DETAILED DESCRIPTION

[0054] The existing decorative panels are directly installed on the middle frame through buckles, and the disassembly and assembly of the decorative panels is not intuitive, and the user's perception is weak, and it is not possible to intuitively find that the decorative panels can be removed. Moreover, after assembly, it is impossible to confirm that all buckles are assembled in place, which leads to poor user experience. Moreover, after multiple disassembly and assembly, the buckles are prone to wear and deformation, or directly break, and lose the assembly effect.

[0055] To solve the above problems, please refer to Figure 1 This embodiment provides an air conditioner, which includes an outdoor unit and an indoor unit, which are connected by a heat exchange pipe. The indoor unit is provided with a movable slider on the decorative panel so that the user can intuitively feel that the decorative panel is detachable, and it is not easy to be damaged compared to the buckle connection, and the installation stability is higher.

[0056] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0057] Please refer to Figure 1 and Figure 2 The present embodiment provides an indoor unit 100, which includes a middle frame 110, a decorative panel 130 and a slide buckle 150. An inspection port 111 is provided at the bottom of the middle frame 110, so that when the indoor unit 100 is hung on a wall, the pipeline can be connected and inspected through the inspection port 111. The decorative panel is provided with a hook buckle 131 and a mounting groove 133. The slide buckle 150 is movably mounted in the mounting groove 133. The middle frame 110 is provided with an abutment portion 113 matched with the slide buckle 150 and a card slot 115 matched with the hook buckle 131. The decorative panel 130 is mounted on the middle frame 110, and the hook buckle 131 is clamped to the middle frame 110 through the card slot 115. The slide buckle 150 is moved along the locking direction of the mounting groove 133, and the slide buckle 150 can abut against the abutment portion 113 to limit the movement of the decorative panel 130. The slide buckle 150 is moved along the unlocking direction of the installation slot 133 , and the slide buckle 150 can be disengaged from the abutment portion 113 , so that the decorative plate 130 can be moved relative to the middle frame 110 , so that the hook buckle 131 is disengaged from the engagement with the slot 115 .

[0058] In this embodiment, a movable slide buckle 150 is provided on the decorative plate 130 to fix the decorative plate 130 and the middle frame 110, so that the user can intuitively feel that the decorative plate 130 is detachable. The hook buckle 131 provided on the decorative plate 130 and the slide buckle 150 cooperate with each other to fix the decorative plate 130 and the middle frame 110. When disassembling or assembling, only the slide buckle 150 needs to be moved to release the fixation, which makes disassembly and installation more convenient, and is not easy to be damaged compared to the buckle connection, and has higher installation stability.

[0059] Secondly, in this embodiment, a decorative panel 130 is provided at the bottom of the middle frame 110 , so that the inspection port 111 can be covered, making the appearance of the indoor unit 100 more complete and beautiful, and preventing dust from entering the indoor unit 100 .

[0060] In this embodiment, the decorative plate 130 is provided with a recessed groove, and the mounting groove 133 is provided on the bottom wall of the recessed groove, so that the outer plane of the slider 150 may not protrude on the appearance surface of the decorative plate 130, making it look better.

[0061] It should also be noted that the locking direction and the unlocking direction can be understood as the two sides of the length direction of the installation groove 133.

[0062] Please refer to Figure 2 , Figure 3 and Figure 4 In this embodiment, the hook 131 includes a connecting column 135 protruding from the inner side of the decorative plate 130 and a clamping portion 137 connected to the connecting column 135. A clamping groove 139 is formed between the clamping portion 137 and the decorative plate 130. The clamping groove 139 is clamped to the middle frame 110 through the clamping groove 115. The clamping portion 137 is protruding toward the installation direction. When the decorative plate 130 is installed on the middle frame 110, the clamping portion 137 can extend into the clamping groove 115, push the decorative plate 130 along the installation direction, and the clamping groove 139 can be clamped to the middle frame 110, and move the slide buckle 150 along the locking direction of the installation groove 133. The slide buckle 150 abuts against the abutting portion 113 to limit the decorative plate 130 from moving toward the removal direction. When the decorative plate 130 is removed from the middle frame 110, the slide buckle 150 is moved along the unlocking direction of the installation groove 133 to disengage the slide buckle 150 from the abutment portion 113, and then the decorative plate 130 can be moved in the removal direction so that the clamping groove 139 can be disengaged from the middle frame 110. The installation direction is opposite to the removal direction.

[0063] The present application utilizes the extension direction of the clamping portion 137 of the hook 131 and the moving direction of the slide 150, so that after the decorative panel 130 is installed in place, the slide 150 moves in the locking direction to abut against the abutment portion 113 of the middle frame 110, thereby limiting the hook 131 from coming out. During disassembly, the slide 150 moves in the unlocking direction, so that the slide 150 can fall off and abut against the middle frame 110, so that the decorative panel 130 can move in the removal direction, so that the hook 131 can be easily disengaged from the middle frame 110, making disassembly and installation more convenient. Secondly, fixing the decorative panel 130 by means of the hook 131 and the slide 150 can make the decorative panel 130 and the middle frame 110 fit better, and the seams are more uniform.

[0064] It should be noted that the hook 131 is first hung on the middle frame 110 by moving the decorative plate 130, and then the sliding buckle 150 is used to restrict the decorative plate 130 from moving in the reverse direction.

[0065] It should be noted that, in the embodiment, the installation direction and the removal direction can be understood as two sides in the width direction of the bottom surface of the middle frame 110 .

[0066] In this embodiment, the installation direction is perpendicular to the locking direction, and the locking direction is opposite to the unlocking direction. Generally, they are located on the same plane.

[0067] In this embodiment, the moving direction of the decorative plate 130 and the moving direction of the slider 150 are set to be perpendicular, so that after the slider 150 is engaged, the fixation of the middle frame 110 and the decorative plate 130 is more stable.

[0068] Of course, in some embodiments of the present application, there may be an angle between the installation direction and the locking direction, such as 45°, 60°, etc., as long as the decorative panel 130 is restricted from moving in the removal direction when abutting against the limiting portion.

[0069] Please continue to refer to Figure 2 , Figure 3 and Figure 4 In this embodiment, the abutment portion 113 is an abutment block 116 disposed on the middle frame 110. An avoidance groove 117 is disposed on the periphery of the abutment block 116. The avoidance groove 117 is an "L"-shaped structure, and its vertical section corresponds to the slider in the unlocking position for avoidance, and the horizontal section corresponds to the locking direction so that the slider 150 can move to the locking position. The removal direction is opposite to the installation direction. When the slider 150 moves toward the locking direction and is located in the locking position, the slider 150 cooperates with the side wall of the abutment block 116 to limit the movement of the decorative plate 130 in the removal direction, so that the hook 131 is clamped to the middle frame 110 through the clamping groove 115. When the slider 150 moves toward the unlocking direction and is located in the unlocking position, the slider 150 corresponds to the avoidance groove 117, so that the decorative plate 130 can move in the removal direction to release the clamping of the hook 131 with the middle frame 110.

[0070] In the embodiment, the abutment portion 113 is set as an abutment block 116 to facilitate the production of the middle frame 110, and an avoidance groove 117 is set on the periphery of the abutment block 116 to avoid the slide buckle 150 when the decorative panel 130 is installed and removed, so as to facilitate the movement of the decorative panel 130 when the slide buckle 150 is in the unlocking direction and unlocking position.

[0071] It should be noted that the locking direction and the locking position correspond to each other, and the unlocking direction and the unlocking position correspond to each other. When the slider moves in the locking direction, it will eventually move to the locking position, and when the slider moves in the unlocking direction, it will eventually move to the unlocking position.

[0072] Of course, in some other embodiments of the present application, the abutment portion 113 may also be a groove, etc., as long as it can abut against the slider 150 to limit the movement of the decorative panel 130 in the removal direction.

[0073] Please refer to Figure 5 and Figure 6 In this embodiment, the slider 150 includes a main body 151 and an abutment column 153 connected to the main body 151. The side wall of the abutment column 153 is recessed with a first limiting groove 155. The abutment column 153 can be movably inserted into the installation groove 133. The side wall of the installation groove 133 formed by the decorative plate 130 is clamped in the first limiting groove 155, and the end of the abutment column 153 extends out of the decorative plate 130 and can abut against the abutment portion 113.

[0074] In this embodiment, the first limiting groove 155 is provided on the abutting column 153 to prevent the sliding buckle 150 from being separated from the decorative plate 130 after being installed on the decorative plate 130 and falling off from the decorative plate 130. This makes assembly more convenient.

[0075] Please refer to Figure 5 and Figure 6 In this embodiment, the slider 150 further includes a guide post 157 protruding from the body 151 at a distance from the abutment post 153. In the locking direction, the abutment post 153 is located in front of the guide post 157. In the unlocking position, the guide post 157 abuts against the end surface of the mounting groove.

[0076] In this embodiment, the side wall of the guide column 157 is provided with a second limiting groove 159, the guide column 157 is movably inserted into the installation groove 133, and the side wall of the installation groove 133 formed by the decorative panel 130 is clamped in the second limiting groove 159, and the first guide inclined surface 161 is provided on both sides of the abutment column 153, and the second guide surface 163 is provided on both sides of the guide column 157.

[0077] Please refer to Figure 7 In this way, when installing the slide buckle 150, one end of the guide column 157 of the slide buckle 150 can be pressed into the installation groove 133 first, and then the other side of the abutment column 153 can be pressed into the installation groove 133 to facilitate the installation of the slide buckle 150. In addition, the guide column 157 is provided in this embodiment to facilitate the guidance of the slide buckle 150 when it is moved and installed, so that the slide buckle 150 can be conveniently installed in the installation of the decorative panel 130.

[0078] It should be noted that, in general, the chamfer of the guide column 157 should be larger and the volume size should be smaller, so that it can be easily installed. Since the side wall of the abutting column 153 needs to abut against the side wall of the installation groove 133 to form a limit, the chamfer of the first guide surface of the abutting column 153 should be smaller to ensure force, so that it can be easily installed.

[0079] Please continue to refer to Figure 5 and Figure 6 In this embodiment, an anti-foolproofing boss 141 is disposed on the outer periphery of the mounting groove 133 , and an anti-foolproofing sliding groove 165 corresponding to the anti-foolproofing boss 141 is disposed on the inner side of the body 151 .

[0080] In this embodiment, the anti-mistake boss 141 and the matching anti-mistake slide groove 165 can avoid the problem of reverse installation of the slide buckle 150.

[0081] Specifically, there are three foolproof bosses 141, one of which is arranged at one side of the end of the mounting groove 133, and the other two are arranged at the outer periphery of both sides of the mounting groove 133, respectively corresponding to the three foolproof slide grooves 165. Only when the slide buckle 150 is installed into the mounting groove 133 according to the preset direction, the foolproof bosses 141 will correspond to the foolproof slide grooves 165 one by one. When assembled in reverse, the first limiting groove 155 and the second limiting groove 159 will not be clamped on the side wall of the mounting groove 133 due to the effect of the foolproof bosses 141.

[0082] Please continue to refer to Figure 5 and Figure 6 In this embodiment, two side walls opposite to each other in the width direction of the mounting groove 133 are both provided with an arc-shaped clamping portion 143 protruding outward. A first limiting groove 147 is provided on the side wall in the length direction of the mounting groove 133 and located on the side of the arc-shaped clamping portion 143 close to the locking position. A second limiting groove 149 is provided on the side wall in the length direction of the mounting groove 133 and located on the side of the arc-shaped clamping portion 143 close to the unlocking position. The slide buckle 150 can move over the arc-shaped clamping portion 143 in the locking direction, so that the slide buckle 150 moves to the locking position. When the slide buckle 150 is in the locking position, the abutting column 153 abuts against the end surface of the mounting groove 133 close to the unlocking direction, and abuts against the abutting portion 113, and the guide column 157 is clamped with the arc-shaped clamping portion 143. The slide buckle 150 can move over the arc-shaped clamping portion 143 in the unlocking direction, so that the slide buckle 150 moves to the unlocking position. When the slide buckle 150 is in the unlocking position, the abutment column 153 and the guide column 157 are located on both sides of the arc-shaped clamping portion 143, and the abutment column 153 is located in the first limiting groove 147, the guide column 157 is located in the second limiting groove 149, and the guide column 157 abuts against the end face of the mounting groove 133 on one side of the unlocking direction.

[0083] In this embodiment, the arc-shaped clamping portion 143 is protruded outwardly on the side wall of the installation groove 133 to limit the slider 150, prevent the slider 150 from moving freely, and increase the damping feeling, so that the user can feel the unlocking or locking. In addition, the arc has a guiding function and can be directed to the abutment column 153 and the guide column 157. The first limiting groove 147 and the second limiting groove 149 can improve the feel of being in place, so that the user can intuitively feel the movement to the unlocking position and the locking position.

[0084] In this embodiment, the arc-shaped clamping portion 143 is thickened to achieve interference fit with the first limiting groove 155 .

[0085] In this embodiment, the arc-shaped clamping portion 143 is thickened to make it interference fit with the first limiting groove 155, which will increase the damping feeling and allow the user to clearly feel the damping feeling during the sliding process, so that the user knows that the slider 150 has passed the critical point and the slider 150 can be prevented from moving freely.

[0086] In this embodiment, a thinning groove 145 is formed on the outer periphery of the arc-shaped clamping portion 143 .

[0087] In this embodiment, a thinning groove 145 is provided on the outer periphery of the arc-shaped clamping portion 143 , so that the arc-shaped clamping portion 143 can be deformed more easily and have elasticity.

[0088] Secondly, reinforcing ribs are provided at positions corresponding to the thinning groove 145 and the arc-shaped clamping portion 143 , thereby preventing the sliding buckle 150 from being broken due to excessive force when inserted.

[0089] Secondly, in order to facilitate pushing the slider 150, the surface of the body 151 is roughened to form an uneven texture to increase friction. In addition, unlocking and locking indicators are respectively provided on both sides of the installation slot 133 to facilitate telling the user which direction to push.

[0090] In summary, the working principles and beneficial effects of the air conditioner and indoor unit 100 provided by the embodiment of the present invention include:
