[0039] The present invention provides an air-conditioning indoor unit, which can conveniently realize the installation of an electrostatic dust removal module and improve the stability of the electrostatic dust removal module and the air-conditioning indoor unit after installation.

[0040] In the embodiment of the present invention, Figures 1 to 9As shown, the air-conditioning indoor unit includes an indoor unit body 100, an electrostatic dust removal module 200 and a stopper 300. A mounting frame 110 is provided on the top of the indoor unit body 100. An air inlet is provided on the mounting frame 110. The electrostatic dust removal module 200 is installed on the air inlet. A pull-out opening for disassembling and assembling the electrostatic dust removal module 200 is provided on the front side of the mounting frame 110. The stopper 300 is movably arranged on the mounting frame 110 around the pull-out opening. The stopper 300 has a first state and a second state. When the stopper 300 is in the first state, the stopper 300 stops the electrostatic dust removal module 200 to prevent the electrostatic dust removal module 200 from detaching from the pull-out opening. When the stopper 300 is in the second state, the electrostatic dust removal module 200 can be pulled out through the pull-out opening.

[0041] Specifically, the indoor unit body 100 includes a front panel, a back panel, a left end cover, a right end cover and a mounting frame 110. The bottom of the front panel is provided with an air outlet, and the mounting frame 110 is arranged at the top of the indoor unit body 100. The mounting frame 110 includes a supporting edge and a back edge plate, a left side plate and a right side plate extending upward from the supporting edge. The air inlet is formed in the middle of the supporting edge, and the drawer port is formed on the front side of the mounting frame 110. When the electrostatic dust removal module 200 is completely installed in the mounting frame 110, the electrostatic dust removal module 200 is arranged opposite to the air inlet, so that the air flowing into the indoor unit body 100 through the air inlet can be purified by the electrostatic dust removal module 200 first.

[0042] Since the front side of the installation frame 110 of the air conditioner indoor unit is provided with a drawer opening for the electrostatic dust removal module 200 to be installed, the electrostatic dust removal module 200 can be pushed into or pulled out of the installation frame 110 through the drawer opening, so the installation method of the electrostatic dust removal module 200 is very simple. More importantly, the installation frame 110 of the air conditioner indoor unit proposed in this patent is also provided with a stopper 300, and the stopper 300 has a first state of being stopped at the drawer opening, so that when the electrostatic dust removal module 200 is installed in the installation frame 110, the stopper 300 can prevent the electrostatic dust removal module 200 from being separated from the drawer opening, so that the electrostatic dust removal module 200 can be firmly connected to the indoor unit body 100.

[0043] For details, please refer to Figures 7 to 9 In the first embodiment of the present patent, the stop member 300 includes a pivot portion 310 and a clamping portion 320 fixedly connected to the pivot portion 310, and a mounting edge is extended downwardly from the mounting frame 110, and a pivot hole is provided on the mounting edge for the pivot portion 310 to adapt to pivot connection, and the clamping portion 320 can rotate within the plane where the front side of the mounting frame 110 is located to make the stop member 300 be in the first state or the second state.

[0044] Furthermore, an arc-shaped baffle 210 is provided on the front side wall of the electrostatic dust removal module 200, and an arc-shaped slot 321 is opened on the clamping portion 320. When the stopper 300 is in the first state, the clamping portion 320 is adapted to be clamped with the arc-shaped baffle 210.

[0045] Specifically, the clamping portion 320 is arranged in a long strip shape, one end of the clamping portion 320 is fixedly connected to one end of the pivotal portion 310, and the extension direction of the clamping portion 320 is perpendicular to the axial direction of the pivotal portion 310, so that the clamping portion 320 has a horizontal state flush with the installation edge and a vertical state perpendicular to the installation edge, when the clamping portion 320 rotates from the horizontal state to the vertical state, the clamping groove of the clamping portion 320 is adapted and fixed to the arc-shaped baffle 210, and the clamping component 300 is in the first state, so that the clamping portion 320 can not only limit the upward movement of the electrostatic dust removal module 200, but also limit the outward movement of the electrostatic dust removal module 200 through the pull-out opening, thereby ensuring that the electrostatic dust removal module 200 is firmly connected to the indoor unit body 100.

[0046] As a preferred embodiment, the arc length of the arc baffle 210 is greater than the arc length of the arc slot 321, so that the clamping portion 320 is not easy to separate from the arc baffle 210, thereby ensuring that the clamping portion 300 and the arc baffle 210 remain firmly connected when the air conditioner indoor unit vibrates.

[0047] Furthermore, in order to facilitate the insertion of the pivoting part 310 into the pivoting hole, in one embodiment of the present invention, the pivoting part 310 is provided in a hollow cylindrical structure, and a plurality of cutout grooves extending along its axial direction are provided on the pivoting part 310 at intervals. In this way, the radial dimension of the pivoting part 310 can change. During the insertion of the pivoting part 310 into the pivoting hole, the pivoting part 310 can be reduced in diameter under the extrusion of the pivoting hole, thereby entering the pivoting hole; after the pivoting part 310 is inserted into the pivoting hole, the outer wall of the pivoting part 310 can ensure good contact with the inner wall of the pivoting hole, thereby ensuring that the clamping part 300 and the pivoting hole are always well connected. Preferably, the opening of the pivoting hole is chamfered, so that the pivoting part 310 can be easily inserted into the pivoting hole.

[0048] Furthermore, in order to prevent the pivoting portion 310 from being separated from the pivoting hole, a limiting portion 311 is provided at the end of the pivoting portion 310, and the limiting portion 311 is extended outwardly along the radial direction of the pivoting portion 310. In this way, when the pivoting portion 310 is inserted into the pivoting hole, the limiting portion 311 can prevent the pivoting portion 310 from being separated from the pivoting hole.

[0049] Furthermore, to facilitate the entry of the limiting portion 311 into the pivot hole, the outer diameter of the limiting portion 311 is gradually reduced in the direction away from the clamping portion 320, so that the limiting portion 311 can form a guide surface for the pivoting portion 310 to be inserted into the pivot hole, thereby facilitating the installation of the clamping portion 300 and the pivot hole. When the limiting portion 311 is inserted into the pivot hole, the diameter of the pivoting portion 310 can be reduced, facilitating the entry of the pivoting portion 310 into the pivot hole, and when the limiting portion 311 is fully inserted into the pivot hole, the diameter of the pivoting portion 310 is restored, so that the rod of the pivoting portion 310 is located in the pivot hole, and the head of the pivoting portion 310 (i.e., the limiting portion 311) abuts against the rear wall of the installation frame, thereby preventing the clamping portion 300 from being separated from the pivot hole during rotation.

[0050] Furthermore, in order to keep the clamping part 300 in a vertical position, in one embodiment of the present invention, a positioning column 120 is further provided on the mounting frame 110 around the drawer opening, and a positioning groove 322 adapted to the positioning column 120 is provided on the clamping part 320, so that when the clamping part 300 rotates to a vertical position, the positioning column 120 is adapted to be inserted into the positioning groove 322 on the clamping part 320, so that the clamping part 300 can be kept in a vertical position and abnormal rotation of the clamping part 300 can be avoided. As a preferred embodiment, the end of the positioning column 120 is spherically arranged, and the positioning groove 322 is flared, so that the positioning column 120 can be easily inserted into the positioning groove 322.

[0051] Please refer to Figures 13 to 17 In the second embodiment of the present patent, the stopper 300' includes a sliding portion 310' and a stopper 320' fixedly connected to the sliding portion 310', and a slide groove for the sliding portion 310' to be adapted and installed is provided on the front side of the mounting frame 110, and the sliding portion 310' can slide in the slide groove so that the stopper 320' stops at the drawer opening or avoids the drawer opening.

[0052] Specifically, the sliding portion 310 ′ can slide in a vertical direction or in a horizontal direction; as a preferred embodiment, a protrusion is further provided on the stopper 300 ′ to facilitate the user to push the sliding portion.

[0053] Furthermore, in order to ensure that the stopper 300' can be firmly connected to the electrostatic dust removal module 200 when it is in the first state, in one embodiment of the present invention, a fixing member 210' is provided on the front side wall of the electrostatic dust removal module 200, and when the stopper 300' is in the first state, the stopper 320' is adapted and fixed to the fixing member 210'. Specifically, a protrusion or a groove may be provided on the fixing member 210', and correspondingly, a groove adapted to the protrusion or a protrusion adapted to the groove may be provided on the stopper 320'.

[0054] For further information, please refer to Figure 6 and Figure 7 , considering that the stopper 300 only realizes the limit fixation of the front side of the electrostatic dust removal module 200, in order to maintain the stability of the overall structure, a fixing structure is further provided between the rear wall surface of the electrostatic dust removal module 200 and the installation frame 110. Specifically, a plug hole is provided on the rear wall surface of the installation frame 110 opposite to the drawer port, and the electrostatic dust removal module 200 is provided with a plug block 220 adapted to the plug hole, so that when the plug block 220 is inserted into the plug hole, the rear side of the electrostatic dust removal module 200 can be limited to move upward, and at the same time, when the stopper 300 is rotated to the vertical position, the stopper 300 can be adapted and engaged with the arc-shaped blocking piece 210, thereby limiting the front side of the electrostatic dust removal module 200 from moving upward, so that both the front and rear sides of the electrostatic dust removal module 200 can be limited, thereby effectively preventing the electrostatic dust removal module 200 from moving upward.

[0055] As a preferred embodiment, the plug block 220 and the arc-shaped baffle 210 are staggered in the length direction of the electrostatic dust removal module 200. In this way, the front and rear sides of the electrostatic dust removal module 200 can be evenly stressed, thereby further improving the stability of the electrostatic dust removal module 200 and the indoor unit body 100 after installation.

[0056] For further information, please refer to Figure 1 , Figure 2 , Figures 10 to 12 The air conditioner indoor unit proposed in this patent further includes an upper panel 400 covering the front side of the electrostatic dust removal module 200, and the upper panel 400 is detachably connected to the installation frame 110. After the electrostatic dust removal module 200 and the installation frame 110 are installed, the upper panel 400 can cover the drawer opening, so that the upper panel 400 can cover the front side of the electrostatic dust removal module 200, making the structure of the air conditioner indoor unit more compact.

[0057] Further, in this embodiment, the upper panel 400 and the electrostatic dust removal module 200 are fixed by a snap-fit ​​structure, wherein a hook portion 410 and a buckle portion 420 are provided on the side of the upper panel 400 facing the electrostatic dust removal module 200, a first card slot 130 for the card slot 410 to be adapted and connected is provided on the installation frame 110, and a second card slot 230 for the buckle portion 420 to be adapted and connected is provided on the electrostatic dust removal module 200. Specifically, the first card slot 130 is formed by a card slot convexly provided on the installation edge; the second card slot 230 is a card hole opened on the front side of the electrostatic dust removal module 200.

[0058] In this embodiment, the hook portion 410 and the buckle portion 420 are correspondingly arranged at the lower side of the buckle portion, and multiple pairs of hook portions 410 and buckle portions 420 are arranged at intervals in the extension direction of the upper panel 400, so that the structural strength of the upper panel 400 after being fixed to the installation frame 110 can be improved. As a preferred mode, the top of the first slot 130 is flared, so that the hook portion 410 can be easily inserted into the first slot 130; in addition, the hook portion 410 is L-shaped, and the hook portion 410 extends downward, the buckle portion 420 is convexly arranged upward to form a convex buckle, and the buckle portion 420 and the hook portion 410 are arranged in back to back, so that the stability of the upper panel 400 and the indoor unit body 100 after installation can be improved. Further, the upper panel 400 is smoothly connected to the front panel of the air conditioner indoor unit, so that the external structure of the air conditioner indoor unit is more compact and beautiful.

[0059] For further information, please refer to Figure 4 and Figure 5 A power supply spring sheet 140 is provided on the inner side wall of the installation frame 110, and the electrostatic dust removal module 200 is provided with a power supply electrode sheet adapted to the power supply spring sheet 140, and the power supply spring sheet 140 is bent to form a contact portion protruding toward the power supply electrode sheet. In this way, when the electrostatic dust removal module 200 is installed in the installation frame 110, the power supply electrode sheet of the electrostatic dust removal module 200 can be electrically connected to the power supply spring sheet 140. In this way, the connection of the power supply line of the electrostatic dust removal module 200 can be completed during the structural installation process, thereby improving the assembly efficiency of the air-conditioning indoor unit.

[0060] More importantly, since the power supply spring 140 extends in the front-to-back direction, which is the same direction as the direction of pushing in or pulling out the electrostatic dust removal module 200, when the electrostatic dust removal module 200 is installed, the end of the electrostatic dust removal module 200 can be in close contact with the protruding contact part of the power supply spring 140, thereby ensuring the stability of the power supply connection of the electrostatic dust removal module 200.

[0061] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
