Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning structures, and in particular to an air conditioning indoor unit and an air conditioner. Background Art

[0002] To shorten the length of an air conditioner indoor unit, a pivot hole is currently provided on the end cover to mate with the panel's pivot. A slot for accommodating the panel's hinge is formed between the end cover and the middle frame. To ensure easy installation of the hinge, the slot has a large gap. When the panel is opened, the hinge can easily deform under the weight of the panel, even detaching from the retaining structure and causing the panel to close. Summary of the Invention

[0003] The problem solved by the present invention is how to prevent the panel from sliding down or even closing when the panel is in the open state.

[0004] In order to solve the above problems, the present invention provides an air conditioner indoor unit and an air conditioner, which can effectively improve the above-mentioned technical problems.

[0005] The present invention can be implemented like this:

[0006] An embodiment of the present invention provides an air conditioner indoor unit, which includes a middle frame; an end cover, which is installed at the end of the middle frame, and an installation space is defined between the end cover and the middle frame; and a panel, the hinge of the panel is installed in the installation space; wherein, the middle frame is provided with a spring buckle located in the installation space, and the hinge is provided with an abutment protrusion, and the abutment protrusion is used to abut with the spring buckle to put the panel in an open state; the end cover is provided with a limiting protrusion located in the installation space, the spring buckle and the limiting protrusion are distributed along the length direction of the middle frame, and the limiting protrusion and the spring buckle are used to respectively abut on both sides of the hinge when the panel is in the open state.

[0007] By setting a limiting protrusion on the end cover and distributing it along the length direction of the middle frame with the spring buckle, when the panel is in the open state, the stability of the hinge can be effectively guaranteed by the support of the limiting protrusion and the spring buckle on both sides of the hinge, avoiding the deformation of the hinge and the problem of closing the panel.

[0008] Optionally, the limiting protrusion includes a plurality of first ribs and a plurality of second ribs, the plurality of first ribs are arranged side by side, the plurality of second ribs are arranged side by side, and the plurality of first ribs and the plurality of second ribs are arranged in an alternating manner.

[0009] By simplifying the limiting protrusion into a structure formed by staggered multiple ribs, the volume of the limiting protrusion is reduced, which helps to reduce the obstruction of the limiting protrusion to the hinge when the panel is installed, thereby facilitating the panel installation.

[0010] Optionally, the first rib is arc-shaped, and the center of the arc is located on the rotation axis of the movable leaf.

[0011] Since the first rib is an arc arranged around the rotation axis of the panel, the sliding friction between the hinge and the first rib can be reduced during the installation and even rotation of the panel, ensuring the smooth rotation of the hinge to achieve opening and closing operations.

[0012] Optionally, the first rib is in a straight line shape, and when the panel is in the open state, the radial line where the abutting protrusion is located is perpendicular to the first rib.

[0013] By setting the first rib to be a straight line perpendicular to the radial line where the abutting protrusion is located in the open state, the first rib extends along the installation direction of the panel when the panel is installed, thereby reducing the sliding friction between the hinge and the first rib during the installation process.

[0014] Optionally, a protruding height of the second rib is lower than a protruding height of the first rib.

[0015] The height of the second rib is lower than the protruding height of the first rib. In this way, when the panel slides relative to the end cover along the installation direction, the second rib produces less resistance to the hinge. Correspondingly, when the panel is disassembled, the force exerted by the second rib on the hinge to hinder the sliding of the hinge is also smaller, thereby facilitating the disassembly and assembly of the panel and reducing the impact of the limiting protrusion on the disassembly and assembly of the panel.

[0016] Optionally, a shaft hole is provided on the end cover, and the shaft of the hinge rotates in conjunction with the shaft hole.

[0017] The end caps are equipped with pivot holes, allowing the hinged hinge on the hinge to rotate with the hinge hole to rotate the panel relative to the middle frame, thereby opening and closing the panel. Furthermore, by placing the hinge holes on the end caps, there's no need to reserve a location for the pivot holes in the middle frame, further shortening the air conditioner's indoor unit and meeting indoor layout requirements.

[0018] Optionally, the shaft hole includes a mounting end and a rotating end that are connected to each other, an opening area of ​​the mounting end is larger than an opening area of ​​the rotating end, and the rotating end is arranged close to the limiting protrusion relative to the mounting end.

[0019] By designing the hinge hole with a connecting mounting end and a rotating end, with the mounting end opening area larger than the rotating end, the hinge on the hinged hinge is installed from the mounting end into the hinge hole during panel installation, facilitating hinge installation. After installation, the hinge slides from the mounting end to the rotating end, and the panel opens and closes through the rotational coordination of the rotating end and the hinge. Furthermore, the smaller opening area at the rotating end effectively limits the hinge's rotation, ensuring reliable panel rotation.

[0020] Optionally, a groove is provided at the end of the middle frame, the installation space is defined between the bottom of the groove and the end cover, and the spring buckle is provided at the bottom of the groove.

[0021] The groove on the middle frame forms an installation space, which has a larger installation space and is conducive to the installation of the panel. At the same time, the thickness of the end cover does not need to be adjusted, which helps to ensure that the overall length of the air conditioner indoor unit is not significantly increased.

[0022] Optionally, a convex edge is provided on the end edge of the middle frame, the convex edge abuts against the end cover for limiting position, and the convex edge has a notch corresponding to the groove, and the notch is used for the loose-leaf hinge to enter and exit the installation space.

[0023] A convex edge is set on the periphery of the end of the middle frame, and the periphery of the end cover is in abutment with the convex edge for limiting position. In this way, a notch connected to the installation space is set on the convex edge, so that the panel hinge can be moved in and out of the installation space. The structure is simple and convenient for the processing, production and installation of parts.

[0024] An embodiment of the present invention further provides an air conditioner, comprising an indoor unit. The indoor unit comprises a middle frame; an end cover mounted at an end of the middle frame, defining an installation space between the end cover and the middle frame; and a panel, wherein a hinge of the panel is mounted within the installation space. The middle frame is provided with a snap fastener positioned within the installation space, and the end cover is provided with a limiting protrusion positioned within the installation space. The snap fasteners and limiting protrusions are distributed along the length of the middle frame, and the limiting protrusions and snap fasteners are configured to abut against both sides of the hinge when the panel is in an open state.

[0025] Since the air conditioner includes the above-mentioned air conditioner indoor unit, it also has the beneficial effect of improving the stability of the hinge, avoiding the problem of hinge deformation and thus causing the panel to close. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] 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.

[0036] Figure 1 This is a structural diagram of the air conditioner indoor unit 100 provided in this embodiment. Figure 2 This is a partial structural diagram of the air conditioner indoor unit 100 provided in this embodiment when the panel 130 is in the open state. Figure 3 This is a partial structural diagram of the installation of the panel 130 of the air conditioner indoor unit 100 provided in this embodiment. Figure 1-Figure 3 , this embodiment provides an air conditioner indoor unit 100, and accordingly, provides an air conditioner (not shown).

[0037] The air conditioner provided in this embodiment includes an air conditioner indoor unit 100, and the air conditioner also includes an air conditioner outdoor unit. The air conditioner outdoor unit and the air conditioner indoor unit 100 are connected by a pipeline, thereby forming a circulation channel for the flow of heat exchange medium. The heat exchange medium circulates between the air conditioner indoor unit 100 and the air conditioner outdoor unit, thereby realizing heat exchange between the air at the air conditioner indoor unit 100 and the air at the air conditioner outdoor unit, thereby realizing heating or cooling regulation of the indoor air.

[0038] The air conditioner indoor unit 100 includes a middle frame 110, an end cover 120, and a panel 130. The end cover 120 is mounted at the end of the middle frame 110, and an installation space 140 is defined between the end cover 120 and the middle frame 110. The hinge 132 of the panel 130 is installed in the installation space 140. At the same time, the middle frame 110 is provided with a spring buckle 113 located in the installation space 140, and the hinge 132 is provided with a contact protrusion 126. The panel 130 is in an open state through the contact between the contact protrusion 126 and the spring buckle 113; the end cover 120 is provided with a limiting protrusion 126 located in the installation space 140, and the limiting protrusion 126 and the spring buckle 113 are distributed along the length direction of the middle frame 110. In this way, when the panel 130 is in the open state, the spring buckle 113 and the limiting protrusion 126 are abutted on both sides of the hinge 132, thereby improving the stability of the hinge 132 and avoiding the closure of the panel 130 due to deformation of the hinge 132.

[0039] The air conditioner indoor unit 100 provided in this embodiment is further described below:

[0040] Figure 4 This is a structural diagram of the middle frame 110 in the air conditioner indoor unit 100 provided in this embodiment. Figures 1-4 In this embodiment, the end cover 120 is fastened to the middle frame 110 in the length direction ( Figure 1 and Figure 4 The panel 130 has a plate body 131 and hinges 132 at both ends of the plate body 131 (shown in the AB direction). The panel 130 is opened and closed by rotating the entire panel 130. When the panel 130 is closed, the plate body 131 covers the front side of the middle frame 110. When the panel 130 is open, the plate body 131 is tilted upward at a certain angle relative to the front side of the middle frame 110, thereby opening the front side of the middle frame 110, thereby facilitating cleaning operations such as the interior of the air conditioner indoor unit 100 from the front side of the middle frame 110.

[0041] An installation space 140 is defined between the end cap 120 and the end of the middle frame 110. A hinge 132 is rotatably mounted within this installation space 140. Rotation of the hinge 132 drives the plate 131 to rotate relative to the middle frame 110, thereby opening and closing the panel 130. Furthermore, a spring catch 113 is provided at the end of the middle frame 110. The hinge 132 is provided with an abutting protrusion 133 for contacting the spring catch 113. The abutment of the abutting protrusion 133 with the spring catch 113 maintains the panel 130 in an open position.

[0042] The end cover 120 is also provided with a limiting protrusion 126 located in the installation space 140, and the limiting protrusion 126 and the spring buckle 113 are distributed along the length direction of the middle frame 110, that is, in the length direction of the middle frame 110, the limiting protrusion 126 and the spring buckle 113 are arranged opposite to each other, so that when the panel 130 is in the open state, the limiting protrusion 126 and the side of the hinge 132 away from the spring buckle 113 are abutted, and then the limiting of the hinge 132 is achieved through the joint action of the limiting protrusion 126 and the spring buckle 113, thereby avoiding the deformation of the hinge 132 when the panel 130 is in the open state, and then the abutting protrusion 133 on the hinge 132 is separated from the spring buckle 113, resulting in the problem of closing the panel 130, thereby ensuring the stability of the panel 130 in the open state.

[0043] Furthermore, the cross section of the spring buckle 113 is triangular, and it has two inclined surfaces arranged at the top and bottom. Correspondingly, the cross section of the abutting protrusion 133 is also triangular, and the upper and lower side walls of the abutting protrusion 133 are also inclined surfaces. When the panel 130 is flipped upward, the upper inclined surface of the abutting protrusion 133 abuts against the lower inclined surface of the spring buckle 113, and pushes the spring buckle 113 to retract, so that the abutting protrusion 133 moves over the spring buckle 113 to the top of the spring buckle 113. At this time, the upper inclined surface of the spring buckle 113 and the lower inclined surface of the abutting protrusion 133 are in contact and limited, so that the panel 130 is in the open state (as shown in FIG. Figure 2 At the same time, the limiting protrusion 126 abuts against the side of the hinge 132 facing away from the snap 113. The combined action of the snap 113 and the limiting protrusion 126 prevents deformation of the hinge 132, which could otherwise cause the abutting protrusion 133 to separate from the snap 113 without external force. Similarly, to close the panel 130, a downward force is applied to the panel 130, increasing the resistance force on the snap 113 and causing it to retract, allowing the abutting protrusion 133 to move from the upper side of the snap 113, past the snap 113, to the lower side of the snap 113.

[0044] Furthermore, a groove 112 is provided at the end of the middle frame 110. The bottom of the groove 112 and the end cover 120 define an installation space 140, and a spring latch 113 is provided on the bottom of the groove. Specifically, the front portion of the upper middle portion of the end surface of the middle frame 110 is recessed inward along the length of the middle frame 110 to form the groove 112. In this way, when the end cover 120 is fastened to the end of the middle frame 110, the bottom of the groove 112 (i.e., the wall surface of the groove 112 at the end of the middle frame 110 away from the end cover 120 along the length of the middle frame 110) and the space between the end surface of the end cover 120 closer to the middle frame 110 constitutes the installation space 140.

[0045] Figure 5 This is a structural diagram of the notch 114 in the air conditioner indoor unit 100 provided in this embodiment. Figure 1-Figure 5 Furthermore, a flange 111 is provided on the periphery of the end portion. The flange 111 protrudes along the length of the middle frame 110 and abuts against the end cap 120 to limit the position. This ensures a tight fit between the middle frame 110 and the end cap 120, while also increasing the size of the installation space 140 and facilitating the assembly and disassembly of the hinge 132. The flange 111 also has a notch 114 corresponding to the groove 112, through which the hinge 132 can enter and exit the installation space 140, thereby achieving assembly and disassembly of the hinge 132.

[0046] Figure 6 This is a structural diagram of the end cover 120 of the air conditioner indoor unit 100 provided in this embodiment. Figure 7 for Figure 6 The enlarged diagram of the local structure at VII in the middle. Please refer to Figure 1-Figure 7 In this embodiment, a shaft hole 123 is provided on the end cover 120. This shaft hole 123 is designed to rotatably engage with the shaft on the hinge 132, thereby enabling rotation of the panel 130 relative to the middle frame 110. Because the shaft hole 123 is provided on the end cover 120, the space for the shaft installation can utilize the thickness of the end cover 120 itself, eliminating the need to reserve space on the middle frame 110. This helps further shorten the overall length of the air conditioner indoor unit 100.

[0047] Specifically, the end cap 120 includes a decorative strip 121 and a decorative cover 122. The shaft hole 123 is a through-hole provided in the decorative cover 122. The opening of the through-hole on the end away from the middle frame 110 is sealed by the decorative cover 122, thereby maintaining the overall appearance of the air conditioner indoor unit 100. Specifically, the decorative strip 121 is located on the side of the decorative cover 122 that is closest to the middle frame 110. Accordingly, the stopper protrusion 126 of the end cap 120 is provided on the decorative strip 121.

[0048] Furthermore, the shaft hole 123 includes a mounting end 124 and a rotating end 125 that are interconnected, and the opening area of ​​the mounting end 124 is larger than the opening area of ​​the rotating end 125. At the same time, the rotating end 125 is arranged closer to the limiting protrusion 126 relative to the mounting end 124, that is, the rotating end 125 is located in front of the mounting end 124. Specifically, during the installation process, the shaft is inserted into the mounting end 124. Since the opening area of ​​the mounting end 124 is larger, the installation of the shaft is facilitated. After installation, the shaft slides forward relative to the end cover 120 to the rotating end 125. In this way, when the panel 130 is opened and closed, the shaft rotates within the rotating end 125. Since the opening area of ​​the rotating end 125 is smaller, the movement of the shaft can be effectively limited, ensuring rotational stability.

[0049] Please continue to refer to Figure 1-Figure 7 In this embodiment, the limiting protrusion 126 includes a plurality of first ribs 127 and a plurality of second ribs 128. The plurality of first ribs 127 are arranged side by side, the plurality of second ribs 128 are arranged side by side, and the plurality of first ribs 127 and the plurality of second ribs 128 are arranged in an alternating manner. The limiting protrusion 126 formed in this way has a mesh structure.

[0050] Furthermore, the first rib 127 is a linear protrusion extending generally downward. When the panel 130 is in the open position, the radial line along which the abutment protrusion 133 lies is perpendicular to the first rib 127. In other words, the first rib 127 can be considered a tangent to the rotational trajectory of the hinge 132. This effectively reduces the frictional force exerted by the first rib 127 on the hinge 132, ensuring smooth opening and closing of the panel 130. It should be noted that the radial line along which the abutment protrusion 133 lies is the radial line connecting the abutment protrusion 133 and the rotational axis of the panel 130.

[0051] At the same time, the extension direction of the first rib 127 is the installation direction of the panel 130. In this way, during the disassembly and assembly process, the hinge 132 slides relative to the middle frame 110 along the extension direction of the first rib 127, that is, the limiting protrusion 126 has a multi-strip structure in the installation direction of the hinge 132, which helps to reduce the obstruction of the limiting protrusion 126 on the hinge 132 during the disassembly and assembly process, thereby facilitating the disassembly and assembly of the hinge 132.

[0052] It should be noted that the structure of the first rib 127 is not limited here. It can be understood that in other embodiments, the first rib 127 can also be set as needed. For example, the first rib 127 can be set to an arc shape, and the center of the arc is located on the rotation axis of the panel 130. In other words, the first rib 127 is set along the rotation trajectory of the panel 130, which can reduce the sliding friction generated by the limiting protrusion 126 during the rotation of the panel 130.

[0053] Furthermore, the raised height of the second rib 128 is lower than that of the first rib 127. That is, along the length of the middle frame 110, the distance between the second rib 128 and the middle frame 110 is greater than the distance between the first rib 127 and the middle frame 110. This reduces the impact of the second rib 128 on the assembly and disassembly of the hinges 132. Optionally, in this embodiment, the second rib 128 extends perpendicular to the first rib 127, meaning that the grid formed by the second rib 128 and the first rib 127 is square.

[0054] The air conditioner indoor unit 100 and the air conditioner provided by the embodiments of the present invention have a limiting protrusion 126 disposed on the end cover 120, which is opposite to the spring catch 113. Thus, when the panel 130 is in the open state, the spring catch 113 and the limiting protrusion 126 mutually interfere with the hinge 132, thereby improving the reliability of the hinge 132 and avoiding the problem of deformation of the hinge 132 causing the contact protrusion 133 of the hinge 132 to separate from the spring catch 113, thereby closing the panel 130. Furthermore, by further configuring the structure of the limiting protrusion 126, the effect of the additional limiting protrusion 126 on the assembly and disassembly process of the panel 130 is reduced, ensuring a smooth assembly and disassembly process of the panel 130 and reducing the sliding friction generated on the panel 130 during the opening and closing process.

[0055] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the scope defined by the claims.
