[0002] In some indoor units, in order to facilitate the installation of the liquid inlet pipe, the gas outlet pipe and the maintenance, an opening is arranged at the bottom of the middle frame to ensure that the indoor unit is conveniently installed with the liquid inlet pipe, the gas outlet pipe and the maintenance after being installed on the wall, and a detachable decorative plate is arranged at the bottom of the middle frame to ensure the appearance of the indoor unit and prevent dust from entering.

[0003] The existing decorative plate is directly installed on the middle frame through buckles, and the disassembly and assembly effect of the decorative plate is not intuitive, the user's perception is weak, and the user cannot intuitively find that the decorative plate can be disassembled. Moreover, after assembly, it is impossible to confirm that all buckles are assembled in place, the user experience is poor, and after multiple disassembly and assembly, the buckles are prone to wear and deformation, or directly break, losing the assembly effect. SUMMARY

[0004] The problem solved by the present application is that the existing decorative plate is directly installed on the middle frame through buckles, the disassembly and assembly effect of the decorative plate is not intuitive, the user's perception is weak, and the user cannot intuitively find that the decorative plate can be disassembled. Moreover, after assembly, it is impossible to confirm that all buckles are assembled in place, the user experience is poor, and after multiple disassembly and assembly, the buckles are prone to wear and deformation, or directly break, losing the assembly effect.

[0005] To solve the above problems, the present application provides an indoor unit and an air conditioner, which are characterized in that a movable buckle is arranged on the decorative plate, so that the user can intuitively feel that the decorative plate can be disassembled, and the buckle connection is not easy to damage, and the installation stability is higher.

[0006] In a first aspect, the present application provides an indoor unit, which comprises a middle frame, a decorative plate and a buckle.

[0007] The decorative plate is provided with a hook buckle and a mounting groove.

[0008] The buckle is movably mounted in the mounting groove.

[0009] The middle frame is provided with an abutting portion matched with the buckle and a clamping groove matched with the hook buckle.

[0010] The decorative plate is mounted on the middle frame, and the hook buckle is clamped on the middle frame through the clamping groove.

[0011] The buckle is moved along the locking direction of the mounting groove, and the buckle can abut against the abutting portion to limit the movement of the decorative plate.

[0012] Move the sliding buckle along the unlocking direction of the mounting groove. The sliding buckle can disengage from the abutment part, allowing the decorative panel to move relative to the middle frame, so that the hook can disengage from the slot.

[0013] This application uses movable sliding fasteners on the decorative panel to secure it to the mid-frame, allowing users to intuitively perceive that the decorative panel is removable. Furthermore, the decorative panel is secured to the mid-frame through a combination of hooks and sliding fasteners. During assembly and disassembly, simply moving the sliding fasteners releases the fastener, making disassembly and installation more convenient. Compared to snap-fit ​​connections, this method is less prone to damage and offers higher installation stability.

[0014] In an optional embodiment, the hook includes a connecting post protruding from the inner side of the decorative panel and a snap-fit ​​portion connected to the connecting post, the snap-fit ​​portion protruding in the installation direction;

[0015] When the decorative panel is installed on the middle frame, the snap-fit ​​part of the decorative panel can be snapped into the middle frame by pushing it along the installation direction, and the sliding buckle can be moved along the locking direction of the mounting groove. The sliding buckle abuts against the abutting part to restrict the decorative panel from moving in the removal direction.

[0016] When the decorative panel is removed from the middle frame, the sliding buckle is moved along the unlocking direction of the mounting groove to disengage the sliding buckle from the abutting part. Then the decorative panel can be moved in the removal direction so that the snap-fit ​​groove can disengage from the middle frame.

[0017] The installation direction is opposite to the removal direction.

[0018] This application utilizes the extension direction of the hook's locking portion and the movement direction of the sliding buckle. After the decorative panel is installed, the sliding buckle moves in the locking direction to abut against the abutment portion of the middle frame, thus preventing the hook from detaching. During disassembly, the sliding buckle moves in the unlocking direction, allowing it to detach from the middle frame and abut against it, enabling the decorative panel to move in the removal direction. This facilitates easy detachment of the hook from the middle frame, making disassembly and installation more convenient.

[0019] In an optional implementation, the installation direction is perpendicular to the locking direction, and the locking direction is opposite to the unlocking direction.

[0020] This implementation sets the movement direction of the decorative panel and the movement direction of the sliding buckle to be perpendicular, which makes the fixation of the middle frame and the decorative panel more stable after the sliding buckle is engaged.

[0021] In an optional embodiment, the abutting part is an abutting block disposed on the middle frame, and the abutting block is provided with a relief groove on its periphery;

[0022] When the sliding buckle moves toward the locking direction and is in the locking position, the sliding buckle abuts against the abutting block to restrict the decorative panel from moving toward the removal direction;

[0023] When the sliding buckle moves in the unlocking direction and is in the unlocking position, the sliding buckle corresponds to the clearance groove, allowing the decorative panel to move in the removal direction to release the hook from the middle frame.

[0024] The application proposes to make the abutment part into an abutment groove to facilitate the production of the middle frame. The avoidance groove connected to the abutment groove can avoid the sliding buckle when the decorative panel is installed and removed, so as to facilitate the movement of the decorative panel when the sliding buckle is in the unlocking position in the unlocking direction.

[0025] In an optional embodiment, the sliding buckle includes a body and an abutment post connected to the body, wherein a first limiting groove is recessed in the side wall of the abutment post;

[0026] The abutment post is movably inserted into the mounting groove, the decorative panel forming the side wall of the mounting groove is engaged with the first limiting groove, and the end of the abutment post extends out of the decorative panel and can abut against the abutment part in the locked position.

[0027] The first limiting groove provided in this application can prevent the clip from falling off the decorative panel, making assembly more convenient.

[0028] In an optional embodiment, the sliding buckle further includes a guide post that protrudes from the body at a distance from the abutment post. In the locking direction, the abutment post is located in front of the guide post, and the guide post is used to abut against the end face of the mounting groove when in the unlocked position.

[0029] In this embodiment, guide posts are provided to facilitate the movement and installation of the slider, so that the slider can be easily installed within the decorative panel.

[0030] In an optional embodiment, a foolproof protrusion is provided on the outer periphery of the mounting groove, and a foolproof groove corresponding to the foolproof protrusion is provided on the inner side of the body.

[0031] This application features a foolproof protrusion and a matching foolproof groove to prevent the reverse installation of the clips.

[0032] In an optional embodiment, both sidewalls of the mounting groove facing each other in the width direction are provided with arc-shaped snap-fit ​​portions protruding outwards;

[0033] A first limiting groove is provided on the side wall along the length of the mounting groove, and on the side of the arc-shaped snap-fit ​​portion near the locking position.

[0034] A second limiting groove is provided on the side wall along the length of the mounting groove, and on the side of the arc-shaped snap-fit ​​portion near the unlocking position.

[0035] The sliding buckle can move along the locking direction to pass over the arc-shaped latching portion, so that the sliding buckle moves to the locking position;

[0036] When the sliding buckle is in the locked position, the abutting post abuts against the end face of the mounting groove near the unlocking direction and abuts against the abutting part, and the guide post is engaged with the arc-shaped locking part;

[0037] The sliding buckle can move along the unlocking direction to pass over the arc-shaped latching part, so that the sliding buckle moves to the unlocking position;

[0038] When the sliding buckle is in the unlocked position, the abutment post and the guide post are located on both sides of the arc-shaped locking part, and the abutment post is located in the first limiting groove, the guide post is located in the second limiting groove, and the guide post abuts against the end face of the mounting groove on one side of the unlocking direction.

[0039] This application utilizes an outwardly protruding arc-shaped locking portion on the side wall of the mounting groove to limit the sliding buckle, preventing it from moving freely and increasing damping, allowing the user to feel the unlocking or locking mechanism. Furthermore, the arc provides a guiding function, allowing the locking and unlocking posts to pass through. Secondly, the inclusion of a first and second limiting groove enhances the tactile feedback of the lever.

[0040] In an optional embodiment, the arc-shaped snap-fit ​​portion is interference-fitted with the first limiting groove.

[0041] In this embodiment, the arc-shaped locking part is thickened to make it interference fit with the first limiting groove. This increases the damping sensation, allowing the user to feel the sliding buckle passing the critical point, and prevents the sliding buckle from moving freely.

[0042] In an optional embodiment, a thinning groove is formed on the outer periphery of the arc-shaped snap-fit ​​portion.

[0043] This application provides a thinning groove on the outer periphery of the arc-shaped snap-fit ​​part, thereby making the arc-shaped snap-fit ​​part easier to deform and more elastic.

[0044] Secondly, embodiments of the present invention also provide an air conditioner, which includes an outdoor unit and an indoor unit as described in any of the above optional embodiments, wherein the indoor unit and the outdoor unit are connected by a heat exchange pipe.

[0045] The air conditioner provided in this application uses movable sliding fasteners on the decorative panel to fix the panel to the middle frame, allowing users to intuitively perceive that the decorative panel is removable. Furthermore, the decorative panel is fixed to the middle frame by a combination of hooks and sliding fasteners. During disassembly and assembly, simply moving the sliding fasteners releases the fastener, making disassembly and installation more convenient. Compared to snap-fit ​​connections, this method is less prone to damage and offers higher installation stability. Attached Figure Description

Detailed Implementation

[0054] The existing decorative panels are directly installed on the middle frame using clips. The installation and removal of the decorative panels are not intuitive, and users have little awareness of their ability to remove them. Furthermore, it is impossible to confirm that all clips are properly in place after assembly, resulting in a poor user experience. After repeated installation and removal, the clips are prone to wear, deformation, or even breakage, rendering the assembly ineffective.

[0055] To solve the above problem, please refer to Figure 1 This embodiment provides an air conditioner, which includes an outdoor unit and an indoor unit connected by a heat exchange pipe. The indoor unit features movable sliding fasteners on its decorative panel, allowing users to intuitively perceive that the panel is removable. Compared to snap-fit ​​connections, this design is less prone to damage and offers higher installation stability.

[0056] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0057] Please refer to Figure 1 and Figure 2 This embodiment provides an indoor unit 100, which includes a middle frame 110, a decorative panel 130, and a sliding latch 150. The bottom of the middle frame 110 is provided with an access port 111 for connecting pipes and performing maintenance when the indoor unit 100 is suspended from the wall. The decorative panel is provided with a hook 131 and a mounting groove 133. The sliding latch 150 is movably mounted in the mounting groove 133. The middle frame 110 is provided with an abutment portion 113 that mates with the sliding latch 150 and a locking groove 115 that mates with the hook 131. The decorative panel 130 is mounted on the middle frame 110, and the hook 131 is engaged with the middle frame 110 via the locking groove 115. Moving the sliding latch 150 along the locking direction of the mounting groove 133 allows it to abut against the abutment portion 113, thus restricting the movement of the decorative panel 130. Move the sliding buckle 150 along the unlocking direction of the mounting groove 133. The sliding buckle 150 can disengage from the abutment part 113, so that the decorative panel 130 can move relative to the middle frame 110, so that the hook 131 disengages from the slot 115.

[0058] In this embodiment, a movable sliding buckle 150 is provided on the decorative panel 130 to fix the decorative panel 130 to the middle frame 110, allowing the user to intuitively perceive that the decorative panel 130 is detachable. Furthermore, the decorative panel 130 is fixed to the middle frame 110 by the cooperation of hooks 131 and sliding buckles 150. During disassembly and assembly, simply moving the sliding buckle 150 is sufficient to release the fixation, making disassembly and installation more convenient. Compared to snap-fit ​​connections, this method is less prone to damage and offers higher installation stability.

[0059] Secondly, in this embodiment, a decorative panel 130 is provided at the bottom of the middle frame 110, which can cover the access panel 111, making the appearance of the indoor unit 100 more complete and beautiful, and can also prevent dust from entering the indoor unit 100.

[0060] In this embodiment, the decorative panel 130 is provided with a recessed groove, and the mounting groove 133 is provided on the bottom wall of the recessed groove. In this way, the outer surface of the sliding buckle 150 does not protrude outward from the outer surface of the decorative panel 130, making it look better.

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

[0062] Please refer to Figure 2 , Figure 3 and Figure 4 In this embodiment, the hook 131 includes a connecting post 135 protruding from the inner side of the decorative panel 130 and a snap-fit ​​portion 137 connected to the connecting post 135. A snap-fit ​​groove 139 is formed between the snap-fit ​​portion 137 and the decorative panel 130. The snap-fit ​​groove 139 is snapped into the middle frame 110 through a snap-fit ​​groove 115. The snap-fit ​​portion 137 protrudes in the installation direction. When the decorative panel 130 is installed on the middle frame 110, the snap-fit ​​portion 137 can extend into the snap-fit ​​groove 115. Pushing the decorative panel 130 along the installation direction allows the snap-fit ​​groove 139 to snap into the middle frame 110. The sliding buckle 150 moves along the locking direction of the mounting groove 133. The sliding buckle 150 abuts against the abutment portion 113 to restrict the movement of the decorative panel 130 in the removal direction. When the decorative panel 130 is removed from the middle frame 110, the sliding buckle 150 is moved along the unlocking direction of the mounting groove 133, allowing the sliding buckle 150 to disengage from the abutment part 113. Afterward, the decorative panel 130 can be moved in the removal direction so that the snap-fit ​​groove 139 can disengage and snap into the middle frame 110. The installation direction is opposite to the removal direction.

[0063] This application utilizes the extending direction of the snap-fit ​​portion 137 of the hook 131 and the moving direction of the sliding buckle 150. After the decorative panel 130 is installed, the sliding buckle 150 moves in the locking direction to abut against the abutment portion 113 of the middle frame 110, thus preventing the hook 131 from disengaging. During disassembly, the sliding buckle 150 moves in the unlocking direction, allowing it to detach from the middle frame 110 and move in the removal direction, making it easier for the hook 131 to detach from the middle frame 110, thus facilitating both disassembly and installation. Furthermore, using the hook 131 and sliding buckle 150 to fix the decorative panel 130 allows for a better fit between the decorative panel 130 and the middle frame 110, resulting in more even seams.

[0064] It should be noted that the decorative panel 130 is first moved to hook the hook 131 onto the middle frame 110, and then the sliding buckle 150 is used to restrict the decorative panel 130 from moving in the opposite direction.

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

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

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

[0068] Of course, in some embodiments of this application, there can be an angle between the installation direction and the locking direction, such as 45°, 60°, etc., as long as it restricts the movement of the decorative panel 130 in the removal direction when it abuts against the limiting part.

[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. A clearance groove 117 is provided around the periphery of the abutment block 116. The clearance groove 117 has an "L"-shaped structure; its vertical section corresponds to the sliding buckle in the unlocked position for clearance, and its horizontal section corresponds to the locking direction, allowing the sliding buckle 150 to move to the locked position. The removal direction is opposite to the installation direction. When the sliding buckle 150 moves towards the locking direction and is in the locked position, the sliding buckle 150 cooperates with the side wall of the abutment block 116 to restrict the decorative panel 130 from moving towards the removal direction, so that the hook 131 is engaged with the middle frame 110 through the slot 115. When the sliding buckle 150 moves towards the unlocking direction and is in the unlocked position, the sliding buckle 150 corresponds to the clearance groove 117, allowing the decorative panel 130 to move towards the removal direction, thereby releasing the hook 131 from the middle frame 110.

[0070] In this embodiment, by setting the abutment portion 113 as an abutment block 116, it is easier to manufacture the middle frame 110. The abutment block 116 provides a clearance groove 117 around its periphery to avoid the sliding buckle 150 when the decorative panel 130 is installed and removed, so as to facilitate the movement of the decorative panel 130 when the sliding buckle 150 is in the unlocking position in the unlocking direction.

[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. When the slider moves in the unlocking direction, it will eventually move to the unlocking position.

[0072] Of course, in other embodiments of this application, the abutment portion 113 may also be a groove or the like, as long as it can abut against the sliding buckle 150 to restrict the decorative panel 130 from moving in the removal direction.

[0073] Please refer to Figure 5 and Figure 6 In this embodiment, the sliding buckle 150 includes a body 151 and an abutment post 153 connected to the body 151. The side wall of the abutment post 153 is recessed with a first limiting groove 155. The abutment post 153 is movably inserted into the mounting groove 133. The side wall of the decorative plate 130 forming the mounting groove 133 is engaged with the first limiting groove 155, and the end of the abutment post 153 extends out of the decorative plate 130 and can abut against the abutment part 113.

[0074] In this embodiment, by providing a first limiting groove 155 on the abutment post 153, the sliding buckle 150 can be prevented from separating from the decorative panel 130 after installation, thus avoiding detachment from the decorative panel 130. This makes assembly more convenient.

[0075] Please refer to Figure 5 and Figure 6 In this embodiment, the sliding buckle 150 also includes a guide post 157 that protrudes from the body 151 at a distance from the abutment post 153, with the abutment post 153 located in front of the guide post 157 in the locking direction. In the unlocked position, the guide post 157 abuts against the end face of the mounting groove.

[0076] In this embodiment, the side wall of the guide post 157 is provided with a second limiting groove 159, the guide post 157 is movably inserted into the mounting groove 133, and the side wall of the decorative plate 130 forming the mounting groove 133 is engaged with the second limiting groove 159. Both sides of the abutting post 153 are provided with a first guide slope 161, and both sides of the guide post 157 are provided with a second guide surface 163.

[0077] Please refer to Figure 7 In this way, when installing the sliding buckle 150, one end of the guide post 157 of the sliding buckle 150 can be pressed into the mounting groove 133 first, and then the other side of the abutment post 153 can be pressed into the mounting groove 133 to facilitate the installation of the sliding buckle 150. In this embodiment, the guide post 157 is set to facilitate the guidance when the sliding buckle 150 moves and during installation, so that the sliding buckle 150 can be easily installed in the mounting of the decorative panel 130.

[0078] It should be noted that, generally, the chamfer of the guide post 157 should be larger and its size smaller to facilitate installation. However, since the side wall of the abutment post 153 needs to abut against the side wall of the mounting groove 133 to form a limiting contact, the chamfer of the first guide surface of the abutment post 153 should be smaller to ensure force bearing, thus facilitating installation.

[0079] Please continue to refer to Figure 5 and Figure 6 In this embodiment, a foolproof protrusion 141 is provided on the outer periphery of the mounting groove 133, and a foolproof groove 165 corresponding to the foolproof protrusion 141 is provided on the inner side of the body 151.

[0080] In this embodiment, the anti-foolproof boss 141 and the matching anti-foolproof groove 165 are provided to prevent the problem of the sliding buckle 150 being installed backwards.

[0081] Specifically, there are three anti-misalignment protrusions 141. One is located on one side of the end of the mounting groove 133, and the other two are located on the outer periphery of both sides of the mounting groove 133, corresponding to the three anti-misalignment grooves 165 respectively. Only when the sliding buckle 150 is inserted into the mounting groove 133 in the preset direction will the anti-misalignment protrusion 141 correspond one-to-one with the anti-misalignment groove 165. When the assembly is reversed, the anti-misalignment protrusions 141 prevent the first limiting groove 155 and the second limiting groove 159 from getting stuck on the side wall of the mounting groove 133.

[0082] Please continue to refer to Figure 5 and Figure 6 In this embodiment, the two opposite sidewalls of the mounting groove 133 in the width direction are each provided with an outwardly protruding arc-shaped locking portion 143. A first limiting groove 147 is provided on the sidewall of the mounting groove 133 in the length direction, near the locking position of the arc-shaped locking portion 143. A second limiting groove 149 is provided on the sidewall of the mounting groove 133 in the length direction, near the unlocking position of the arc-shaped locking portion 143. The sliding buckle 150 can move past the arc-shaped locking portion 143 in the locking direction to move to the locking position. When the sliding buckle 150 is in the locking position, the abutment post 153 abuts against the end face of the mounting groove 133 near the unlocking direction and also abuts against the abutment portion 113, and the guide post 157 engages with the arc-shaped locking portion 143. The sliding buckle 150 can move past the arc-shaped locking portion 143 in the unlocking direction to move to the unlocking position. When the sliding buckle 150 is in the unlocked position, the abutment post 153 and the guide post 157 are located on both sides of the arc-shaped locking part 143, and the abutment post 153 is located in the first limiting groove 147, the guide post 157 is located in the second limiting groove 149, and the guide post 157 abuts against the end face of the mounting groove 133 on the side of the unlocking direction.

[0083] In this embodiment, an arc-shaped latching part 143 protrudes outward from the side wall of the mounting groove 133, which limits the sliding buckle 150, preventing it from moving freely and increasing the damping feel, allowing the user to feel the unlocking or locking. Furthermore, the arc has a guiding function, allowing the latch to abut against the post 153 and guide post 157. The design of the first limiting groove 147 and the second limiting groove 149 enhances the tactile feedback, allowing the user to intuitively feel the movement to the unlocked and locked positions.

[0084] In this embodiment, the arc-shaped snap-fit ​​portion 143 is thickened to allow for an interference fit with the first limiting groove 155.

[0085] In this embodiment, the arc-shaped latching part 143 is thickened so that it is interference-fitted with the first limiting groove 155. This increases the damping feel, allowing the user to clearly feel the damping during the sliding process, so that the user knows that the sliding buckle 150 has passed the critical point, and can prevent the sliding buckle 150 from moving freely.

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

[0087] In this embodiment, by providing a thinning groove 145 on the outer periphery of the arc-shaped snap-fit ​​portion 143, the arc-shaped snap-fit ​​portion 143 can be more easily deformed and have elasticity.

[0088] Secondly, reinforcing ribs are provided at the positions corresponding to the thinning groove 145 and the arc-shaped snap-fit ​​part 143, so as to avoid excessive force and breakage when the sliding buckle 150 is inserted.

[0089] Secondly, to facilitate the sliding latch 150, the outer surface of the body 151 is roughened to create an uneven texture, thus increasing friction. Furthermore, unlocking and locking indicators are provided on both sides of the mounting groove 133 to inform the user which direction to push.

[0090] In summary, the working principle and beneficial effects of the air conditioner and indoor unit 100 provided in this embodiment of the invention include:

[0091] In this embodiment, a movable sliding buckle 150 is provided on the decorative panel 130 to fix the decorative panel 130 to the middle frame 110, allowing the user to intuitively perceive that the decorative panel 130 is detachable. Furthermore, the decorative panel 130 is fixed to the middle frame 110 by the cooperation of hooks 131 and sliding buckles 150. During disassembly and assembly, simply moving the sliding buckle 150 is sufficient to release the fixation, making disassembly and installation more convenient. Compared to snap-fit ​​connections, this method is less prone to damage and offers higher installation stability.

[0092] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
