[0010] When the connecting arm slides to the second position, the connecting arm is located at the top end of the filter screen framework, and the connecting arm pulls the bottom end of the filter screen upward so that the filter screen is folded in half.

[0011] In the present application, the top end of the filter screen is connected to the top of the filter screen framework. The connecting arm is movably mounted on the filter screen framework, and the bottom end of the filter screen is connected to the connecting arm. When the filter screen framework slides to the first position at the bottom end of the filter screen framework, the connecting arm can pull the filter screen to unfold so that the filter screen is arranged at one side of the filter screen framework, thereby filtering dust during use. When the connecting arm slides to the second position at the top of the filter screen framework during cleaning of the filter screen, the connecting arm folds the bottom end of the filter screen toward the top of the filter screen framework, thereby exposing the side of the filter screen framework on which the filter screen is arranged and the side of the filter screen framework which is attached to the filter screen. This can avoid mutual blocking of the filter screen and the filter screen framework during cleaning, thereby facilitating the cleaning of the filter screen subassembly.

[0012] In an optional embodiment, the top of the filter screen framework is provided with a first limiting boss;

[0013] When the connecting arm is in the second position, the connecting arm abuts against the first limiting boss.

[0014] The present application can limit the movement range of the connecting arm by providing the first limiting boss, so as to avoid the connecting arm from being pulled out of the top end of the filter screen framework when the connecting arm is sliding towards the top of the filter screen framework.

[0015] In an optional embodiment, the filter screen framework is provided with a fixing structure, and the connecting arm is provided with a cooperating structure;

[0018] In an optional embodiment, the fixing structure is a clamping protrusion, and the cooperating structure is a clamping groove, which is recessed in the connecting arm. When the connecting arm is in the second position, the clamping protrusion is clamped in the clamping groove, and when the connecting arm is subjected to an external force in the direction of the first position, the clamping protrusion can move out of the clamping groove.

[0019] The present application sets the fixing structure as a clamping protrusion and sets the cooperating structure as a clamping groove, so that the clamping protrusion clamped in the clamping groove can conveniently fix the connecting arm in the second position.

[0020] In an optional embodiment, the clamping protrusion and the first limiting boss are arranged on the same side of the filter screen framework, and the clamping protrusion is located below the first limiting boss, and the protruding height of the clamping protrusion is less than the protruding height of the first limiting boss.

[0021] The present application arranges the clamping protrusion and the first limiting boss on the same side of the filter screen framework, which facilitates the manufacturing of the filter screen framework. Moreover, the protruding height of the clamping protrusion is less than the protruding height of the first limiting boss, which facilitates the clamping protrusion to move out of the clamping groove under the action of an external force.

[0022] In an optional embodiment, the fixing structure is a limiting groove, the limiting groove extends along the height direction of the filter screen framework, and the width of the limiting groove gradually narrows from the bottom wall of the limiting groove to the top of the limiting groove;

[0023] The cooperating structure is a guide protrusion, which is arranged on the side of the connecting arm close to the filter screen framework and is inserted into the limiting groove;

[0024] The guide boss is slidable relative to the limiting groove when the connecting arm moves between the first position and the second position, and the guide boss is clamped between the opposite two side walls of the limiting groove when the connecting arm is in the second position.

[0025] The fixed structure is the limiting groove, which extends along the height direction of the filter screen framework, and the width of the limiting groove gradually narrows from the bottom wall to the top of the limiting groove. The cooperating structure is the guide boss, which extends into the limiting groove, so that the limiting groove and the guide boss can guide the connecting arm during movement. When the connecting arm moves to the second position, the guide boss is clamped between the opposite two side walls of the limiting groove due to the narrow width of the limiting groove, thereby avoiding the connecting arm from moving downward under the action of gravity.

[0026] In an optional embodiment, the connecting arm includes a connecting portion and two sliding portions connected to the two sides of the connecting portion;

[0027] The opposite two side walls of each sliding portion are provided with a sliding groove, and each sliding portion is movably installed on the two sides of the filter screen framework in the width direction through the sliding groove;

DETAILED DESCRIPTION

[0049] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the drawings.

[0050] Please refer to Figure 1 The embodiment provides an air conditioner 300, which comprises an indoor unit and a filter assembly 100, and the indoor unit is provided with an air inlet. A guide rail groove 310 is arranged in the indoor unit corresponding to the air inlet, and the filter assembly 100 is detachably mounted in the guide rail groove 310 and covers the air inlet.

[0051] Generally, the indoor unit comprises a base, a middle frame and a panel. The middle frame is mounted on the base. The panel is mounted on the middle frame. The air inlet is arranged at the top of the middle frame. The guide rail groove 310 is arranged in the middle frame, and the guide rail groove 310 is generally arranged in pairs. The filter assembly 100 is mounted between a group of guide rail grooves 310. When the filter assembly 100 needs to be cleaned, the filter assembly can be pulled out of the guide rail groove 310 to be detached from the middle frame.

[0052] Please refer to Figures 1 to 8 In the embodiment, the filter assembly 100 comprises a filter frame 110, a filter screen 130 and a connecting arm 150. The connecting arm 150 is mounted on the filter frame 110, and the connecting arm 150 can slide relative to the filter frame 110. The top end of the filter screen 130 is connected to the position close to the top end of the filter frame 110, and the bottom end of the filter screen 130 is connected to the connecting arm 150. When the connecting arm 150 slides to a first position, the connecting arm 150 is located at the lower end of the filter frame 110, and the connecting arm 150 pulls and unfolds the filter screen 130 to cover one side of the filter frame 110. When the connecting arm 150 slides to a second position, the connecting arm 150 is located at the top end of the filter frame 110, and the connecting arm 150 pulls up the bottom end of the filter screen 130 to fold the filter screen 130.

[0053] The filter screen 130 is generally adhered to one side of the filter screen framework 110 in the prior art, so that the filter screen 130 and the filter screen framework 110 will block each other, resulting in inconvenience in cleaning the filter screen assembly 100. In the present embodiment, the top end of the filter screen 130 is connected to the top of the filter screen framework 110. The connecting arm 150 is movably installed on the filter screen framework 110, and the bottom end of the filter screen 130 is connected to the connecting arm 150. When the filter screen framework 110 slides to the first position at the bottom end of the filter screen framework 110, the connecting arm 150 can pull and unfold the filter screen 130, so that the filter screen 130 is arranged on one side of the filter screen framework 110, thereby filtering dust during use. When the connecting arm 150 slides to the second position at the top of the filter screen framework 110 during cleaning of the filter screen 130, the connecting arm 150 folds the bottom end of the filter screen 130 towards the top of the filter screen framework 110, so that the side of the filter screen framework 110 on which the filter screen 130 is arranged is exposed, and the side of the filter screen 130 which is attached to the filter screen framework 110 is exposed. Thus, the filter screen 130 and the filter screen framework 110 do not block each other during cleaning, thereby making the cleaning of the filter screen assembly 100 more convenient.

[0054] Please refer to Figure 2 In the present embodiment, the middle frame is provided with a buckle 330, and the connecting arm 150 is provided with a buckle groove 151. When the filter screen assembly 100 is installed in the indoor unit, the connecting arm 150 is located at the first position, and the buckle 330 is buckled in the buckle groove 151. When the filter screen assembly 100 needs to be removed, the filter screen framework 110 is pulled outward. At this time, since the buckle 330 is buckled in the buckle groove 151, only the filter screen framework 110 moves with the filter screen 130, and the connecting arm 150 is relatively stationary with respect to the filter screen 130. Thus, during the removal process, the connecting arm 150 will move from the first position to the second position with respect to the filter screen framework 110, so as to pull up the bottom end of the filter screen 130 and fold the filter screen 130 in half. Thus, during the removal of the filter screen assembly 100, the dust falling from the filter screen 130 will fall into the folded area of the filter screen 130 and be caught by the filter screen 130. After the connecting arm 150 moves to the second position with respect to the filter screen framework 110, the filter screen framework 110 is pulled again. At this time, the connecting arm 150 will not move with respect to the filter screen framework 110. The external force for pulling the filter screen framework 110 will move the connecting arm 150 together, so that the buckle 330 is pulled out of the buckle groove 151, thereby completing the removal of the filter screen assembly 100. Thus, during the removal of the filter screen assembly 100, the connecting arm 150 does not need to be moved to the second position separately, making the operation more convenient.

[0055] In the present embodiment, the filter screen 130 is arranged on the front side of the filter screen framework 110, i.e. the side facing the wind. When the connecting arm 150 is at the first position, the filter screen 130 is pulled and unfolded to be flat on the front side of the filter screen 130. Of course, in some other embodiments of the present application, the filter screen 130 can also be arranged on the back side of the filter screen framework 110.

[0056] Specifically, the top of the filter screen 130 can be fixed to the upper frame of the filter screen frame by means of adhesion. The lower end of the filter screen 130 is connected to the connecting arm 150 by means of adhesion. The two sides of the filter screen 130 in the width direction are not connected to the filter screen frame 110. When the filter screen 130 is in normal use, the connecting arm 150 is located at the first position at the bottom end of the filter screen frame 110, and the connecting arm 150 can pull the filter screen 130 to be laid flat on one side of the filter screen frame 110. When cleaning, the connecting arm 150 can be pushed upward to the second position, so that the filter screen 130 is folded in half. When the folded filter screen 130 is further folded upward, the windward surface of the filter screen frame 110 is exposed, so that the filter screen frame 110 and the filter screen 130 can be cleaned. Then, the connecting arm 150 is pulled to the first position, so that the filter screen 130 is laid flat to clean the other side of the filter screen 130, thereby avoiding mutual shielding between the filter screen 130 and the filter screen frame 110.

[0057] In the embodiment, the connecting arm 150 includes a connecting portion 159 and sliding portions 161 connected to the two sides of the connecting portion 159. The two sliding portions 161 are provided with sliding grooves 163 on the opposite side walls, and the two sliding portions 161 are movably installed on the two sides of the filter screen frame 110 in the width direction through the sliding grooves 163. The connecting portion 159 is located on the side of the filter screen 130 away from the filter screen frame 110. A gap is formed between the connecting portion 159 and the filter screen frame 110, and the bottom end of the filter screen 130 extends into the gap and is connected to the side surface of the connecting portion 159.

[0058] Specifically, when the connecting arm 150 is installed on the filter screen frame 110, a gap is formed between the inner wall surface of the connecting portion 159 and the outer wall surface of the filter screen frame 110, and the width of the gap is greater than twice the thickness of the filter screen 130. In this way, when the connecting arm 150 moves upward, the folded part of the filter screen 130 can extend out from below the connecting arm 150, and the part of the filter screen 130 that is not folded can abut against the surface of the filter screen frame 110 under the action of the side wall of the guide groove 310.

[0059] In the embodiment, the bottom end of the filter screen 130 is folded toward the side of the windward side of the filter screen 130, so that the side of the leeward side of the bottom end of the filter screen 130 is connected to the connecting portion 159. When the connecting arm 150 moves from the first position to the second position, the connecting arm 150 drives the bottom end of the filter screen 130 to move toward the top of the filter screen frame 110, and the folded part of the filter screen 130 can extend downward from the connecting arm 150 through the gap between the connecting portion 159 and the filter screen frame 110. In the embodiment, the bottom end of the filter screen 130 is folded toward the side of the windward side of the filter screen 130 and then connected to the connecting portion 159. In this way, after the filter screen 130 is folded, the side of the windward surface of the filter screen 130 is folded inward, thereby avoiding the problem of dust falling.

[0060] In the embodiment, the top of the filter screen framework 110 is provided with a first limiting boss 111. When the connecting arm 150 is in the second position, the connecting arm 150 abuts against the first limiting boss 111.

[0061] When the filter screen assembly 100 is disassembled, the filter screen framework 110 is pulled to be disassembled. If the pulling force is too large, the connecting arm 150 will be pulled out of the top end of the filter screen framework 110. The embodiment is provided with the first limiting boss 111. When the connecting arm 150 moves to the first position, the connecting arm 150 can abut against the first limiting boss 111, so as to limit the movement range of the connecting arm 150 and avoid the connecting arm 150 from being pulled out of the top end of the filter screen framework 110.

[0062] The first limiting boss 111 is provided with two first limiting bosses 111, which are respectively arranged on the two sides in the width direction of the filter screen framework 110. When the filter screen 130 moves to the second position, the sliding parts 161 on the two sides of the connecting arm 150 respectively abut against the two first limiting bosses 111.

[0063] Of course, in some other embodiments of the application, the first limiting boss 111 can be arranged on the front or back of the top of the filter screen framework 110. The first limiting boss 111 can also be arranged on the connecting arm 150, and the clamping groove 155 is arranged on the upper end of the filter screen framework 110. When the filter screen 130 moves to the second position, the first limiting boss 111 is clamped in the clamping groove 155.

[0064] When the connecting arm 150 is in the second position, the connecting arm 150 will slide downward under the action of gravity. That is, after the buckle 330 on the middle frame is disengaged from the clamping groove, the connecting arm 150 will slide downward under the action of gravity, so that the dust collected at the folded part of the filter screen 130 will fall off, which will affect the user experience.

[0065] Please refer to Figures 3 to 8 In the embodiment, the filter screen framework 110 is provided with a fixing structure 113, and the connecting arm 150 is provided with a cooperating structure 153. When the connecting arm 150 is in the second position, the fixing structure 113 cooperates with the cooperating structure 153 to keep the connecting arm 150 in the second position.

[0066] The embodiment is provided with the fixing structure 113 on the filter screen framework 110 and the cooperating structure 153 on the connecting arm 150. When the connecting arm 150 is in the second position, the fixing structure 113 cooperates with the cooperating structure 153 to keep the connecting arm 150 in the second position and avoid the connecting arm 150 from moving downward.

[0067] Please refer to Figures 3 to 6In one embodiment, the fixing structure 113 is a clamping protrusion 115, and the cooperating structure 153 is a clamping slot 155. The clamping protrusion 115 is protruded on the filter screen framework 110 near the top. The clamping slot 155 is recessed on the sidewall of the sliding slot 163. When the connecting arm 150 is in the second position, the clamping protrusion 115 is clamped in the clamping slot 155, and when the connecting arm 150 is subjected to an external force in the direction of the first position, the clamping protrusion 115 can be moved out of the clamping slot 155.

[0068] In this embodiment, the fixing structure 113 is set as the clamping protrusion 115, and the cooperating structure 153 is set as the clamping slot 155, so that the clamping protrusion 115 clamped in the clamping slot 155 can conveniently fix the connecting arm 150 in the second position.

[0069] Specifically, the clamping protrusion 115 and the first limiting protrusion are arranged on the same side of the filter screen framework 110, and the clamping protrusion 115 is below the first limiting protrusion 111. The protruding height of the clamping protrusion 115 is less than the protruding height of the first limiting protrusion 111.

[0070] In this embodiment, the clamping protrusion 115, the first limiting protrusion 111, and the clamping protrusion 115 are arranged on the same side of the filter screen framework 110, which facilitates the manufacture of the filter screen framework 110. And the protruding height of the clamping protrusion 115 is less than the protruding height of the first limiting protrusion 111, which facilitates the movement of the clamping protrusion 115 out of the clamping slot 155 under the action of an external force.

[0071] Please refer to Figures 3 to 6 Specifically, the clamping protrusion 115 has two, the first limiting protrusion 111 has two, and the two clamping protrusions 115 and the two first limiting protrusions 111 are arranged on the two sides of the filter screen assembly 100 in the width direction one by one. And the clamping protrusion 115 is below the first limiting protrusion 111 and is arranged in a spaced manner. When the connecting arm 150 is in the second position, the first limiting protrusion 111 abuts against the top wall of the connecting arm 150, and the connecting arm 150 will not pass over the first limiting protrusion 111 under the action of an external force. And the end of the clamping protrusion 115 is provided with an arc surface or a guide slope. When the connecting arm 150 is subjected to an upward pushing force, the clamping protrusion 115 can be clamped into the clamping slot 155, and when the connecting arm 150 is subjected to a downward external force, the clamping protrusion 115 can be moved out of the clamping slot 155.

[0072] Please refer to Figure 7 and Figure 8In another embodiment, the fixing structure 113 is a limiting groove 117. The limiting groove 117 is arranged on the back of the filter screen framework 110, and two limiting grooves 117 are arranged on both sides in the width direction. The limiting groove 117 extends along the height direction of the filter screen framework 110, and the width of the limiting groove 117 gradually narrows from the bottom wall of the limiting groove 117 to the top of the limiting groove 117. The matching structure 153 is a guide boss 167. Two guide bosses 167 are arranged on the side arms of the sliding groove 163. The two guide bosses 167 are inserted into the two limiting grooves 117 one by one. When the connecting arm 150 moves between the first position and the second position, the guide boss 167 can slide relative to the limiting groove 117, and when the connecting arm 150 is in the second position, the guide boss 167 can be clamped between the two opposite side walls of the limiting groove 117.

[0073] In this embodiment, the fixing structure 113 is a limiting groove 117, and the limiting groove 117 extends along the height direction of the filter screen framework 110, and the width of the limiting groove 117 gradually narrows from the bottom wall of the limiting groove 117 to the top of the limiting groove 117. The matching structure 153 is a guide boss 167, and the guide boss 167 extends into the limiting groove 117. In this way, the limiting groove 117 and the guide boss 167 can guide the connecting arm 150 during movement. When the connecting arm 150 moves to the second position, the guide boss 167 can be clamped by the two opposite side walls of the limiting groove 117 due to the narrow width of the limiting groove 117, thereby avoiding the connecting arm 150 from moving downward under the action of gravity.

[0074] It should be noted that the limiting groove has a narrow width corresponding to the second position, which can achieve interference fit with the guide boss 167, thereby overcoming the weight of the connecting arm 150 and maintaining the connecting arm 150 in the second position.

[0075] Please refer to Figures 2 to 8 In this embodiment, the bottom end of the filter screen framework 110 is provided with a second limiting boss 119. When the connecting arm 150 is in the first position, the connecting arm 150 abuts against the second limiting boss 119. By arranging the second limiting boss 119, the connecting arm 150 can be limited, thereby avoiding damage to the filter screen 130.

[0076] It should be further noted that when the filter screen assembly 100 is installed between the guide rail grooves 310 of the middle frame, the outer side walls of the two guide rail grooves 310 can apply pressure to both sides of the filter screen 130 in the width direction, so that both sides of the filter screen 130 in the width direction are attached to the frames on both sides of the filter screen framework 110, thereby avoiding gaps between the filter screen 130 and the frames of the filter screen framework 110.

[0077] In conclusion, the filter screen assembly 100 and the air conditioner 300 provided by the embodiment are characterized in that the top end of the filter screen 130 is connected to the top of the filter screen framework 110, the connecting arm 150 is movably installed on the filter screen framework 110, and the bottom end of the filter screen 130 is connected to the connecting arm 150. When the filter screen framework 110 slides to the first position at the bottom end of the filter screen framework 110, the connecting arm 150 can pull and unfold the filter screen 130, so that the filter screen 130 is arranged on one side of the filter screen framework 110, thereby filtering dust during use. When the filter screen 130 is cleaned, the connecting arm 150 is slid to the second position at the top of the filter screen framework 110, and the connecting arm 150 folds the bottom end of the filter screen 130 towards the top of the filter screen framework 110, so that the side of the filter screen framework 110 on which the filter screen 130 is arranged is exposed, and the side of the filter screen 130 which is attached to the filter screen framework 110 is exposed. In this way, the filter screen 130 and the filter screen framework 110 are prevented from blocking each other during cleaning, so that the filter screen assembly 100 is more convenient to clean.
