than the lower end of the first wall 201 with reference to the third wall 203.

[0121] The lower portion between the first wall 201 and the second wall 202 (between the lower end of the first wall and the lower end of the second wall) can be open.

[0122] On the other hand, the filter assembly 20 constituting an air conditioner according to an embodiment of the present application proposes that a handle groove 23 is formed in at least one of the peripheral frames 211, 212, 213 of the frame body 21. The handle groove 23 can be used as a portion for a user to hold when separating or combining the filter assembly 20 with the cover body 10.

[0123] In the related art, in order to separate the filter assembly 20, a block-shaped handle portion 24 is formed at a portion of the connection frame 120. However, this block-shaped handle portion 24 is a structure that needs to be held and lifted with two fingers, and thus is difficult to use.

[0124] In particular, the filter assembly 20 is disposed on the top surface of the cover body 10, and thus a user cannot correctly recognize the position of the handle portion 24. Thus, separation of the filter assembly 20 inevitably becomes difficult.

[0125] In consideration of this, an embodiment of the present application proposes a structure in which at least one finger is hooked to a portion of the filter assembly 20 and lifted, thereby enabling easy separation. That is, the finger is hooked to the filter assembly 20 and lifted, thereby enabling easy separation of the filter assembly 20 from the cover body 10.

[0126] In consideration of this, the handle groove 23 in which a finger can be hooked and lifted is formed in the filter assembly 20. The handle groove 23 is formed to have an up-and-down height (vertical direction side length) and a left-and-right width (horizontal direction side length) into which at least one finger can be inserted. Preferably, the handle groove 23 is formed to have a left-and-right width into which at least two fingers can be inserted.

[0127] The handle groove 23 can be provided at least one. The at least one handle groove 23 is preferably formed at a position which can be easily recognized by a user. To this end, the at least one handle groove 23 is formed at a central side portion of the first peripheral frame 211 constituting the frame body 21.

[0128] More specifically, the at least one handle groove 23 can be formed at the second wall 202 of the first peripheral frame 211. That is, the at least one handle groove 23 can be formed at a central side portion of the second wall 202. Thereby, even if the filter assembly 20 is located at a top surface of an air conditioner and is not visually recognized, a user can correctly recognize the approximate position of the handle groove 23.

[0129] In particular, the handle groove 23 is formed at the second wall 202, so a user can hold the handle groove 23 snugly. Thereby, an operation of separating the filter assembly 20 from the cover 10 can be more easily performed.

[0130] Although not illustrated, the handle groove 23 can be formed by protruding a portion of the second wall 202 toward the first wall 201. That is, the handle groove 23 can be formed in a structure in which a portion of the second wall 202 is recessed.

[0131] However, in order to form the handle groove 23 recessed from the second wall 202, an additional mold for the formation of the handle groove 23 is required. That is, considering that the frame body 21 of the filter assembly 20 is formed through an injection molding work, it is difficult to form a recessed portion in a direction perpendicular to a direction (an up-and-down direction when the filter assembly is viewed from the front) in which the mold is separated, and must be formed using an additional mold (or a process) after the injection molding.

[0132] In consideration of this, the handle groove 23 of the second wall 202 of the embodiment of the present application preferably opens a portion of the second wall 202 and can use the portion opened in this manner as the handle groove 23, rather than being formed recessed toward the first wall 201. That is, by cutting a portion of the second wall 202 to be opened, the opened portion is used as the handle groove 23.

[0133] In the case in which the handle groove 23 is formed by opening a portion of the second wall 202, an inner surface (a surface facing the second wall) of the first wall 201 can be provided as an inner surface of the handle groove 23.

[0134] A bottom surface of the handle groove 23 is opened to a bottom portion together with a space between the first wall 201 and the second wall 202. Thereby, after the injection molding, the mold can be smoothly moved to a lower portion.

[0135] In the case in which the bottom surface of the handle groove 23 is formed to be open, a portion of the filter 22 attached to a bottom surface of the frame body 21 can be exposed inside the handle groove 23.

[0136] In consideration of this, a structure for preventing a portion of the filter 22 from being exposed through the handle groove 23 from the second wall 202 when the filter 22 is integrally injection-molded with the frame body 21 can be provided. To prevent the exposure of the filter 22, a lower end rib 25 can also be formed in the second wall 202.

[0137] The lower end rib 25 is formed in front of the lower end of the handle groove 23 in the front surface of the second wall 202, thereby blocking the lower end of the handle groove 23. At this time, the back surface of the lower end rib 25 is formed to be spaced apart in the forward direction as much as or more than the front surface of the second wall 202.

[0138] Since the bottom surface of the handle groove 23 is formed to be open, the first wall 201 of the portion in which the handle groove 23 is formed can be relatively weak against bending deformation. In consideration of this, at least one reinforcing rib 26 for preventing the bending deformation of the first wall 201 can be further provided in the handle groove 23 at the corresponding portion. Such a reinforcing rib 26 can be formed to connect the back surface of the first wall 201 and the lower end rib 25.

[0139] On the other hand, the handle groove 23 can have side walls. For example, partition walls 231 can be formed in both sides of the handle groove 23, respectively. The partition walls 231 can be formed to block between the first wall 201 and the second wall 202 of the first peripheral frame 211. Thereby, it is possible to prevent the indoor air flowing into the handle groove 23 from flowing to both sides of the handle groove 23 in the space between the first wall 201 and the second wall 202.

[0140] The third wall 203 constituting the first peripheral frame 211 can be provided as a top surface in the handle groove 23.

[0141] A third protrusion 27 can be additionally formed in the top surface of the entrance side of the handle groove 23. The third protrusion 27 can be formed to protrude downward from the top surface in the handle groove 23. Due to the additional formation of such a third protrusion 27, it is possible to prevent the problem of the finger slipping out of the handle groove 23 during the process of inserting the finger into the handle groove 23 and lifting the filter assembly 20.

[0142] In addition, in the case where the handle groove 23 is formed as an open hole, the air in the room can not pass through the filter but directly flow into the cover body 10 through the open bottom surface between the first wall 201 and the second wall 202 after passing through the handle groove 23. That is, it is possible to flow into the cover body 10 without filtering foreign substances from the indoor air.

[0143] Thus, the open bottom surface between the first wall 201 and the second wall 202 is blocked by the placement table 110 formed in the cover 10. That is, the open bottom surface between the first wall 201 and the second wall 202 at the portion where the handle groove 23 is formed can be placed on the placement table 110, thereby being closed.

[0144] Hereinafter, the attachment and detachment process of the filter assembly 20 of the air conditioner according to the foregoing embodiment of the present application will be described in further detail.

[0145] First, when the air conditioner is operated, the filter assembly 20 filters foreign substances in the air drawn into the cover 10 in a state of being installed in the cover 10.

[0146] That is, the air flow generated by the driving of the driving fan 32 flows into the cover 10 after passing through the filter assembly 20, and then performs heat exchange through the heat exchanger 31, and then is supplied to the indoor through the discharge ports 202 and 203 under the guidance of the flow guide 33. In this process, the foreign substances are filtered by the filter 22 in the process of passing through the filter assembly 20, and the clean air in which the foreign substances are filtered is supplied to the indoor again after heat exchange.

[0147] In the process of passing through the filter assembly 20, the indoor air can flow into the first wall 201 and the second wall 202 of the first peripheral frame 211 through the handle groove 23.

[0148] However, both sides in the handle groove 23 are blocked by the partition wall 231, the upper side in the handle groove 23 is blocked by the third wall 203, and the lower side in the handle groove 23 is blocked by the placement table 110. Thus, even if the indoor air flows into the handle groove 23, the problem that the air flows to the cover 10 without passing through the filter 22 can be prevented.

[0149] Next, the process of separating the filter assembly 20 from the cover 10 will be described.

[0150] In the case of separating the filter assembly 20 from the cover 10, the user inserts a finger into the handle groove 23.

[0151] Since the filter assembly 20 is located at the top surface of the cover 10, the user cannot visually see the handle groove 23. However, the handle groove 23 is formed at the central portion of the second wall 202 of the first peripheral frame 211 constituting the filter assembly 20, and the user can observe the front surface of the cover 10 and roughly recognize the central portion. Thus, the user can know the approximate position even if the handle groove 23 is not seen, and thus can correctly insert the finger into the handle groove 23.

[0152] In particular, the second wall 202 of the first peripheral frame 211 is located at the rear when viewed from the user's position (front), so that the user can grip the handle groove 23 when inserting a finger into the handle groove 23 of the second wall 202. Thus, the user can easily lift the filter assembly 20 with their finger inserted into the handle groove 23.

[0153] Furthermore, when the user inserts their finger into the handle groove 23, there is a risk that the finger may slip and detach from the handle groove 23 during the process of lifting the filter assembly 20. However, since a third protrusion 27 is formed on the top surface of the inlet side of the handle groove 23, the problem of the finger slipping and detaching from the handle groove 23 can be prevented.

[0154] Thus, even if the filter assembly 20 constituting the air conditioner of this invention is located outside the user's field of vision, the user can easily grasp the position of the handle groove 23 because a handle groove 23 is formed on the central side of the first peripheral frame 211.

[0155] Furthermore, in the filter assembly 20 constituting the air conditioner of this utility model, the handle groove 23 is formed by a portion of the second wall 202 of the open first peripheral frame 211, thereby allowing easy mold separation during the injection molding of the filter assembly 20.

[0156] Meanwhile, partition walls 231 are added to both sides of the handle groove 23, and the bottom surface of the handle groove 23 (the open part between the first wall and the second wall) is placed on the placement platform 110 of the cover 10 and sealed. This prevents indoor air from flowing directly into the cover 10 through the handle groove 23.

[0157] In addition, the air conditioning mechanism of this utility model allows the filter assembly 20 to be separated from the cover 10 more easily by inserting a finger into the handle groove 23 and lifting it, compared to the method of grasping and lifting with two fingers.

[0158] On the other hand, in the air conditioner of this utility model, in addition to the aforementioned embodiments, various modifications or variations are also possible. These embodiments are described below by way of examples.

[0159] As an example of the air conditioner of this utility model, such as Figure 6 and Figure 8 As shown, it can also provide a structure that allows the user to feel the inner surface of the handle groove 23 by touch.

[0160] For example, at least one second protrusion 232 may be formed on the inner surface of the handle groove 23 of the filter assembly 20. That is, the user can feel the second protrusion 232, thereby recognizing that a finger is correctly inserted into the handle groove 23.

[0161] The second protrusions 232 can be formed on the inner surface of the first wall 201 provided as the inner surface of the handle groove 23. That is, the inner surface of the first wall 201 facing the handle groove 23 can be formed with a plurality of second protrusions 232. The second protrusions 232 can be defined as the concavo-convex members formed on the first wall 201.

[0162] As another example of the air conditioner according to the present application, a structure for restricting the filter assembly 20 to prevent the filter assembly 20 from being accidentally separated from the cover 10 can be further provided.

[0163] For example, as shown in FIGS. 1 to 3, the filter assembly 20 can be formed to provide a hook member 28 so that the filter assembly 20 and the cover 10 can be restricted from each other. Figure 3 、 Figure 5 and Figure 7 As shown in FIGS. 1 to 3, the filter assembly 20 can be formed to provide a hook member 28 so that the filter assembly 20 and the cover 10 can be restricted from each other.

[0164] The hook member 28 can be formed on the first wall 201, in which case, a hooking portion 281 to which the hook member 28 is hooked can be formed on the inner surface of the cover 10. The hook member 28 and the hooking portion 281 can be formed at positions opposite to each other, and can be provided in two or more, respectively. Thus, the filter assembly 20 can be prevented from being accidentally separated from the cover 10 in a state where the filter assembly 20 is installed in the cover 10.

[0165] The hooking portion 281 can be a portion protruded on the inner surface of the cover 10 or a top surface of the cover (a portion where the suction inlet is formed) can be defined as the hooking portion 281.

[0166] Meanwhile, the hook member 28 can be formed to be elastically deformable by cutting at least a portion of the first wall 201. Thus, even if a user lifts the filter assembly 20 with a small force, the filter assembly 20 can be smoothly separated from the cover 10.

[0167] As still another example of the air conditioner according to the present application, a structure for preventing the filter assembly 20 from moving in a horizontal direction in a state where the filter assembly 20 is installed in the suction inlet 101 of the cover 10 can be further provided.

[0168] That is, the conventional filter assembly 20 is formed to have a size smaller than that of the suction inlet 101 (front-to-rear width and left-to-right width) so as to be smoothly installed in the suction inlet 101 of the cover 10. Thus, when air flow is generated, the filter assembly 20 can be moved or shaken in a state where the filter assembly 20 is installed in the cover 10.

[0169] In consideration of this, a structure for preventing the filter assembly 20 from moving is provided, so that the filter assembly 20 can be prevented from being shaken or the like.

[0170] For example, as shown in FIGS. 1 to 3, the filter assembly 20 can be formed to provide a hook member 28 so that the filter assembly 20 and the cover 10 can be restricted from each other. Figure 3and Figure 5 As shown, a plurality of first protrusions 130 may be formed on the cover 10 to contact the first wall 201 of the first peripheral frame 211. Each of the first protrusions 130 may be formed to protrude from the inner surface of the cover 10 toward the first wall 201.

[0171] As another example of the air conditioner of this utility model, the filter assembly 20 and the cover 10 can be connected to each other by magnetic force.

[0172] Therefore, a first attachment member 291 and a second attachment member 292 capable of being magnetically attached to each other can be provided on the outer surface of a certain peripheral frame 211, 212, 213 constituting the filter assembly 20 and the inner surface of the opposite cover 10. That is, as Figure 14 As shown, the various attachment members 291, 292 made of magnets can be provided corresponding to each other on the outer surfaces of the peripheral frames 211, 212, 213 and the inner surfaces of the cover 10, or a certain attachment member made of magnets (e.g., the first attachment member) and another attachment member made of metal plate (e.g., the second attachment member) can be provided corresponding to each other.

[0173] The filter assembly 20 may provide each of the attachment members 291, 292 and the aforementioned hook member 28 simultaneously, or it may provide only the attachment structure based on the attachment members 291, 292.

[0174] The first attachment member (magnet or metal plate) 291 may be provided only on the back side (outer surface of the first wall) of the second peripheral frame 212 constituting the filter assembly 20, or it may be provided on the back side (outer surface of the first wall) of the second peripheral frame 212 of the filter assembly 20 and on the outer surface (outer surface of the first wall) of a third peripheral frame 213. Alternatively, the first attachment member 291 may be provided on the outer surface of all peripheral frames 211, 212, and 213 of the filter assembly 20.

[0175] Each of the attachment members 291, 292 may also be provided on the bottom surface of a peripheral frame 211, 212, 213 and the top surface of the placement platform 110 of the cover 10, respectively.

[0176] For example, such as Figure 15 As shown, a first attachment member 291 can be provided on the bottom surface of a certain peripheral frame 211, 212, 213, and a second attachment member 292 can be provided on the top surface of the placement platform 110.

[0177] As another example of the air conditioner of this utility model, a structure can also be provided for users to more accurately identify the position of the handle groove 23 of the filter assembly 20.

[0178] For example, in the top surface of the frame body 21 (top surface of the first peripheral frame) constituting the filter assembly 20, a marking member 40 can be provided on the upper side of the handle groove 23.

[0179] The marking member 40 is a member capable of visually distinguishing the mark from other parts, and thus can be formed in a different color from other parts of the frame body 21 or formed to have a surface (e.g., a concave-convex surface) different from the surface (e.g., a flat surface) of the frame body 21.

[0180] The marking member 40 can be combined or adhered with the top surface of the frame body 21, or integrally formed with the frame body 21 by injection molding.

[0181] As another example of the air conditioner of the present application, although not illustrated, a marking member 40 for marking the position of the handle groove 23 can also be provided on the front surface of the cover 10.

[0182] In this case, the marking member 40 can be formed in a different color from other parts of the cover 10 to be visually distinguished from other parts, or can be formed to have a surface (e.g., a concave-convex surface) different from the surface (e.g., a flat surface) of the cover 10.

[0183] As another example of the air conditioner of the present application, a block-shaped handle portion 24 for separating the filter assembly 20 can also be formed on the top surface of the filter assembly 20. The block-shaped handle portion 24 can be formed in a structure that is gripped and lifted with two fingers, and the shape or position thereof can be formed the same as the block-shaped handle portion of the prior art formed on the filter assembly.

[0184] That is, with the additional provision of the block-shaped handle portion 24, together with the recessed structure of the handle groove 23, as a use for separating the filter assembly 20, the user can select to use.

[0185] As such, the air conditioner of the present application can be implemented in various forms.
