DETAILED DESCRIPTION

[0047] 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.

[0048] Please refer to Figure 1 This embodiment provides an air conditioner 300, which includes an indoor unit and a filter assembly 100. The indoor unit is provided with an air inlet. A guide rail groove 310 is provided in the indoor unit corresponding to the air inlet. The filter assembly 100 is detachably mounted in the guide rail groove 310 and is covered by the air inlet.

[0049] Typically, an indoor unit includes a base, a middle frame, and a panel. The middle frame is mounted to the base. The panel is mounted to the middle frame. The air inlet is located at the top of the middle frame. Guide rail slots 310 are provided in the middle frame, typically in pairs. The filter assembly 100 is installed between a pair of guide rail slots 310. The two sides of the width of the filter assembly 100 snap into place within the two guide rail slots 310. To clean the filter assembly 100, pull it out of the guide rail slots 310 and remove it from the middle frame.

[0050] Please refer to Figures 2 to 8 In this embodiment, the filter assembly 100 has a windward side 111 and a leeward side 113. When the filter assembly 100 is installed in the indoor unit, indoor air flows from the windward side 111 to the leeward side 113. The filter assembly 100 includes a filter frame 110 and a filter 140. The filter 140 is disposed on the windward side 111 of the filter frame 110.

[0051] In this embodiment, the filter 140 is arranged on the windward side 111 of the filter frame 110, so that the filter frame 110 supports the filter 140 on the back side of the filter 140, and the windward side of the filter 140 is affected by the filter frame 110, thereby facilitating the cleaning of the filter 140.

[0052] Furthermore, the filter frame 110 includes a frame 115 and a plurality of support ribs 117, which are disposed within and connected to the frame 115. The surfaces of all the support ribs 117 on the windward side 111 are coplanar with the surface of the frame 115 on the windward side 111.

[0053] In this embodiment, the surface of all the support ribs 117 on the windward side 111 is coplanar with the surface of the frame 115 on the windward side 111, so that the surface of the windward side 111 of the filter frame 110 is flat. After the filter 140 is installed on the filter frame 110, the filter 140 is flat, which makes it easier to clean the filter 140.

[0054] The frame 115 is generally rectangular and includes four frames: top, bottom, left, and right. Multiple support ribs 117 are arranged horizontally within the rectangular frame, with their ends connected to the left and right frames. Another portion of support ribs 117 is vertically spaced within the frame 115, with their ends connected to the top and bottom frames. The frames and support ribs 117 are typically integrally formed using injection molding. When the filter is unfolded, the support ribs 117 support the filter 140 from the back.

[0055] In this embodiment, a reinforcing rib 119 is provided on the side of the filter frame 110 located on the leeward side 113. By providing the reinforcing rib 119 on the side of the filter frame 110 located on the leeward side 113, the strength of the filter frame 110 can be enhanced.

[0056] In one embodiment of the present application, the filter screen 140 is fixed to the frame by bonding. Of course, the filter screen 140 can also be fixed to the four frames of the frame by pressing.

[0057] Please refer to Figures 2 to 8 In this embodiment, the filter assembly 100 further includes a sliding arm 150. The top end of the filter 140 is connected to the top of the filter frame 110 on the windward side 111. The sliding arm 150 is mounted on the filter frame 110, and the bottom end of the filter 140 is connected to the sliding arm 150. The sliding arm 150 is capable of sliding relative to the filter frame 110. When the sliding arm 150 slides to a first position, the sliding arm 150 is located at the bottom end of the filter frame 110. The sliding arm 150 can pull the filter 140 out and cover the windward side 111 of the filter frame 110. When the sliding arm 150 slides to a second position, the sliding arm 150 is located at the top end of the filter frame 110. The sliding arm 150 folds the bottom end of the filter 140 toward the top of the filter frame 110, exposing the windward side 111 of the filter frame 110.

[0058] Because the filter screen 140 blocks the windward side of the filter frame 110, the windward side of the filter frame 110 cannot be cleaned properly. The present application connects the top of the filter screen 140 to the top of the filter frame 110 on the windward side 111. The sliding arm 150 is movably mounted on the filter frame 110, and the bottom end of the filter screen 140 is connected to the sliding arm 150. When the filter frame 110 slides to the first position at the bottom of the filter frame 110, the sliding arm 150 can pull the filter screen 140 out to cover the windward side 111 of the filter frame 110. When the sliding arm 150 slides to the second position at the top of the filter frame 110, the sliding arm 150 folds the bottom end of the filter screen 140 toward the top of the filter frame 110, exposing the windward side 111 of the filter frame 110, thereby conveniently cleaning the windward side of the filter frame 110.

[0059] Specifically, the top of the filter screen 140 can be fixed to the upper frame of the frame 115 by bonding. The lower end of the filter screen 140 is connected to the sliding arm 150 by bonding. The two sides of the filter screen 140 in the width direction are not connected to the filter screen frame 110. When the filter screen 140 is in normal use, the sliding arm 150 is located in the first position, and the filter screen 140 is flattened and stretched on the windward side of the filter screen frame 110 at the bottom end of the filter screen frame 110. When cleaning, the sliding arm 150 can be pushed upward to the second position to fold the filter screen 140 in half. The folded filter screen 140 can be folded upward again to expose the windward side of the filter screen frame 110, so that the windward side of the filter screen frame 110 and the leeward side of the filter screen 140 can be cleaned. The existing filter 140 is directly fixed on the leeward side of the filter frame 110. Due to the obstruction of the filter 140, the leeward side of the filter frame 110 cannot be cleaned. The windward side of the filter 140 is also partially obstructed by the filter frame 110, resulting in a dead corner that cannot be cleaned. However, this embodiment installs the filter 140 in the above manner, which can better achieve the cleaning of the filter 140 and the filter frame 110 and avoid mutual obstruction between the two.

[0060] Please refer to Figures 2 to 8 In this embodiment, the bottom end of the filter screen is folded in half from the windward side of the filter screen 140 toward the top of the filter screen 140 to form a bent portion 141. The bent portion 141 is connected to the sliding arm 150. When the sliding arm 150 moves from the first position to the second position, the sliding arm 150 can drive the bottom end of the filter screen 140 to move toward the top of the filter screen frame 110, thereby folding the filter screen 140 in half, exposing the leeward side of the filter screen 140 and folding the windward side of the filter screen 140 inward.

[0061] In this embodiment, the bottom end of the filter 140 is bent toward the top to form a bent portion 141, so that the outer side of the leeward side corresponding to the bent portion 141 is bent and connected to the sliding arm 150. The purpose of this arrangement is to facilitate the folding of the filter 140 along the side of the windward side when the sliding arm 150 slides toward the second position, and the leeward side of the filter 140 is exposed. This makes it easier for users to clean the leeward side of the filter 140, and the windward side of the filter 140 is folded inward.

[0062] The bending portion 141 formed by the bottom end of the filter 140 being bent toward the top can be understood as a section of the lower side of the filter 140 being folded upward toward the windward side of the filter 140, thereby forming a predetermined folded direction for the filter 140. As the sliding arm 150 moves upward, it pulls the folded portion forward, thereby folding the windward side 111 of the filter 140 inward, exposing the leeward side 113 of the filter 140, and facilitating cleaning of the leeward side 113 of the filter 140.

[0063] In addition, when the filter 140 is removed from the indoor unit, the sliding arm 150 moves toward the second position relative to the filter frame 110 as the filter 140 is pulled out of the guide rail groove 310. In this way, after the filter assembly 100 is removed, the filter 140 is also folded in half. After folding, the windward side of the filter 140 is folded inward, which can catch the dust on the filter 140, thereby preventing the dust on the filter 140 from falling when the filter 140 is removed.

[0064] Specifically, a snap-fit portion can be provided on the middle frame. After the filter assembly 100 is installed in the indoor unit, the snap-fit portion engages with the sliding arm 150. When removing the filter 140, the sliding arm 150 remains stationary relative to the middle frame as the filter frame 110 is pulled out of the guide rail groove 310. Only the filter frame 110, carrying the filter 140, moves outward. During this process, the filter 140 folds in half as the filter frame 110 moves outward until the filter frame 110 is free from the guide rail groove 310, at which point the snap-fit releases its engagement with the sliding arm 150. This allows the filter 140 to be folded in half with the windward side of the filter 140 folded inward when the filter assembly 100 is removed. This prevents dust from falling from the windward side of the filter 140 when the filter assembly 100 is removed.

[0065] In this embodiment, the sliding arm 150 includes a connecting portion 151 and sliding portions 153 connected to either side of the connecting portion 151. Slide grooves 155 are provided on the opposing sidewalls of the two sliding portions 153. Both sliding portions 153 are movably mounted on either side of the filter frame 110 in the width direction via the slide grooves 155. The connecting portion 151 is located on the windward side 111 of the filter 140 and is connected to the bent portion 141 of the filter 140.

[0066] Specifically, when the sliding arm 150 is mounted on the filter frame 110, a gap is formed between the inner wall of the connecting portion 151 and the outer wall of the filter frame 110. The width of the gap is greater than twice the thickness of the filter 140. Therefore, when the sliding arm 150 moves upward, the folded portion of the filter 140 can extend from below the sliding arm 150, while the unfolded portion of the filter 140 abuts against the windward surface of the filter frame 110 under the action of the sidewalls of the guide rail groove 310.

[0067] In this embodiment, a first position-limiting boss 121 is provided on the top of the filter frame 110. When the sliding arm 150 is in the second position, the sliding arm 150 abuts against the first position-limiting boss 121.

[0068] In this embodiment, the first limiting boss 121 is provided to limit the movement range of the sliding arm 150 , thereby preventing the sliding arm 150 from falling out of the top end of the filter frame 110 .

[0069] The first limiting bosses 121 are provided on both sides of the width direction of the filter frame 110. When the filter 140 moves to the second position, the sliding parts 153 on both sides abut against the two first limiting bosses 121 respectively.

[0070] Of course, in other embodiments of the present application, the first limiting protrusion may be disposed on the windward side of the upper frame of the filter frame 110. Alternatively, the first limiting boss 121 may be disposed on the sliding arm 150, and a snap-fitting groove may be disposed at the upper end of the filter frame 110. When the filter 140 moves to the second position, the first limiting boss 121 snaps into the snap-fitting groove.

[0071] Please refer to Figures 2 to 8 In this embodiment, a second limiting boss 123 is provided at the bottom end of the filter frame 110. When the sliding arm 150 is in the first position, the sliding arm 150 abuts against the second limiting boss 123. The second limiting boss 123 can limit the sliding arm 150 and prevent the filter 140 from being pulled and damaged.

[0072] Furthermore, a second limiting boss 123 is provided along the length of the sliding arm 150. A guide groove 125 is recessed downwardly at the top of the second limiting boss 123. The guide groove 125 comprises a first guide surface 127 and a second guide surface 129, which are inclined in opposite directions. A guide boss 157 is provided at the bottom end of the sliding arm 150, corresponding to the guide groove. When the sliding arm 150 moves from the second position to the first position, the first and second guide surfaces 127, 129 cooperate with the guide boss 157 to guide the sliding arm 150.

[0073] In this embodiment, a guide boss 157 is provided on the sliding arm 150, and a guide groove 125 is provided on the second limiting boss 123. In this way, when the sliding arm 150 moves downward, the sliding arm 150 can be guided in the width direction of the filter frame 110, so that the sliding arm 150 can stretch and flatten the filter 140.

[0074] Furthermore, the guide groove 125 is a V-shaped groove, and the guide boss 157 matches the shape of the guide groove 125. When the sliding arm 150 moves downward, the guide groove 125 and the guide boss 157 can guide in the width direction, so that the pull-down rod is located at a preset position when in the second position, thereby stretching and flattening the filter screen 140.

[0075] In this embodiment, the left and right side frames of the filter frame 110 are provided with limiting slots 131 along their length, with the width of the limiting slots 131 narrowing toward the top of the filter frame 110. The rear sidewalls of the slide slots 155 on both sides of the sliding arm 150 are each provided with a protrusion 159. The two protrusions 159 are inserted into the two limiting slots 131 in a one-to-one correspondence.

[0076] Please refer to Figures 1 to 8 In this embodiment, by providing a retaining groove 131 on the back of the filter frame 110 and a protruding block 159 on the sliding arm 150, both ends of the sliding arm 150 can move synchronously. The width of the retaining groove 131 is narrowed toward the top of the filter frame 110. Thus, when the sliding arm 150 moves to the second position, the protruding block 159 engages with the side wall of the retaining groove 131, preventing the sliding arm 150 from falling.

[0077] Of course, in some embodiments of the present application, a buckle is further provided on the top of the filter frame 110, and a slot is provided on the sliding arm 150. When the sliding arm 150 moves up to the second position, the buckle can be engaged in the slot, thereby preventing the sliding arm 150 from moving down under the action of gravity.

[0078] It should also be noted that when the filter assembly 100 is installed between the guide rail grooves 310 of the middle frame, the outer walls of the guide rail grooves 310 on both sides will apply pressure to the two sides of the width direction of the filter 140, so that the two sides of the width direction of the filter 140 are attached to the left and right sides of the frame of the filter frame 110, thereby avoiding the direct formation of a gap between the filter 140 and the frame of the filter frame 110.

[0079] In summary, the filter assembly 100 and the air conditioner 300 provided in this embodiment are configured such that the filter 140 is arranged on the windward side 111 of the filter frame 110, so that the filter frame 110 supports the filter 140 on the back side of the filter 140, and the windward side of the filter 140 is affected by the filter frame 110, thereby facilitating the cleaning of the filter 140.

[0080] 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.
