[0002] With the continuous improvement of people's living standards, air conditioners have been very widely used.

[0003] In order to make the appearance of the fresh air conditioner more beautiful, the shell of the indoor unit of the fresh air conditioner often needs to be decorated. Due to different decoration effects, different materials and processes need to be used for processing. Different materials and processes on an integrally formed piece not only are very troublesome, but also can affect each other. In order to avoid the mutual influence between different materials and processes, the decorative plate of the fresh air conditioner adopts a split design.

[0004] However, the decorative plate with a split design needs to be fixed relative to the fresh air base by screws during assembly, which is relatively troublesome. SUMMARY

[0005] The problem solved by the present application is that the decorative plate of the air conditioner with a split design needs to be fixed relative to the base by screws during assembly, which is relatively troublesome.

[0006] To solve the above problems, the embodiments of the present application provide a fresh air decorative plate assembly, an indoor unit and a fresh air conditioner, which can quickly install the decorative plate on the fresh air base.

[0007] In a first aspect, the present application provides a fresh air decorative plate assembly applied to an indoor unit of a fresh air conditioner, the fresh air decorative plate assembly comprising a fresh air base and a decorative plate; the fresh air base is configured as a base of the indoor unit, and the decorative plate is installed on the fresh air base through a buckle structure.

[0008] This embodiment can more conveniently assemble the decorative plate on the fresh air base during assembly by installing the decorative plate on the fresh air base through the buckle structure. At the same time, the use of fasteners can be avoided, which is more cost-saving.

[0009] In an optional embodiment, the buckle structure comprises a clamping hole provided on the fresh air base and a clamping hook provided on the decorative plate, and the clamping hook and the clamping hole cooperate to install the decorative plate on the fresh air base.

[0010] This embodiment can conveniently install the decorative plate on the fresh air base by cooperating the clamping hook provided on the decorative plate with the clamping hole provided on the fresh air base. At the same time, since the clamping hole is provided on the fresh air base, it will not affect the appearance of the decorative plate.

[0011] In an optional embodiment, the clamping hook comprises a connecting segment protruding from the decorative plate and a clamping segment provided on the connecting segment, the clamping segment protrudes from the side wall of the connecting segment, the decorative plate is installed on the outer wall of the fresh air base, the clamping hole is used for the clamping segment to pass through the fresh air base, and the clamping segment is movable along the protruding direction of the clamping segment to make the clamping segment abut against the inner wall of the fresh air base.

[0012] The clamping hook of the embodiment has a clamping segment provided on the connecting segment. When the decorative plate is assembled, the clamping segment of the clamping hook passes through the clamping hole provided on the fresh air base, and the decorative plate is moved relative to the fresh air base by pushing the decorative plate to make the clamping segment abut against the inner wall of the fresh air base, so that the decorative plate is quickly installed on the fresh air base, and the assembly efficiency is improved.

[0013] In an optional embodiment, the connecting segment abuts against the side wall of the clamping hole. In the embodiment, the movement of the decorative plate is limited by abutting the connecting segment against the side wall of the clamping hole, so that the installation of the decorative plate is more stable.

[0014] In an optional embodiment, the clamping hole comprises a first slot segment and a second slot segment in communication with each other, the first slot segment is used for the clamping segment to pass through the fresh air base, the width of the second slot segment is the same as the width of the connecting segment, the connecting segment is movable along the length direction of the second slot segment to make the clamping segment abut against the inner wall of the fresh air base and the connecting segment abut against the side wall of the second slot segment.

[0015] In the embodiment, the first slot segment is provided to facilitate the clamping segment of the clamping hook to pass through the fresh air base. The second slot segment is provided, and the width of the second slot segment is the same as the width of the connecting segment. Since the decorative plate moves along the protruding direction of the clamping segment, when the connecting segment is located in the second slot segment, the side wall in the width direction of the second slot segment abuts against the two faces in the width direction of the connecting segment, so that the movement of the decorative plate relative to the width direction of the second slot segment is limited. Meanwhile, when the decorative plate moves along the direction of the second slot segment, the end face of the connecting segment abuts against the end face of the second slot segment, so that the movement of the decorative plate in the direction of the second slot segment is limited. Through the above two direction limitations, the positioning of the decorative plate is realized, and the installation of the decorative plate is more stable.

[0016] In an optional embodiment, the inner wall of the fresh air base protrudes a limiting part, and the limiting part abuts against the side wall of the clamping segment.

[0017] In the embodiment, the limiting part is protruded from the inner wall of the fresh air base, and the limiting part and the clamping part abut against each other to limit the movement of the decorative plate in cooperation with the second slot segment.

[0018] In an optional embodiment, the fresh air base includes a first bottom wall and a first side wall connected to the first bottom wall; the decorative panel includes a second bottom wall and a second side wall connected to the second bottom wall; the first bottom wall abuts against the second bottom wall, and the first side wall abuts against the second side wall.

[0019] In an optional embodiment, there are multiple hooks and holes, and the hooks and holes correspond one-to-one; some hooks are disposed on the second bottom wall, and other hooks are disposed on the second side wall; some holes are disposed on the first bottom wall, and other holes are disposed on the first side wall.

[0020] In this embodiment, the first and second bottom walls abut against the inner wall of the fresh air base, thereby clamping the decorative panel to the fresh air base using hooks and restricting its movement. Multiple hooks and holes are provided to distribute the force more evenly. Furthermore, hooks are provided on the first side wall and hooks on the second side wall, with the clamping sections of the hooks abutting against the inner wall of the first side wall, thus restricting the movement of the decorative panel.

[0021] In an optional embodiment, the buckle structure further includes a first locking part disposed on the fresh air base and a second locking part disposed on the decorative panel, wherein the first locking part and the second locking part cooperate to fix the decorative panel to the fresh air base.

[0022] Because the decorative panel is fixed by the cooperation of hooks and holes, the decorative panel has a degree of freedom in the opposite direction of the direction of the hole extension, which makes the installation of the decorative panel unstable. In this embodiment, a first locking part is set on the fresh air base and a second locking part is set on the decorative panel. The decorative panel can be fixedly installed on the fresh air base by the cooperation of the first locking part and the second locking part, thereby making the installation of the decorative panel more stable.

[0023] In an optional embodiment, the first locking part protrudes from the inner wall of the fresh air base, and the first locking part includes a first locking surface and a first guide surface; the second locking part protrudes from the outer wall of the decorative panel, and the second locking part includes a second locking surface and a second guide surface; the first guide surface and the second guide surface are used to guide the second locking part when the decorative panel moves, so that the second locking part passes over the first locking part and the first locking surface and the second locking surface abut against each other.

[0024] In this embodiment, by providing a first guide surface on the first locking part and a second guide surface on the second locking part, the second locking part can better pass over the first locking part during the installation of the decorative panel, guided by the first and second guide surfaces. By providing a first locking surface and a second locking surface, when the second locking part passes over the first locking part, the first locking surface and the second locking surface cooperate to restrict the second locking part from passing over the first locking part, thereby fixing the decorative panel relative to the fresh air base.

[0025] In an optional embodiment, the fresh air base includes a first bottom wall and a first side wall connected to the first bottom wall; the decorative panel includes a second bottom wall and a second side wall connected to the second bottom wall; the first bottom wall abuts against the second bottom wall, and the first side wall abuts against the second side wall;

[0026] The first locking part is disposed on the outer wall of the first side wall; the second locking part is disposed on the inner wall of the second side wall, and the end face of the second locking part is flush with the end face of the second side wall.

[0027] In this embodiment, by setting the second locking part on the inner wall of the second side wall and making the end face of the second locking part flush with the end face of the second side wall, the second locking part can be seen to pass over the first locking part during the assembly of the decorative panel, so as to facilitate better installation of the decorative panel.

[0028] In an optional embodiment, the first sidewall and the second sidewall abut against each other, and the first sidewall and / or the outer wall are recessed with a relief groove, which is used to accommodate the first locking part and the second locking part.

[0029] In this embodiment, by recessing clearance grooves in the first sidewall and / or the second sidewall, the first and second locking parts can be kept out of contact with the decorative panel and the fresh air base during the installation of the decorative panel, making it easier to push the decorative panel more smoothly so that the second locking part can pass over the first locking part.

Detailed Implementation

[0042] To enhance the aesthetics of a fresh air conditioning unit, the outer casing of the indoor unit often needs to be decorated. Different decorative effects require different materials and processes. Applying different materials and processes to a single molded component is not only cumbersome but can also lead to interference between different materials and processes. To avoid these interfering effects, the decorative panels of the fresh air conditioning unit are designed as separate units.

[0043] However, the decorative panel with a split design needs to be fixed to the fresh air base with screws during assembly, which makes the assembly process rather complicated.

[0044] 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.

[0045] Please refer to Figure 1 This embodiment provides a fresh air air conditioner, which includes an indoor unit 300 and an outdoor unit (not shown), and the indoor unit 300 and the outdoor unit are connected by a pipe.

[0046] like Figure 2 As shown, in this embodiment, the indoor unit 300 includes a fresh air module 310 and a fresh air decorative panel assembly 100. The fresh air module 310 is installed on the fresh air decorative panel assembly 100.

[0047] Please refer to Figure 1 , Figure 2 and Figure 3 In this embodiment, the indoor unit 300 further includes an air conditioner base 330, a middle frame 350, and a panel 370. The fresh air decorative panel assembly 100 is fixedly connected to the air conditioner base 330. The middle frame 350 is installed on the fresh air decorative panel assembly 100 and the air conditioner base 330. The panel 370 is installed on the middle frame 350. An air outlet 371 is provided on the panel 370. The fresh air module 310 is installed within the space formed by the middle frame 350, the panel 370, and the fresh air decorative panel assembly 100, and the fresh air module 310 corresponds to the air outlet 371, so that the fresh air processed by the fresh air module 310 is discharged from the air outlet 371.

[0048] Please refer to Figure 4 In this embodiment, the fresh air decorative panel assembly 100 includes a fresh air base 110 and a decorative panel 130. The decorative panel 130 is installed on the fresh air base 110 via a snap-fit ​​structure 170.

[0049] By installing the decorative panel 130 onto the fresh air base 110 via the snap-fit ​​structure 170, the decorative panel 130 can be more easily assembled onto the fresh air base 110 during assembly. At the same time, the use of screws can be avoided, thus saving costs.

[0050] Please continue to refer to Figure 1 andFigure 2 In this embodiment, the fresh air base 110 is installed on the air conditioner base 330. The middle frame 350 is connected to the decorative panel 130 so that the decorative panel 130 is located at the corner of the transition between the middle frame 350 and the air conditioner base 330, thereby realizing the transition between the air conditioner base 330 and the middle frame 350 through the decorative panel 130.

[0051] Please continue to refer to Figure 4 In this embodiment, the snap-fit ​​structure 170 includes a snap hole 111 disposed on the fresh air base 110 and a snap hook 131 disposed on the decorative panel 130. The snap hook 131 cooperates with the snap hole 111 to install the decorative panel 130 onto the fresh air base 110.

[0052] In this embodiment, the decorative panel 130 can be easily installed on the fresh air base 110 by using the hook 131 provided on the decorative panel 130 and the locking hole 111 provided on the fresh air base 110. At the same time, since the locking hole 111 is provided on the fresh air base 110, it will not affect the appearance of the decorative panel 130.

[0053] Please refer to Figure 4 , Figure 5 and Figure 7 In this embodiment, the hook 131 includes a connecting section 133 protruding from the decorative panel 130 and a retaining section 135 disposed on the connecting section 133. The retaining section 135 extends out of the side wall of the connecting section 133. The decorative panel 130 is mounted on the outer wall of the fresh air base 110, and the inner wall of the decorative panel 130 abuts against the outer wall of the fresh air base 110. The locking hole 111 is used for the retaining section 135 to pass through the fresh air base 110. The decorative panel 130 can drive the retaining section 135 to move along the protruding direction of the retaining section 135, so that the retaining section 135 abuts against the inner wall of the fresh air base 110.

[0054] In this embodiment, the hook 131 has a retaining section 135 disposed on the connecting section 133. When assembling the decorative panel 130, the retaining section 135 of the hook 131 passes through the retaining hole 111 opened on the fresh air base 110. Then, by pushing the decorative panel 130, the decorative panel 130 moves relative to the fresh air base 110, causing the retaining section 135 to abut against the inner wall of the fresh air base 110. This allows the decorative panel 130 to be quickly installed on the fresh air base 110, improving assembly efficiency. At the same time, since the inner wall of the decorative panel 130 abuts against the outer wall of the fresh air base 110, and the retaining section 135 abuts against the inner wall of the fresh air base 110, the movement of the decorative panel 130 in the extending direction of the connecting section 133 is restricted.

[0055] Please refer to Figure 7 In this embodiment, the connecting segment 133 protrudes from the inner wall of the decorative panel 130. In other embodiments of this application, the connecting segment 133 may also protrude from the side wall of the decorative panel 130.

[0056] Please refer to Figure 4 and Figure 5 In this embodiment, the connecting segment 133 abuts against the side wall of the slot 111.

[0057] In this embodiment, by abutting the connecting section 133 against the side wall of the slot 111, the movement of the decorative panel 130 can be restricted, making the installation of the decorative panel 130 more stable.

[0058] Please continue to refer to Figure 4 and Figure 5 In this embodiment, the locking hole 111 includes a first groove segment 113 and a second groove segment 115 that are interconnected. The width of the first groove segment 113 is greater than the width of the retaining segment 135. The length of the first groove segment 113 is greater than the length of the retaining segment 135. The first groove segment 113 is used to retain the segment 135 as it passes through the fresh air base 110. The width of the second groove segment 115 is the same as the width of the connecting segment 133. The decorative plate 130 can drive the connecting segment 133 to move along the length direction of the second groove segment 115, so that the retaining segment 135 abuts against the inner wall of the fresh air base 110 and the connecting segment 133 abuts against the inner wall of the second groove segment 115.

[0059] In this embodiment, by setting the width of the first groove segment 113 to be greater than the width of the retaining segment 135 and the length of the first groove segment 113 to be greater than the length of the retaining segment 135, it is easier for the retaining segment 135 of the hook 131 to pass through the fresh air base 110. By setting the second groove segment 115, and making the width of the second groove segment 115 the same as the width of the connecting segment 133, the decorative panel 130 moves along the direction of the second groove segment 115 during assembly, so that the connecting segment 133 is located in the second groove segment 115. Since the width of the second groove segment 115 and the width of the connecting segment 133 are the same, when the connecting segment 133 is located in the second groove segment 115, the outer wall of the connecting segment 133 abuts against the inner wall of the second groove segment 115, thereby restricting the movement of the decorative panel 130 relative to the width direction of the second groove segment 115. Simultaneously, during the assembly of the decorative panel 130, the connecting section 133 moves away from the first groove section 113, causing the end face of the connecting section 133 to abut against the end face of the second groove section 115, thereby restricting the decorative panel 130 from moving further towards the second groove section 115. These three directional restrictions achieve the positioning of the decorative panel 130 and make its installation more stable.

[0060] In this embodiment, the connecting segment 133 has a rectangular cross-section, and the second groove segment 115 has a rectangular groove. After the decorative panel 130 is assembled, the two sidewalls of the connecting segment 133 in the width direction abut against the two sidewalls of the second groove segment 115 in the width direction. The sidewall of the connecting segment 133 near the end face of the second groove segment 115 in the length direction abuts against the end face of the second groove segment 115 in the length direction.

[0061] It should be noted that the width direction of the connecting segment 133 and the width direction of the second groove segment 115 are perpendicular to the extension directions of the first groove segment 113 and the second groove segment 115. The length direction of the connecting segment 133 and the length direction of the second groove segment 115 are parallel to the extension directions of the first groove segment 113 and the second groove segment 115.

[0062] Please continue to refer to Figure 4 and Figure 5 In this embodiment, since the widths of the first groove segment 113 and the second groove segment 115 are different, in order to make the connecting segment 133 move better from the first groove segment 113 to the second groove segment 115, a guide slope 117 is provided between the first groove segment 113 and the second groove segment 115. The guide slope 117 is connected to both the first groove segment 113 and the second groove segment 115, so that the connecting segment 133 can move better from the first groove segment 113 to the second groove segment 115 under the guidance of the guide slope 117.

[0063] In this embodiment, there is one guide ramp 117, which is disposed on the side wall of the first groove segment 113 and the second groove segment 115 located on the same side. The first groove segment 113 and the second groove segment 115 are located on the side wall of the other side with a straight transition.

[0064] In other embodiments of this application, the guide ramp 117 may also consist of two, with the two guide ramps 117 respectively connected to the sidewalls of the first groove segment 113 and the second groove segment 115 located on the same side.

[0065] Please refer to Figure 5 In this embodiment, the inner wall of the fresh air base 110 is provided with a limiting part 119. There are two limiting parts 119, which are respectively disposed on both sides of the width direction of the holding section 135, and the two side walls of the holding section 135 abut against the two limiting parts 119 respectively.

[0066] In this embodiment, a limiting part 119 is provided on the inner wall of the fresh air base 110. The limiting part 119 and the holding part abut against each other, which can cooperate with the second groove section 115 to restrict the movement of the decorative panel 130. The fixing of the decorative panel 130 is more stable.

[0067] In this embodiment, reinforcing ribs 137 are provided on the connecting section 133 and the retaining section 135 along the extending direction of the connecting section 133 and the retaining section 135. The reinforcing ribs 137 are used to enhance the load-bearing capacity of the hook 131.

[0068] In this embodiment, the end face of the retaining segment 135 and the side wall are transitioned by a chamfer, so that the retaining segment 135 can be better inserted between the two limiting parts 119.

[0069] Please refer to Figure 2 ,Figure 3 , Figure 4 and Figure 7 In this embodiment, the fresh air base 110 includes a first bottom wall 121 and a first side wall 123 connected to the first bottom wall 121. The decorative panel 130 includes a second bottom wall 139 and a second side wall 141 connected to the second bottom wall 139. The first bottom wall 121 abuts against the second bottom wall 139. The first side wall 123 abuts against the second side wall 141. Because the decorative panel 130 includes a second bottom wall 139 and a second side wall 141 connected to the second bottom wall 139, the air conditioner base 330 abuts against the second bottom wall 139, and the middle frame 350 abuts against the second side wall 141, thereby better achieving the transition between the air conditioner base 330 and the middle frame 350. At the same time, the decorative panel 130 achieves a wrapping effect on the air conditioner base 330 and the middle frame 350.

[0070] Please refer to Figure 2 and Figure 7 In this embodiment, to make the decorative panel 130 more aesthetically pleasing and present a curved surface effect, a curved transition section 143 is provided between the second side wall 141 and the second bottom wall 139. When the fresh air decorative panel 130 is installed on the indoor unit 300, the air conditioner base 330 covers the outside of the second bottom wall 139, and the middle frame 350 covers the outside of the second side wall 141, so that the air conditioner base 330, the transition section 143 and the middle frame 350 form a wrapping effect, making the indoor unit 300 more aesthetically pleasing.

[0071] Please continue to refer to Figure 4 In this embodiment, there are multiple hooks 131 and multiple holes 111, and each hook 131 and hole 111 corresponds to another. A portion of the hooks 131 are located on the second bottom wall 139, and another portion are located on the second side wall 141. A portion of the holes 111 are located on the first bottom wall 121, and another portion are located on the first side wall 123. When the decorative panel 130 is installed on the fresh air base 110, the hooks 131 located on the second side wall 141 pass through the holes 111 on the first side wall 123, causing the retaining sections 135 of these hooks 131 to abut against the inner wall of the first side wall 123; similarly, the hooks 131 located on the second bottom wall 139 pass through the holes 111 on the second bottom wall 139, causing the retaining sections 135 of these hooks 131 to abut against the inner wall of the second side wall 141. Multiple hooks 131 and locking holes 111 are provided so that the force can be distributed and the force can be more evenly distributed. Secondly, locking holes 111 are provided on the first side wall 123 and hooks 131 are provided on the second side wall 141 so that the locking section 135 of the hook 131 abuts against the inner wall of the first side wall 123, thereby restricting the movement of the decorative panel 130.

[0072] Please refer to Figure 4 and Figure 6Since the decorative panel 130 fixed in the above manner also has the degree of freedom to move in the direction of the first groove segment 113, in order to fix the decorative panel 130 to the fresh air base 110, in this embodiment, the buckle structure 170 further includes a first locking part 125 disposed on the fresh air base 110 and a second locking part 145 disposed on the decorative panel 130. The first locking part 125 and the second locking part 145 cooperate to fix the decorative panel 130 to the fresh air base 110.

[0073] In this embodiment, a first locking part 125 is provided on the fresh air base 110, and a second locking part 145 is provided on the decorative panel 130. By using the cooperation of the first locking part 125 and the second locking part 145, the decorative panel 130 can be fixedly installed on the fresh air base 110, thereby making the installation of the decorative panel 130 more stable.

[0074] Please continue to refer to Figure 4 and Figure 6 In this embodiment, the first locking portion 125 protrudes from the inner wall of the fresh air base 110. The first locking portion 125 includes a first locking surface 127 and a first guide surface 129. The second locking portion 145 protrudes from the outer wall of the decorative panel 130. The second locking portion 145 includes a second locking surface 147 and a second guide surface 149. The first guide surface 129 and the second guide surface 149 are used to guide the second locking portion 145 when the decorative panel 130 moves, so that the second locking portion 145 passes over the first locking portion 125 and the first locking surface 127 and the second locking surface 147 abut against each other.

[0075] In this embodiment, by providing a first guide surface 129 on the first locking part 125 and a second guide surface 149 on the second locking part 145, when the decorative panel 130 is installed, the first guide surface 129 and the second guide surface 149 guide the second locking part 145 to better pass over the first locking part 125, thereby causing the first locking surface 127 and the second locking surface 147 to abut against each other, restricting the second locking part 145 from passing over the first locking part 125, thereby fixing the decorative panel 130 relative to the fresh air base 110.

[0076] In this embodiment, the cross-section of the first locking part 125 is a right-angled trapezoid, with the plane containing the inclined waist of the right-angled trapezoid being the first guide surface 129, and the plane containing the vertical waist being the first locking surface 127. The cross-section of the second locking part 145 is also a right-angled trapezoid, with the plane containing the inclined waist of the right-angled trapezoid being the second guide surface 149, and the plane containing the vertical waist being the second locking surface 147.
