Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning, in particular to an air conditioner. Background Art

[0002] Existing air conditioner indoor units generally use an air duct structure with air inlet at the top and air outlet at the bottom. The filter assembly is installed in the slide groove of the middle frame, semi-enclosing the outer periphery of the heat exchanger to filter the air passing through the heat exchanger.

[0003] In the prior art, the front side of the middle frame is covered with a panel. When removing the filter assembly, the panel must be removed first to expose the filter assembly, and then the filter assembly can be removed from the middle frame. This makes the filter assembly difficult to disassemble and assemble. Utility Model Content

[0004] The problem solved by the utility model is that it is troublesome to disassemble and assemble the filter assembly of the existing air-conditioning indoor unit.

[0005] In order to solve the above problems, the present application provides an air conditioner that can facilitate users to remove the filter assembly.

[0006] The utility model provides an air conditioner, comprising a middle frame, a surface frame and a filter assembly;

[0007] The middle frame is provided with a track groove for assembling the filter assembly;

[0008] The surface frame is arranged on the middle frame, and a mounting opening is arranged on the surface frame corresponding to the track groove;

[0009] The filter assembly is installed in the track groove and partially exposed at the installation opening, and the filter assembly can be pulled out from the installation opening.

[0010] The present application provides a mounting opening at a position on the face frame corresponding to the middle frame track groove, and the filter assembly is installed in the middle frame track groove, with part of the filter assembly exposed outside the mounting opening. Thus, when removing the filter assembly, the user can directly pull the filter assembly from the track groove by pulling it out of the filter assembly from the position exposed outside the mounting opening. When installing the filter assembly, the user can insert the end of the filter assembly into the track groove through the mounting opening to install the filter assembly in the middle frame. Overall, the filter assembly can be disassembled and assembled without opening the panel, making disassembly and assembly of the filter assembly more convenient.

[0011] In an optional embodiment, the track groove has a downward opening;

[0012] The face frame is provided with a stepped surface, the stepped surface corresponds to the opening, and the mounting opening is provided on the stepped surface;

[0013] The filter assembly extends into the face frame from the installation opening and can be plugged into the track groove through the opening.

[0014] This application provides a stepped surface on the face frame, positioning the mounting opening on the stepped surface. This allows for better alignment between the mounting opening and the track slot opening. During filter assembly installation, the filter assembly's end extends through the mounting opening into the face frame and can be quickly inserted into the track slot. Furthermore, the stepped surface prevents the mounting opening from being visible from the front of the air conditioner indoor unit, enhancing the aesthetics of the unit.

[0015] In an optional embodiment, the face frame is provided with an air outlet, and the air outlet is configured to supply air into the room;

[0016] The installation port is communicated with the air outlet. When the filter assembly is removed, the air outlet can avoid the filter assembly so that the filter assembly can be pulled out from the installation port.

[0017] This application connects the installation port with the air outlet, so that the position of the air outlet can be used to avoid the filter assembly, allowing users to more conveniently pull out the filter assembly and insert the filter assembly into the track groove.

[0018] In an optional embodiment, a handle is provided at the bottom end of the filter assembly, and the handle is exposed at the installation opening.

[0019] The present application provides a handle at the bottom end of the filter assembly and makes the handle exposed so that the user can conveniently pull out the filter assembly through the handle when removing the filter assembly.

[0020] In an optional embodiment, a mounting groove is provided on the bottom wall of the filter assembly, a handle is provided in the mounting groove, and the handle is rotatably mounted in the mounting groove;

[0021] The handle specifically extends out of the mounting slot and is housed in the mounting slot;

[0022] The handle is exposed at the installation opening when in the unfolded state.

[0023] This application provides a mounting groove on the bottom wall of the filter assembly and a rotatable handle within the groove. To remove the filter assembly, the user first unfolds the handle and then uses it to pull the filter assembly outward. After the filter assembly is installed, the handle can be rotated and retracted into the mounting groove, allowing the front frame to shield the filter assembly from view, enhancing the aesthetics of the air conditioner.

[0024] In an optional embodiment, one of the filter assembly and the middle frame is provided with a snap-fit portion, and the other is provided with a snap-fit groove;

[0025] When the filter assembly is installed in the track groove, the clamping portion is clamped in the clamping groove.

[0026] By providing the clamping portion and the clamping groove, the clamping portion and the clamping groove are clamped to prevent the filter assembly from falling out of the installation opening.

[0027] In an optional embodiment, the filter assembly is provided with snap-fit grooves on both sides near the bottom width direction;

[0028] The middle frame is located at the bottom of the track groove, and a clamping portion is provided on both sides of the track groove;

[0029] When the filter assembly is installed in the track groove, the clamping portion is clamped in the clamping groove.

[0030] The present invention provides a clamping groove on both sides of the filter assembly near the bottom width direction, and the middle frame is located at the bottom of the track groove, and has clamping parts on both sides of the track groove, so that the filter assembly can be fixed. In addition, the clamping parts on both sides can also guide the end of the filter assembly when installing the filter assembly, making it easier to insert the filter assembly into the track groove.

[0031] In an optional embodiment, the filter assembly includes a filter frame, a filter and a connecting arm;

[0032] The connecting arm is mounted on the filter frame, and the connecting arm can slide relative to the filter frame between a first position and a second position. The top of the filter is connected to a position of the filter frame near the top, and the bottom of the filter is connected to the connecting arm. The clamping groove is provided on the connecting arm, and the clamping portion is provided on the middle frame.

[0033] When the connecting arm is in the first position, the connecting arm is located at the lower end of the filter frame, and the connecting arm pulls the filter to unfold so that the filter cover is located on one side of the filter frame;

[0034] When the connecting arm is in the second position, the connecting arm is located at the top end of the filter frame, and the connecting arm pulls up the bottom end of the filter assembly to fold the filter assembly in half;

[0035] When the filter assembly is installed in the track groove, the connecting arm is located in the first position, the clamping portion is clamped in the clamping groove, and the filter frame is clamped with the track groove, and the bottom end of the filter frame is exposed at the installation opening;

[0036] Pulling the filter frame outward can move the connecting arm from the first position to the second position relative to the filter frame; after the connecting arm moves to the second position, the filter frame is released from the track groove, and then the filter frame is pulled outward, the filter frame can drive the connecting arm to move so that the clamping part disengages from the clamping groove, and is removed from the installation port together with the filter frame.

[0037] The present invention connects the top of the filter to the top of the filter frame. A connecting arm is movably mounted on the filter frame, and the bottom of the filter assembly is connected to the connecting arm. When the filter frame slides to a first position at the bottom of the filter frame, the connecting arm can pull the filter assembly outward, allowing the filter cover to be positioned on one side of the filter frame, thereby filtering dust during use. When removing the filter assembly, the connecting arm has a snap-in slot. When removing the filter assembly, the user pulls the filter frame outward. However, since the snap-in portion is locked in the snap-in slot, the connecting arm remains stationary, allowing only the filter frame to move outward. During the outward movement of the filter frame, the connecting arm moves relative to the filter frame from the first position to the second position, folding the filter in half. This folds the windward side of the filter inward, preventing dust from falling from the filter when the filter assembly is removed. Furthermore, when cleaning the filter assembly, the connecting arm drives the filter to unfold and fold, preventing the filter and the filter frame from interfering with each other, making cleaning the filter assembly easier.

[0038] In an optional embodiment, the track groove includes a first track groove section and a second track groove section connected in sequence, the first track groove section is arranged near the installation opening, the first track groove section gradually increases in the direction of the installation opening, and the width of the second track groove section corresponds to the thickness of the filter frame;

[0039] The clamping portion is arranged below the first track groove section;

[0040] When the filter assembly is installed in the track groove, the top of the filter frame is inserted into the second track groove section by the first track groove section, the connecting arm is located below the first track groove section, and both sides of the filter in the width direction are in contact with the filter frame under the action of the side walls of the second track groove section. The filter frame is clamped against the side walls of the second track groove section under the action of the clamping part;

[0041] The filter frame is pulled outward, and when the connecting arm moves to the second position relative to the filter frame, the top end of the filter frame moves into the second track groove section, so that the filter frame and the track groove are released from the engagement.

[0042] The present invention provides a method for securing the filter assembly by configuring the track groove as a first track groove section and a second track groove section, with the width of the second track groove section corresponding to the thickness of the filter frame. This allows the clamping portion to engage the clamping groove of the connecting arm when the filter frame is inserted into the second track groove section, applying a forward thrust to the connecting arm and the filter frame, causing the filter frame to abut against the front sidewall of the second track groove section, thereby securing the filter assembly. Furthermore, the first track groove section is configured to gradually increase in width toward the installation opening. When the user pulls the end of the filter frame outward to the first track groove section, the gradually increasing width of the first track groove section creates space for the filter frame and the connecting arm to move forward, facilitating the clamping portion to disengage from the clamping portion, allowing the filter frame and the connecting arm to be removed from the installation opening. Furthermore, the width of the second track groove section is configured to correspond to the thickness of the filter frame. This allows the front sidewall of the second track groove section to exert pressure on the filter when the filter assembly is reinstalled in the track groove, causing the widthwise sides of the filter frame to mate with the widthwise sides of the filter frame.

[0043] In an optional embodiment, a first limiting boss and a fixing structure are provided on the top of the filter frame, and a second limiting boss is provided on the bottom end of the filter frame;

[0044] The connecting arm is provided with a matching structure;

[0045] When the connecting arm is in the second position, the connecting arm abuts against the first limiting boss, and the fixing structure cooperates with the matching structure to keep the connecting arm in the second position;

[0046] When the connecting arm is in the first position, the connecting arm abuts against the second limiting boss, and the connecting arm can move between the first limiting boss and the second limiting boss.

[0047] The first and second limiting bosses are provided in this application to limit the range of movement of the connecting arm and prevent the connecting arm from dislodging from both ends of the filter frame. Furthermore, the fixing structure and the matching structure are provided to maintain the connecting arm in the second position when the connecting arm is in the second position, preventing the connecting arm from moving downward under the action of gravity when the filter assembly is removed.

DETAILED DESCRIPTION

[0064] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0065] Please refer to Figures 1 to 3 The present invention provides an air conditioner 100, which includes a middle frame 110, a surface frame 130 and a filter assembly 150. The middle frame 110 is provided with an air inlet. The middle frame 110 is provided with a track groove 111 for assembling the filter assembly 150 corresponding to the air inlet. The surface frame 130 is provided on the middle frame 110. The surface frame 130 is provided with a mounting opening 131 corresponding to the track groove 111. The filter assembly 150 is installed in the track groove 111 and is partially exposed at the mounting opening 131. The filter assembly 150 can be pulled out from the mounting opening 131.

[0066] In this embodiment, a mounting opening 131 is provided on the face frame 130 at a position corresponding to the track groove 111 of the middle frame 110. The filter assembly 150 is installed within the track groove 111 of the middle frame 110, with a portion exposed outside the mounting opening 131. This allows the user to remove the filter assembly 150 by simply pulling it from the track groove 111 at the position exposed by the mounting opening 131. To install the filter assembly 150, the user inserts the end of the filter assembly 150 into the track groove 111 through the mounting opening 131 to install the filter assembly 150 on the middle frame 110. Overall, the filter assembly 150 can be removed and installed without opening the panel, making it more convenient to remove and install the filter assembly 150.

[0067] The air conditioner 100 also includes a base, a fan, and a heat exchanger. The base, middle frame 110, surface frame 130, fan, heat exchanger, and filter assembly 150 are the main components of the indoor unit of the air conditioner 100. The fan and heat exchanger are mounted on the base. The middle frame 110 is mounted on the base to enclose components such as the fan and heat exchanger. When the filter assembly 150 is mounted in the track groove 111, the filter assembly 150 is semi-enclosed and covers the outside of the heat exchanger. Air flowing into the air inlet of the middle frame 110 is filtered by the filter 170 before exchanging heat with the heat exchanger. The function of the filter assembly 150 is to filter dust in the air, thereby ensuring the cleanliness of the air supplied to the room.

[0068] It should be noted that in this embodiment, the face frame 130 and the middle frame 110 are formed separately. The face frame 130 is installed on the middle frame 110 by rotating, and the face frame 130 can be flipped upward to open. Since the face frame 130 does not need to be removed to remove the filter assembly 150, in some embodiments of the present application, the face frame 130 and the middle frame 110 can also be integrally formed as a single unit.

[0069] Generally, the indoor unit of the air conditioner 100 is provided with a plurality of filter assemblies 150. The middle frame 110 is provided with a plurality of groups of track grooves 111, and each group of track grooves 111 has two tracks arranged opposite to each other. The filter assemblies 150 are installed between the two guide rails in a one-to-one correspondence. The track is provided on the inner side of the middle frame 110, extending from the lower end of the front side of the middle frame 110 to the top of the middle frame 110, and then extending toward the rear side of the middle frame 110 through an arc transition. The side walls of the two opposite guide rails are provided with slide grooves 186, and the two sides of the width direction of the filter assembly 150 are clamped in the slide grooves 186. In this way, after the filter assembly 150 is installed, the filter assembly 150 can block the front side and top side of the middle frame 110.

[0070] In this embodiment, the track groove 111 has a downward-facing opening. This opening allows the end of the filter assembly 150 to be inserted into the track groove 111 during installation. Guided by the track groove 111, the filter assembly 150 then bends and fits within the track groove 111. The face frame 130 is a covering disposed outside the middle frame 110 to shield the middle frame 110 and the filter assembly 150, thereby enhancing the appearance of the indoor unit. The face frame 130 has a stepped surface 133 parallel to the top or bottom wall of the indoor unit. This stepped surface 133 aligns with the downward-facing opening at the bottom of the track groove 111, and the installation opening 131 is located on the stepped surface 133. The filter assembly 150 extends into the face frame 130 through the installation opening 131 and can be inserted into the track groove 111 through the opening.

[0071] This embodiment provides a stepped surface 133 on the face frame 130 and positions the mounting opening 131 on the stepped surface 133. This allows for better alignment of the mounting opening 131 with the opening of the track groove 111. When installing the filter assembly 150, the end of the filter assembly 150 is inserted into the face frame 130 through the mounting opening 131, allowing the top of the filter assembly 150 to be quickly inserted into the track groove 111. Furthermore, the stepped surface 133 prevents the mounting opening 131 from being visible from the front of the indoor unit, thereby enhancing the aesthetics of the indoor unit of the air conditioner 100.

[0072] Please refer to Figures 1 to 3 In this embodiment, the face frame 130 is provided with an air outlet 135, which is configured to supply air into the room. The air outlet 135 is located below the stepped surface 133. The stepped surface 133 of the face frame 130 transitions to the bottom plate via an arc surface, and the air outlet 135 is arranged on the arc. This allows the air outlet 135 to supply air downward at an angle. The installation opening 131 is connected to the air outlet 135. When the filter assembly 150 is removed, the air outlet 135 can avoid the filter assembly 150 so that the filter assembly 150 can be pulled out from the installation opening 131.

[0073] In this embodiment, the mounting opening 131 is connected to the air outlet 135, so that the position of the air outlet 135 can be used to avoid the filter assembly 150, making it easier for the user to pull the filter assembly 150 outward and insert the filter assembly 150 into the track groove 111. Secondly, connecting the mounting opening 131 to the air outlet 135 also facilitates the injection molding of the face frame 130.

[0074] Please refer to Figures 1 to 3 In this embodiment, a handle 151 is provided at the bottom end of the filter assembly 150 , and the handle 151 is exposed outside the installation opening 131 .

[0075] In this embodiment, a handle 151 is provided at the bottom end of the filter assembly 150 and the handle 151 is exposed. In this way, when the filter assembly 150 is removed, the user can easily pull the filter assembly 150 out through the handle 151.

[0076] Specifically, handle 151 is located in the middle of the width direction of the bottom end of filter assembly 150, and the front side of handle 151 is protruding. When filter assembly 150 is installed in track groove 111, the protruding portion of handle 151 abuts against stepped surface 133. The rest of filter assembly 150 and handle 151 are hidden inside by face frame 130.

[0077] Please refer to Figure 15In some other embodiments of the present application, the bottom wall of the filter assembly 150 is provided with a mounting groove 153, and a handle 155 is provided in the mounting groove 153. The handle 155 is rotatably mounted in the mounting groove 153. The handle 155 is specifically configured to have an extended state extending out of the mounting groove 153 and a retracted state retracted into the mounting groove 153. In the extended state, the handle 155 is exposed from the mounting opening 131.

[0078] This embodiment provides a mounting slot 153 on the bottom wall of the filter assembly 150, and a handle 155 is rotatably disposed within the mounting slot 153. To remove the filter assembly 150, the user first unfolds the handle 155 and then pulls the filter assembly 150 outward using the handle 155. After the filter assembly 150 is installed, the handle 155 can be rotated and retracted into the mounting slot 153. This allows the face frame 130 to shield the filter assembly 150 from view, enhancing the aesthetics of the air conditioner 100.

[0079] Please refer to Figures 4 to 14 In this embodiment, one of the filter assembly 150 and the middle frame 110 is provided with a snap-fit portion 117, and the other is provided with a snap-fit groove 181. When the filter assembly 150 is installed in the track groove 111, the snap-fit portion 117 is snap-fitted into the snap-fit groove 181.

[0080] Since the installation opening 131 is vertically downwardly arranged, this embodiment provides the clamping portion 117 and the clamping groove 181 , and the clamping portion 117 and the clamping groove 181 are engaged to prevent the filter assembly 150 from falling out of the installation opening 131 .

[0081] Please refer to Figure 4 In one embodiment, the filter assembly 150 is provided with engaging grooves 181 on both sides of the width direction near the bottom. The middle frame 110 is located at the bottom of the track groove 111, and is provided with engaging portions 117 on both sides of the track groove 111. When the filter assembly 150 is installed in the track groove 111, the engaging portions 117 engage with the engaging grooves 181.

[0082] In this embodiment, the filter assembly 150 is secured by providing snap-fit grooves 181 on both sides of the filter assembly 150 near the bottom widthwise direction, and snap-fit portions 117 are provided on both sides of the middle frame 110 at the bottom of the track groove 111. Furthermore, the snap-fit portions 117 on both sides of the track groove 111 can guide the ends of the filter assembly 150 during installation, making it easier to insert the filter assembly 150 into the track groove 111.

[0083] Specifically, the engaging groove 181 is an arc-shaped groove, and the engaging portion 117 is a cylinder. Thus, the provision of a cylinder allows the engaging grooves 181 of two adjacent filter screen assemblies 150 to engage with one engaging portion 117. The structure is simpler.

[0084] Please refer to Figures 1 to 14 In another installation method, the filter assembly 150 includes a filter frame 160, a filter 170, and a connecting arm 180. The connecting arm 180 is mounted on the filter frame 160. The connecting arm 180 can slide relative to the filter frame 160 between a first position and a second position. The top of the filter 170 is connected to the filter frame 160 near the top, and the bottom of the filter 170 is connected to the connecting arm 180. A snap-fit groove 181 is provided on the connecting arm 180, and the snap-fit portion 117 is provided on the middle frame 110. When the connecting arm 180 is in the first position, the connecting arm 180 is located at the bottom end of the filter frame 160 and pulls the filter 170 out so that the filter 170 is covered on one side of the filter frame 160. When the connecting arm 180 is in the second position, the connecting arm 180 is located at the top end of the filter frame 160 and pulls the bottom end of the filter assembly 150 upward, folding the filter assembly 150 in half.

[0085] Among them, when the filter assembly 150 is installed in the track groove 111 (that is, the filter assembly 150 is installed in the indoor unit), the connecting arm 180 is located in the first position, the clamping portion 117 is clamped in the clamping groove 181, and the filter frame 160 is clamped with the track groove 111, and the bottom end portion of the filter frame 160 is exposed at the installation opening 131. When installing the filter assembly 150 to the indoor unit, first move the connecting arm 180 to the first position (i.e., the bottom of the filter frame 160) so that the connecting arm 180 stretches the filter 170 and covers it on one side of the filter frame 160, then insert the mounting opening 131 at the top of the filter frame 160 inward into the track groove 111, and then push the filter frame 160 inward to extend the track groove 111 until the bottom end of the filter frame 160 and the connecting arm 180 also extend into the face frame 130 through the mounting opening 131, and the clamping portion 117 is clamped in the clamping groove 181, thereby completing the installation of the filter assembly 150. There is no need to disassemble the face frame 130 during the installation process.

[0086] When the user needs to remove the filter assembly 150, they pull the filter frame 160 outward. Since the connecting arm 180 is fixed to the middle frame 110 through the engagement portion 117 and the engagement groove 181, the filter frame 160 is partially pulled out of the installation opening 131 during the first stage of the outward pull. The connecting arm 180 moves from the first position to the second position relative to the filter frame 160. During this process, the bottom end of the filter 170 is pulled toward the top end of the filter frame 160 by the connecting arm 180, causing the filter 170 to fold in half. After the connecting arm 180 moves to the second position, the filter frame 160 is disengaged from the track groove 111 and the connecting arm 180 can no longer move relative to the filter frame 160. In the second stage, the filter frame 160 is pulled outward again, and the filter frame 160 drives the connecting arm 180 to move outward together, so that the engaging portion 117 is disengaged from the engaging groove 181 , and the connecting arm 180 is moved out of the installation opening 131 along with the filter frame 160 .

[0087] In this embodiment, the top of the filter 170 is connected to the top of the filter frame 160. A connecting arm 180 is movably mounted on the filter frame 160, and the bottom end of the filter assembly 150 is connected to the connecting arm 180. When the filter frame 160 slides to the first position at the bottom of the filter frame 160, the connecting arm 180 can pull the filter assembly 150 to unfold, so that the filter 170 is covered on one side of the filter frame 160, thereby filtering dust during use. Since dust on the filter assembly 150 is generally filtered by the filter 170 and adheres to the front of the filter 170, when the filter assembly 150 is pulled outward, the dust on the filter assembly 150 will rub against the side wall of the installation opening 131 and fall off, resulting in a poor user experience. In this embodiment, a connecting arm 180 is provided. When the filter assembly 150 is removed, since the clamping groove 181 is provided on the connecting arm 180, the user pulls the filter frame 160 outward when removing the filter assembly 150. Since the clamping portion 117 is clamped in the clamping groove 181, the connecting arm 180 does not move, and only the filter frame 160 moves outward. During the outward movement of the filter frame 160, the connecting arm 180 moves from the first position to the second position relative to the filter frame 160. During this process, the connecting arm 180 will pull the lower end of the filter 170 to fold the filter 170 up and down, and fold the windward side of the filter 170 inward, so that dust falling on the filter 170 will be caught in the folded part of the filter 170, thereby preventing dust on the filter 170 from falling when the filter assembly 150 is removed. Secondly, when cleaning the filter assembly 150, the connecting arm 180 drives the filter 170 to unfold and fold, thereby avoiding the mutual influence between the filter 170 and the filter frame 160, making the cleaning of the filter assembly 150 more convenient.

[0088] Please refer to Figures 1 to 14In this embodiment, filter screen 170 is disposed on the front (i.e., windward) side of filter screen assembly 150. The top of filter screen 170 is connected to the top of filter screen frame 160 by bonding or pressing. Connecting arm 180 is movably disposed on the front of filter screen frame 160, with a gap formed between connecting arm 180 and filter screen frame 160. When connecting arm 180 moves from a first position to a second position, the folded portion of filter screen 170 can extend through the gap between connecting arm 180 and filter screen frame 160.

[0089] It is worth noting that the two sides of the filter screen 170 in the width direction are not connected to the filter screen frame 160, so that the connecting arm 180 can fold the bottom of the filter screen 170 upward during movement to fold the windward side of the filter screen 170 inward.

[0090] Of course, in some embodiments of the present application, the filter assembly 150 may also be a conventional filter assembly 150 , that is, the filter 170 is fixedly arranged on the front or back of the filter assembly 150 .

[0091] In this embodiment, the connecting arm 180 includes a connecting portion 184 and sliding portions 185 connected to either side of the connecting portion 184. Slide grooves 186 are provided on the opposing sidewalls of the two sliding portions 185. The two sliding portions 185 are movably mounted on either side of the width of the filter frame 160 via the slide grooves 186. The connecting portion 184 is located on the side of the filter 170 away from the filter frame 160. A gap is formed between the connecting portion 184 and the filter frame 160. The bottom end of the filter assembly 150 extends into the gap and connects to the inner side of the connecting portion 184.

[0092] Specifically, when connecting arm 180 is mounted on filter frame 160, a gap is formed between the inner wall of connecting portion 184 and the outer wall of filter frame 160. The width of the gap is greater than twice the thickness of filter assembly 150. Therefore, when connecting arm 180 moves upward, the folded portion of filter 170 can extend downward from connecting arm 180 through the gap, while the unfolded portion of filter 170 abuts against the surface of filter frame 160 under the action of the sidewalls of the guide rail groove.

[0093] In this embodiment, the bottom portion of the filter 170 is folded toward the windward side of the filter 170 (i.e., bent toward the connection portion 184) to form a bent portion, and the leeward side of the bent portion is connected to the connection portion 184. When the connecting arm 180 moves from the first position to the second position, the connecting arm 180 drives the bottom end of the filter 170 toward the top of the filter frame 160. The folded portion of the filter 170 can extend downward through the connecting arm 180 with a gap between the connection portion 184 and the filter frame 160. In this embodiment, the bottom end of the filter 170 is folded toward the windward side of the filter 170 to form a bent portion, so that the bent portion is connected to the connection portion 184. In this way, after the filter 170 is folded, the windward side of the filter 170 will be folded inward, thereby preventing dust from falling.

[0094] Please refer to Figures 1 to 14 In this embodiment, the track groove 111 includes a first track groove section 113 and a second track groove section 115 connected in sequence. The first track groove section 113 is located near the mounting opening 131. The width of the first track groove section 113 (specified in the front-to-back direction of the indoor unit) gradually increases toward the mounting opening 131. The width of the second track groove section 115 (specified in the front-to-back direction of the indoor unit) corresponds to the thickness of the filter frame 160. The clamping portion 117 is located below the first track groove section 113. The clamping groove 181 is located on the back side of the sliding portion 185. When the filter assembly 150 is installed in the track groove 111, the top of the filter frame 160 is inserted into the second track groove section 115 by the first track groove section 113, and the connecting arm 180 is located below the first track groove section 113. The filter 170 is then attached to the filter frame 160 on both sides of its width due to the sidewalls (front sidewalls) of the second track groove section 115. The filter frame 160 is held in engagement with the sidewall of the second track groove section 115 by the support of the engaging portion 117. When the filter frame 160 is pulled outward and the connecting arm 180 moves to the second position relative to the filter frame 160, the top end of the filter frame 160 moves into the first track groove section 113. Due to the greater width of the first track groove 111, the filter frame 160 is released from engagement with the front sidewall of the track groove 111, thereby releasing the engagement between the filter frame 160 and the track groove 111. Subsequently, when the filter frame 160 is pulled outward again, the increased width of the first track groove 111 creates a clearance in front of the filter frame 160. When the sliding arm receives an outward pulling force, the sliding arm, guided by the engaging portion 117 and the engaging groove 181, can move forward, disengaging the engaging portion 117 from the engaging groove 181 and pulling the filter assembly 150 out of the mounting opening 131.

[0095] In this embodiment, the track groove 111 is set as the first track groove section 113 and the second track groove section 115, so that the width of the second track groove section 115 corresponds to the thickness of the filter frame 160. In this way, when the filter frame 160 is inserted into the second track groove section 115, the clamping portion 117 is clamped in the clamping groove 181 of the connecting arm 180, and a forward thrust is applied to the connecting arm 180 and the filter frame 160, so that the filter frame 160 is abutted against the front side wall of the second track groove section 115, thereby fixing the filter assembly 150. By gradually increasing the width of the first track groove section 113 toward the mounting opening 131, when the user pulls the end of the filter frame 160 outward to the first track groove section 113, the gradually increasing width of the first track groove section 113 provides space for the filter frame 160 and the connecting arm 180 to move forward, thereby facilitating the release of the engaging portion 117 from the engaging portion 117, allowing the filter frame 160 and the connecting arm 180 to be moved out of the mounting opening 131. By setting the width of the second track groove section 115 to match the thickness of the filter frame 160, when the filter assembly 150 is reinstalled in the track groove 111, the front sidewall of the second track groove section 115 exerts pressure on the filter 170, causing the widthwise sides of the filter 170 to conform to the widthwise sides of the filter frame 160.

[0096] It is worth noting that the main reason why the engaging portion 117 does not fall out of the engaging groove 181 during the first stage of pulling the filter frame 160 outward, but can fall out of the engaging groove 181 during the second stage of pulling the filter frame 160 outward, is that since the filter frame 160 is still partially inserted into the second track groove 111 during the first stage, the outer wall of the second track groove 111 exerts an inward thrust on the filter frame 160. This thrust offsets the forward component of the force exerted by the filter frame 160 during the pulling of the filter frame 160. Therefore, the engaging portion 117 does not fall out of the engaging groove 181 during the first stage of pulling the filter frame 160 outward. When the filter assembly 150 is installed, the clamping portion 117 exerts an outward thrust on the lower end of the filter frame 160, causing the filter frame 160 to move outward, causing the front face of the filter assembly 150 to abut against the front sidewall of the second track slot 115. Friction secures the filter assembly 150 to the second track slot 115. During the second stage of pulling the filter frame 160 outward, the filter frame 160 is completely removed from the second track slot 115. Since the first track slot 113 is wider than the second track slot 115, the clamping portion 117 prevents the front face of the filter assembly 150 from abutting against the front sidewall of the first track slot 113. Instead, a gap is formed between the two. The backward thrust applied to the filter frame 160 during this stage is muted, and only a small pulling force is required to release the clamping portion 117 from the clamping slot 181.

[0097] In this embodiment, each track groove 111 is provided with two engaging portions 117, which are located below the tracks on either side of the track groove 111. The back sides of the two sliding portions 185 are each provided with engaging grooves 181, which communicate with the chute 186. Once engaged with the engaging grooves 181, the engaging portions 117 extend into the chute 186 and abut against the back of the filter frame 160.

[0098] In this embodiment, the top of the filter frame 160 is provided with a first limiting boss 161 and a fixing structure 163, and the bottom of the filter frame 160 is provided with a second limiting boss 169. The connecting arm 180 is provided with a matching structure 182. When the connecting arm 180 is in the second position, the connecting arm 180 abuts the first limiting boss 161, and the fixing structure 163 cooperates with the matching structure 182 to maintain the connecting arm 180 in the second position. When the connecting arm 180 is in the first position, the connecting arm 180 abuts the second limiting boss 169, and the connecting arm 180 can move between the first limiting boss 161 and the second limiting boss 169.

[0099] In this embodiment, the first limiting boss 161 and the second limiting boss 169 are provided to limit the range of movement of the connecting arm 180 and prevent the connecting arm 180 from being dislodged from the ends of the filter frame 160. Furthermore, the fixing structure 163 and the matching structure 182 are provided to maintain the connecting arm 180 in the second position when the connecting arm 180 is in the second position, thereby preventing the connecting arm 180 from moving downward under the action of gravity when the filter assembly 150 is removed.

[0100] In one embodiment, the fixing structure 163 is a latching protrusion 165, and the mating structure 182 is a latching slot 183. The latching protrusion 165 is protruding near the top of the filter frame 160. The latching slot 183 is recessed in the sidewall of the chute 186. When the connecting arm 180 is in the second position, the latching protrusion 165 is engaged in the latching slot 183. When the connecting arm 180 is subjected to a downward external force, the latching protrusion 165 can be disengaged from the latching slot 183.

[0101] Generally, the locking protrusion 165 and the first limiting protrusion are arranged on the same side of the filter frame 160 , and the locking protrusion 165 is located below the first limiting boss 161 . The height of the locking protrusion 165 is smaller than the height of the first limiting boss 161 .

[0102] Please refer to Figures 1 to 14 In this embodiment, the locking protrusion 165 and the first limiting boss 161 are arranged on the same side of the filter assembly 150, thereby facilitating the manufacture of the filter frame 160. The height of the locking protrusion 165 is smaller than the height of the first limiting boss 161, which facilitates the removal of the locking protrusion 165 from the locking groove 183 under the action of an external force.

[0103] Specifically, there are two latching protrusions 165 and two first limiting bosses 161. The two latching protrusions 165 and the two first limiting bosses 161 are arranged on both sides of the filter assembly 150 in the width direction in a one-to-one correspondence. The latching protrusions 165 are located below the first limiting bosses 161 and are spaced apart from the first limiting bosses 161. When the connecting arm 180 is in the second position, the first limiting bosses 161 abut against the top wall of the connecting arm 180, and the connecting arm 180 will not pass over the first limiting bosses 161 under the action of external forces. The end of the latching protrusion 165 is provided with an arc surface or a guiding inclined surface. When the connecting arm 180 is subjected to an upward thrust, the latching protrusion 165 can be latched into the slot 183. When the connecting arm 180 is subjected to a downward external force, the latching protrusion 165 can be moved out of the slot 183.

[0104] Please refer to Figure 11 In another embodiment, the fixing structure 163 is a limiting groove 167. The limiting groove 167 is provided on the back of the filter frame 160, and two limiting grooves are provided on both sides in the width direction. The limiting groove 167 extends along the height direction of the filter frame 160, and the width of the limiting groove 167 gradually narrows from the bottom wall of the limiting groove 167 toward the top of the limiting groove 167. The matching structure 182 is a guide boss 187. The guide protrusion consists of two, and the two guide bosses 187 are provided on the side arms of the slide 186. The two guide bosses 187 are inserted into the two limiting grooves 167 in a one-to-one correspondence. When the connecting arm 180 moves between the first position and the second position, the guide boss 187 can slide relative to the limiting groove 167, and when the connecting arm 180 is in the second position, the guide boss 187 can be stuck between the two opposite side walls of the limiting groove 167.

[0105] In this embodiment, the fixing structure 163 is configured as a limiting groove 167, extending along the height of the filter frame 160. The width of the limiting groove 167 gradually narrows from the bottom wall of the limiting groove 167 toward the top of the limiting groove 167. The mating structure 182 is configured as a guide boss 187, which extends into the limiting groove 167. Thus, the limiting groove 167 and the guide boss 187 cooperate to guide the connecting arm 180 during movement. When the connecting arm 180 moves to the second position, the narrow sidewalls of the limiting groove 167 clamp the guide boss 187, thereby preventing the connecting arm 180 from moving downward under the action of gravity.

[0106] It should be noted that the width of the limiting groove 167 corresponding to the second position is narrower, and it can achieve an interference fit with the guide boss 187, thereby overcoming the gravity of the connecting arm 180 and maintaining the connecting arm 180 in the second position.

[0107] Please refer to Figures 1 to 14In this embodiment, second limiting boss 169 is positioned on the front side of the lower frame of filter screen frame 160. Second limiting boss 169 is provided with a V-shaped guide groove, and the lower bottom wall of connecting portion 184 is also V-shaped. Thus, when connecting arm 180 moves to the first position, the V-shaped guide groove cooperates with the lower bottom wall of connecting portion 184 to guide the filter screen frame 160 in the width direction. This allows filter screen 170 to be flattened when connecting arm 180 moves to the first position.

[0108] In summary, the air conditioner 100 provided in this embodiment provides a mounting opening 131 at a position on the face frame 130 corresponding to the track groove 111 of the middle frame 110, and allows the filter assembly 150 to be installed within the track groove 111 of the middle frame 110, with a portion exposed outside the mounting opening 131. Thus, when removing the filter assembly 150, the user can simply pull the filter assembly 150 from the position exposed by the mounting opening 131, and pull the filter assembly 150 out of the track groove 111 to remove the filter assembly 150. When installing the filter assembly 150, the user can insert the end of the filter assembly 150 into the track groove 111 through the mounting opening 131 to install the filter assembly 150 on the middle frame 110. Overall, the filter assembly 150 can be removed and installed without opening the panel, making it more convenient to remove and install the filter assembly 150.

[0109] Although the present invention is disclosed as above, it is not limited thereto. Any person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope defined by the claims.
