DETAILED DESCRIPTION

[0026] 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.

[0027] First embodiment

[0028] This embodiment provides an indoor unit 100. In the indoor unit 100 provided by this embodiment, the supporting portion 140 abuts against the middle frame 120, which can reduce the force applied to the movable portion 130 when the movable portion 130 is connected to the middle frame 120, thereby reducing the risk of damage to the movable portion 130 and improving the service life of the movable portion 130.

[0029] The indoor unit 100 is installed indoors and is used to exchange heat with indoor air. The indoor unit 100 includes a middle frame 120 and a panel 110. The panel 110 is installed on the outer surface of the indoor unit 100. The middle frame 120 is the main structure of the entire indoor unit 100 and is used to connect and secure other structures, such as the panel 110. To facilitate the removal of the panel 110, one side of the panel 110 is rotatably connected to the middle frame 120 via a hinge 130, while the other side is secured by a snap. When the panel 110 and the middle frame 120 are secured, one side of the panel 110 is connected to the middle frame 120 via the hinge 130, and the hinge 130 is subjected to significant pressure, which can easily lead to damage to the hinge 130. The indoor unit 100 provided in this embodiment can improve the above-mentioned problem. The panel 110 is provided with a supporting portion 140. The supporting portion 140 and the middle frame 120 contact each other to relieve the force on the hinge 130, thereby reducing the risk of damage to the hinge 130 and increasing the service life of the hinge 130.

[0030] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 In this embodiment, the indoor unit 100 includes a panel 110, a middle frame 120, a hinge portion 130 and a supporting portion 140. The hinge portion 130 is provided on the panel 110 and is movably connected to the middle frame 120. The supporting portion 140 is provided on the panel 110. When the panel 110 covers the middle frame 120, the supporting portion 140 is in contact with the middle frame 120.

[0031] In this embodiment, the supporting portion 140 and the movable leaf portion 130 are both arranged on the panel 110. When the panel 110 is covered on the middle frame 120, the movable leaf portion 130 is connected to the middle frame 120, and the supporting portion 140 is in contact with the middle frame 120, which can reduce the force on the movable leaf portion 130 when it is connected to the middle frame 120, thereby reducing the risk of damage to the movable leaf portion 130 and improving the service life of the movable leaf portion 130.

[0032] See also Figure 5 and Figure 6 In this embodiment, the hinge portion 130 has a first side surface 132 and a second side surface 134 that are oppositely disposed, and the supporting portion 140 is connected to the first side surface 132 .

[0033] That is to say, the supporting portion 140 is arranged close to the loose-leaf portion 130. Under the condition that the loose-leaf portion 130 is connected to the middle frame 120, the supporting portion 140 arranged close to the loose-leaf portion 130 abuts against the middle frame 120, which can alleviate the force on the loose-leaf portion 130 and transfer part or all of the force on the loose-leaf portion 130 to the supporting portion 140, so that the loose-leaf portion 130 only plays a connecting and positioning role as much as possible, thereby reducing the risk of damage to the loose-leaf portion 130 and improving the service life of the loose-leaf portion 130.

[0034] In this embodiment, the hinge portion 130 is generally plate-shaped, and one end of the hinge portion 130 away from the panel 110 is rotatably connected to the middle frame 120. When the panel 110 is placed on the middle frame 120, the connection between the hinge portion 130 and the middle frame 120 is subjected to a resisting force from the middle frame 120. The resisting portion 140 is connected to the first side surface 132 of the hinge portion 130. When the panel 110 is placed on the middle frame 120, the resisting portion 140 is first in contact with the middle frame 120, reducing the force applied to the hinge portion 130, thereby reducing the risk of damage to the hinge portion 130 and increasing the service life of the hinge portion 130.

[0035] See also Figure 7 In this embodiment, the indoor unit 100 further includes a reinforcing rib 150 , which is disposed on the second side surface 134 .

[0036] Since the supporting portion 140 is connected to the first side surface 132 of the movable leaf portion 130, when the supporting portion 140 is in contact with the middle frame 120, part of the force may be transferred to the plate-shaped movable leaf portion 130. In order to reduce the deformation of the movable leaf portion 130, a reinforcing rib 150 is provided on the second side surface 134 of the movable leaf portion 130 to increase the strength of the movable leaf portion 130, reduce the risk of deformation of the movable leaf portion 130, and improve the service life of the movable leaf portion 130.

[0037] In this embodiment, there are multiple reinforcing ribs 150, and the multiple reinforcing ribs 150 are staggered.

[0038] In order to improve the effect of the reinforcing ribs 150, a plurality of reinforcing ribs 150 are provided, and the plurality of reinforcing ribs 150 are staggered so that the plurality of reinforcing ribs 150 can enhance the strength of the movable-leaf portion 130 from different directions. Under the condition that the supporting portion 140 is in abutment with the middle frame 120, the reinforcing ribs 150 can increase the strength of the movable-leaf portion 130 and reduce the risk of deformation of the movable-leaf portion 130 due to the abutment of the supporting portion 140.

[0039] In this embodiment, when the reinforcing ribs 150 are provided, at least two reinforcing ribs 150 cross each other.

[0040] See also Figure 2 and Figure 4 In this embodiment, the supporting portion 140 has a supporting surface 142, and the middle frame 120 has a connecting surface 122. The connecting surface 122 is arranged toward the panel 110. When the panel 110 covers the middle frame 120, the supporting surface 142 and the connecting surface 122 resist each other.

[0041] In this embodiment, the abutting surface 142 and the connecting surface 122 abut against each other. Through the surface-to-surface contact, the force applied to the abutting portion 140 is made more uniform, reducing the possibility of damage to the panel 110 caused by localized force on the abutting portion 140. At the same time, the abutment between the connecting surface 122 and the abutting surface 142 increases the contact area between the abutting portion 140 and the middle frame 120, reducing the localized pressure on the panel 110 and thereby reducing the possibility of localized deformation of the panel 110.

[0042] In this embodiment, the shape of the abutting surface 142 matches the shape of the connecting surface 122 .

[0043] Among them, the shape of the supporting surface 142 is adapted to the shape of the connecting surface 122, so that the supporting surface 142 and the connecting surface 122 can be fully contacted when the supporting surface 142 and the connecting surface 122 are in abutment with each other, thereby increasing the contact area between the supporting surface 142 and the connecting surface 122, reducing the local pressure of the panel 110, and thus reducing the local deformation of the panel 110.

[0044] It is easy to understand that the shape of the abutting surface 142 is compatible with the shape of the connecting surface 122. This means that if the abutting surface 142 is flat, the connecting surface 122 is also flat. If the abutting surface 142 is convex, the connecting surface 122 is concave; conversely, if the abutting surface 142 is concave, the connecting surface 122 is convex. It is sufficient to ensure that the shape of the abutting surface 142 is compatible with the shape of the connecting surface 122.

[0045] In this embodiment, the panel 110 includes a panel body 112 and a bent portion 114 . The bent portion 114 is connected to one side of the panel body 112 . The hinge portion 130 and the abutting portion 140 are disposed on the bent portion 114 .

[0046] The panel body 112 is roughly in the shape of a long strip. In order to clearly describe the connection position between the bent portion 114 and the panel body 112 , the long side of the panel body 112 is positioned as the side and the wide side as the end, and the bent portion 114 is arranged on the long side of the panel body 112 .

[0047] Furthermore, the length of the panel body 112 is the same as the length of the bent portion 114 , that is, the entire panel 110 is also substantially in the shape of a long strip.

[0048] The supporting portion 140 and the movable portion 130 are both arranged at one end of the curved portion 114. When the movable portion 130 is connected to the middle frame 120, the movable portion 130 is easily subjected to a large tensile force. The supporting portion 140 is also arranged on the curved portion 114, which can enable the supporting portion 140 to abut against the middle frame 120, thereby alleviating the force on the movable portion 130.

[0049] In this embodiment, the cross-section of the curved portion 114 along its length is arc-shaped, and the first transition surface 144 connecting the supporting portion 140 to the curved portion 114 is also arc-shaped. To ensure that the entire curved portion 114 fits snugly against the curved portion 114, the supporting portion 140 also has an arc-shaped cross-section along its length, and the supporting portion 140 and the curved portion 114 are concentrically disposed.

[0050] The supporting portion 140 further has a second transition surface 146 . One end of the supporting surface 142 is connected to the first transition surface 144 , and the other end is connected to the second transition surface 146 . The first transition surface 144 is arc-shaped, that is, the first transition surface 144 and the second transition surface 146 are arranged opposite to each other.

[0051] Furthermore, the area of ​​the second transition surface 146 is smaller than that of the first transition surface 144. The area of ​​the second transition surface 146 is larger, which can increase the contact area between the supporting portion 140 and the bent portion 114. Under the condition that the supporting surface 142 and the connecting surface 122 of the middle frame 120 are in contact with each other, local force on the bent portion 114 can be avoided, resulting in deformation of the bent portion 114.

[0052] In this embodiment, there are two movable parts 130 , which are respectively arranged at both ends of the panel 110 . The indoor unit 100 further includes a connecting rib, which is arranged on the panel 110 and connected to the two movable parts 130 .

[0053] The two movable parts 130 are respectively arranged at the two ends of the bending part 114. The shapes and structures of the two movable parts 130 are the same. The first side surfaces 132 of the two movable parts 130 are arranged opposite to each other, that is, the first side surfaces 132 of the two movable parts 130 are both on the inner side and the second side surfaces 134 are both on the outer side.

[0054] Connecting ribs are provided on the curved portion 114, with both ends connected to the two hinge portions 130. Since the entire panel 110 is long and the curved portion 114 is relatively long, the connecting ribs can be used to strengthen the entire panel 110 in the longitudinal direction and reduce deformation of the panel 110 so that the central portion of the panel 110 does not deform when the panel 110 is placed on the middle frame 120.

[0055] In this embodiment, the abutting portion 140 is connected to one of the hinge portions 130 .

[0056] It should be noted that in this embodiment, there is only one abutting portion 140, which is disposed at one of the hinge portions 130. In other embodiments, two abutting portions 140 may be provided, with one abutting portion 140 disposed at each hinge portion 130. Solutions equivalent to this embodiment that can achieve the effects of this embodiment are within the scope of protection of the present invention.

[0057] The working principle of the indoor unit 100 provided in this embodiment is as follows: in this embodiment, the hinge portion 130 is rotatably connected to the middle frame 120, and when the panel 110 is covered on the middle frame 120, the supporting surface 142 of the supporting portion 140 is in contact with the connecting surface 122 of the middle frame 120.

[0058] To sum up, in the indoor unit 100 provided in this embodiment, in this embodiment, the supporting portion 140 and the movable portion 130 are both arranged on the panel 110. When the panel 110 is covered on the middle frame 120, the movable portion 130 is connected to the middle frame 120, and the supporting portion 140 is in contact with the middle frame 120, which can reduce the force applied to the movable portion 130 when the movable portion 130 is connected to the middle frame 120, thereby reducing the risk of damage to the movable portion 130 and improving the service life of the movable portion 130.

[0059] Second embodiment

[0060] This embodiment provides an air conditioner. In the air conditioner provided by this embodiment, the supporting portion 140 abuts against the middle frame 120, which can reduce the force applied to the loose-leaf portion 130 when the loose-leaf portion 130 is connected to the middle frame 120, thereby reducing the risk of damage to the loose-leaf portion 130 and increasing the service life of the loose-leaf portion 130.

[0061] For the sake of brief description, reference may be made to the first embodiment for matters not mentioned in this embodiment.

[0062] In this embodiment, the air conditioner includes the indoor unit 100 provided in the first embodiment.
