Description

Technical Field

[0001] This utility model relates to the field of air conditioning, and in particular to an air conditioner. Background Technology

[0002] The air inlet of an air conditioner is located at the rear of the unit. When the air conditioner is placed near curtains, such as in a corner or near a window, the suction effect of the inlet can easily cause the curtains to block the air inlet, reducing the air conditioning's air intake efficiency. In related technologies, curtain brackets are usually installed near the air inlet to separate the curtains from the air intake. However, the connection between the curtain brackets and the unit casing in these technologies is not secure enough, and the curtain brackets are prone to detaching and falling off, rendering the curtain brackets ineffective in blocking the airflow. Therefore, improvements are needed. Utility Model Content

[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0021] The following is for reference. Figures 1-7 This invention describes an air conditioner 100 according to an embodiment of the present invention.

[0022] An air conditioner 100 according to an embodiment of the present utility model includes: a housing 1, a curtain bracket 2, and a heat exchange and air supply assembly.

[0023] The housing 1 has an air inlet 120 and an air outlet 113. The air inlet 120 is located at the rear of the housing 1. A first connecting structure 13 is provided on the rear side of the housing 1. The first connecting structure 13 includes a first snap-fit ​​structure 131 and a limiting rib 135. The limiting rib 135 is located on the outer periphery of the first snap-fit ​​structure 131. A curtain bracket 2 is connected to the rear side of the housing 1 and protrudes rearward from the outer surface of the housing 1. The curtain bracket 2 has a second connecting structure 22. The second connecting structure 22 includes a second snap-fit ​​structure 221 and a limiting notch 224. The limiting notch 224 is located on the outer periphery of the second snap-fit ​​structure 221. The second snap-fit ​​structure 221 engages with the first snap-fit ​​structure 131. The limiting rib 135 is accommodated in the limiting notch 224. A heat exchange and air supply assembly is located inside the housing 1.

[0024] For example, a heat exchange air supply assembly may include heat exchanger components and fan components.

[0025] For example, when installing the curtain bracket 2 onto the housing 1, first place the curtain bracket 2 on the rear side of the housing 1, align the first snap-fit ​​structure 131 and the second snap-fit ​​structure 221 in the front-back direction, align the limiting rib 135 and the limiting notch 224 in the front-back direction, and then move the curtain bracket 2 forward so that the second snap-fit ​​structure 221 snaps into the first snap-fit ​​structure 131, and the limiting rib 135 is accommodated in the limiting notch 224.

[0026] By engaging the first snap-fit ​​structure 131 and the second snap-fit ​​structure 221, the curtain bracket 2 can be fixed to the housing 1 via snap-fit ​​connection.

[0027] By having the limiting rib 135 accommodated in the limiting notch 224, and the limiting rib 135 abutting against the inner peripheral wall of the limiting notch 224, the twisting or movement of the curtain bracket 2 relative to the housing 1 can be reduced, making the housing 1 more fully limiting the curtain bracket 2 and more fully preventing the curtain bracket 2 from falling off the housing 1.

[0028] In related technologies, the curtain bracket 2 is directly fixed to the housing 1 via a snap-fit ​​structure. The housing 1 does not adequately limit the curtain bracket 2, allowing it to slide and shift relative to the housing 1, potentially changing its position. The curtain bracket 2 is also more prone to rotation relative to the housing 1, leading to damage to the snap-fit ​​structure and detachment. By incorporating a first connecting structure 13 (including a first snap-fit ​​structure 131 and a limiting rib 135) and a second connecting structure 22 (including a second snap-fit ​​structure 221 and a limiting notch 224), and by ensuring that the first snap-fit ​​structure 131 and the second snap-fit ​​structure 221 are connected via snap-fit ​​while the limiting rib 135 is accommodated within the limiting notch 224, the two limiting methods provide a more secure connection between the curtain bracket 2 and the housing 1. Compared to the single connection method using only a snap-fit ​​structure in related technologies, this reduces the twisting or shifting of the curtain bracket 2 relative to the housing 1, effectively preventing it from detaching and falling off.

[0029] According to an embodiment of the present invention, the air conditioner 100 includes a curtain bracket 2 connected to the rear side of the housing 1. By including a first connecting structure 13 on the rear side of the housing 1, the first connecting structure 13 includes a first snap-fit ​​structure 131 and a limiting rib 135. The curtain bracket 2 is provided with a second connecting structure 22, the second connecting structure 22 includes a second snap-fit ​​structure 221 and a limiting notch 224. The first snap-fit ​​structure 131 and the second snap-fit ​​structure 221 can be connected by snap-fit, so that the curtain bracket 2 is fixed to the housing 1 by snap-fit. Furthermore, by accommodating the limiting rib 135 in the limiting notch 224, the housing 1 can more fully limit the curtain bracket 2, reduce the twisting or movement of the curtain bracket 2 relative to the housing 1, and more effectively prevent the curtain bracket 2 from falling off the housing 1.

[0030] According to some embodiments of the present invention, the first connecting structure 13 includes two limiting ribs 135, which are located on opposite sides of the first snap-fit ​​structure 131. The second connecting structure 22 includes two limiting notches 224, which are located on opposite sides of the second snap-fit ​​structure 221. The two limiting ribs 135 are respectively accommodated in the two limiting notches 224.

[0031] By including two limiting ribs 135 in the first connecting structure 13 and two limiting notches 224 in the second connecting structure 22, the two limiting ribs 135 can be respectively accommodated within the two limiting notches 224, making the limiting of the curtain bracket 2 by the housing 1 more sufficient, reducing the twisting or shifting of the curtain bracket 2 relative to the housing 1, and more effectively preventing the curtain bracket 2 from falling off the housing 1. By placing the two limiting notches 224 on opposite sides of the second snap-fit ​​structure 221, the curtain bracket 2 can be limited and fixed in two different positions, making the limiting of the curtain bracket 2 by the housing 1 more sufficient, and preventing the curtain bracket 2 from rotating relative to the housing 1, thus preventing the curtain bracket 2 from falling off the housing 1.

[0032] According to some embodiments of the present invention, the first snap-fit ​​structure 131 includes a first snap hole 132 and two first snap fasteners 133 spaced apart and oppositely arranged. The first snap fasteners 133 protrude from the inner peripheral wall of the first snap hole 132 toward the central axis of the first snap hole 132. The second snap-fit ​​structure 221 includes two snap-fit ​​plates 222 spaced apart and oppositely arranged. The snap-fit ​​plates 222 have second snap holes 223 formed on them. At least a portion of the two snap-fit ​​plates 222 is accommodated in the first snap hole 132, and the two first snap fasteners 133 are respectively snapped into the second snap holes 223 of the two snap-fit ​​plates 222.

[0033] For example, two first latches 133 are spaced apart along a first direction, and a first latch hole 132 is defined between the two first latches 133. The first direction can be a left-right direction.

[0034] For example, the central axis of the first slot 132 extends in the front-to-back direction, and the first buckle 133 protrudes rearward from the inner peripheral wall of the first slot 132.

[0035] By making the first snap-fit ​​structure 131 include two first snaps 133 that are spaced apart and opposite to each other, and the second snap-fit ​​structure 221 include two snap-fit ​​plates 222 that are spaced apart and opposite to each other, and by forming a second snap hole 223 on the snap-fit ​​plate 222, the two first snaps 133 can be snapped into the second snap hole 223 respectively, so that the curtain bracket 2 is fixed to the housing 1 by snap-fit ​​connection. The housing 1 provides more sufficient restriction on the curtain bracket 2, preventing the curtain bracket 2 from falling off the housing 1.

[0036] By making the first buckle 133 protrude from the inner peripheral wall of the first latch 132 toward the central axis of the first latch 132, the distance between the first buckle 133 and the bottom wall of the first latch 132 in the direction of the central axis of the first latch 132 can be longer. When the curtain bracket 2 tends to fall off relative to the housing 1, the latch plate 222 needs to move a longer distance to make the curtain bracket 2 fall off the housing 1, which can make the housing 1 more fully limit the curtain bracket 2.

[0037] According to some embodiments of the present invention, a guide surface 134 is formed on the rear surface of the first buckle 133, and the guide surface 134 extends forward at an angle in the direction from the central axis of the first buckle 133 to the first buckle hole 132.

[0038] For example, the first buckles 133 are spaced apart in the left and right directions, and the first buckles 133 define the first buckle hole 132 between the two first buckles 133. The rear surface of the first buckle 133 on the left side is formed with a guide surface 134, which extends forward at an angle in the direction from left to right. The rear surface of the first buckle 133 on the right side is also formed with a guide surface 134, which extends forward at an angle in the direction from right to left.

[0039] When installing the curtain bracket 2 onto the housing 1, first align the first snap-fit ​​structure 131 and the second snap-fit ​​structure 221 in the front-back direction, align the limiting rib 135 and the limiting notch 224 in the front-back direction, then move the curtain bracket 2 forward, so that the front side of the snap-fit ​​plate 222 abuts against the guide surface 134. Continue moving the curtain bracket 2, and the snap-fit ​​plate 222 moves forward. Under the guidance of the guide surface 134, the snap-fit ​​plate 222 bends and deforms towards the central axis of the first snap hole 132. Continue moving the curtain bracket 2 until the first buckle 133 is engaged in the second snap hole 223. At this time, the snap-fit ​​plate 222 springs open away from the central axis of the first snap hole 132, and the curtain bracket 2 is installed on the housing 1.

[0040] By making the guide surface 134 extend forward at an angle in the direction of the central axis from the first buckle 133 to the first hole 132, the guide surface 134 can play a role in guiding the installation of the snap plate 222, reducing the difficulty of installing the curtain bracket 2.

[0041] According to some embodiments of the present invention, the second connecting structure 22 includes a limiting protrusion 225, which is disposed on the opposite side of the two snap-fit ​​plates 222. The two snap-fit ​​plates 222 of the second snap-fit ​​structure 221 are arranged along a first direction, and each snap-fit ​​plate 222 is provided with two limiting protrusions 225 spaced apart along a second direction. A limiting notch 224 is defined between the two limiting protrusions 225 on each snap-fit ​​plate 222. One of the first direction and the second direction is a left-right direction and the other is a up-down direction. The first connecting structure 13 includes two limiting ribs 135, which are located on opposite sides of the first snap-fit ​​structure 131 along the first direction. The two limiting ribs 135 are respectively accommodated in the two limiting notches 224.

[0042] For example, the first direction can be left or right, and the second direction can be up or down.

[0043] For example, each limiting protrusion 225 abuts against the limiting rib 135 in the second direction.

[0044] By having the two limiting ribs 135 respectively accommodated in the two limiting notches 224, and the limiting ribs 135 abutting against the inner peripheral wall of the limiting notches 224, the housing 1 can more fully limit the curtain bracket 2, preventing the curtain bracket 2 from falling off the housing 1.

[0045] By including two limiting ribs 135 in the first connecting structure 13 and positioning the two limiting ribs 135 on opposite sides of the first snap-fit ​​structure 131 along the first direction, and having the two limiting ribs 135 respectively cooperate with the limiting notch 224 at two different positions on the housing 1, the housing 1 can more fully limit the curtain bracket 2, and can more fully prevent the curtain bracket 2 from rotating or moving relative to the housing 1, thus preventing the curtain bracket 2 from falling off relative to the housing 1.

[0046] According to some embodiments of this utility model, in the first direction, the limiting rib 135 located on the same side is integrally connected with the first buckle 133. For example, the limiting rib 135 located on the same side and the first buckle 133 are integrally formed. By making the limiting rib 135 located on the same side integrally connected with the first buckle 133 in the first direction, the limiting rib 135 can also fix and position the first buckle 133, preventing the first buckle 133 from moving relative to the housing 1 and causing the buckle connection between the first buckle 133 and the second buckle hole 223 to fail; and, there is no need to design a separate fixing device for the first buckle 133, making the first connecting structure 13 more compact and reducing the space occupied by the first connecting structure 13.

[0047] According to some embodiments of this utility model, the rear side of the housing 1 is provided with a positioning groove 123 with the opening facing rearward. The bottom wall 1231 of the positioning groove 123 is arranged opposite to the opening of the positioning groove 123. The bottom wall 1231 is provided with a first locking hole 132. A limiting rib 135 and a first buckle 133 are both provided on the bottom wall 1231. The limiting rib 135 protrudes rearward from the bottom wall 1231. The limiting rib 135 extends along a second direction. The positioning groove 123 includes two first side walls 1232 arranged opposite to each other along the second direction. Both ends of the limiting rib 135 along the second direction are spaced apart from the first side walls 1232 to form a limiting groove 1233. The limiting protrusion 225 is accommodated in the limiting groove 1233.

[0048] By providing a positioning groove 123 with an opening facing rearward on the rear side of the housing 1, and by setting the limiting rib 135 and the first buckle 133 on the bottom wall 1231 of the groove, it is easier for relevant personnel to find the position of the first connecting structure 13 when installing the curtain bracket 2 on the housing 1, and the difficulty for relevant personnel to pre-align the second connecting structure 22 with the first connecting structure 13 is reduced.

[0049] By making both ends of the limiting rib 135 along the second direction spaced apart from the first sidewall 1232 to form a limiting groove 1233, and the limiting protrusion 225 accommodated in the limiting groove 1233, the limiting groove 1233 can limit the limiting protrusion 225, preventing the limiting protrusion 225 from moving or rotating relative to the limiting groove 1233, causing the curtain bracket 2 to fall off the air conditioner 100, and making the connection between the curtain bracket 2 and the housing 1 more complete.

[0050] For example, the limiting rib 135 and the limiting protrusion 225 abut against each other in the second direction, and the limiting protrusion 225 is spaced apart from the first sidewall 1232.

[0051] For example, the limiting rib 135 abuts against the limiting protrusion 225 in the second direction, and the limiting protrusion 225 abuts against the first sidewall 1232 in the second direction. This allows the limiting groove 1233 to more effectively limit the limiting protrusion 225, preventing the limiting protrusion 225 from moving relative to the limiting groove 1233 in the second direction and causing the curtain bracket 2 to detach from the air conditioner 100.

[0052] For example, when installing the curtain bracket 2 on the housing 1, the first snap-fit ​​structure 131 and the second snap-fit ​​structure 221 can be aligned in the front-to-back direction. Then, the curtain bracket 2 can be moved until the first snap-fit ​​133 is engaged in the second snap-fit ​​hole 223. At this time, the limiting rib 135 is accommodated in the limiting notch 224, and the limiting protrusion 225 is accommodated in the limiting groove 1233. The curtain bracket 2 is then installed on the housing 1.

[0053] According to some embodiments of the present invention, the bottom wall 1231 of the groove is further provided with a fixing rib 1235, and the positioning groove 123 includes two second side walls 1234 arranged opposite to each other along the first direction. The fixing rib 1235 is located between the limiting rib 135 and the second side wall 1234. One end of the fixing rib 1235 is connected to the second side wall 1234, and the other end of the fixing rib 1235 is connected to the limiting rib 135.

[0054] For example, the bottom wall 1231 of the tank is provided with two fixing ribs 1235, and the two fixing ribs 1235 are arranged at intervals along the first direction.

[0055] By including a fixing rib 1235 in the air conditioner 100, and connecting one end of the fixing rib 1235 to the second side wall 1234 and the other end to the limiting rib 135, the fixing rib 1235 can improve the structural strength of the limiting rib 135, reduce the bending of the limiting rib 135 along the first direction, and more fully prevent the limiting protrusion 225 from bending relative to the limiting groove 1233 along the first direction, causing the limiting rib 135 to fail to cooperate with the limiting groove, and preventing the curtain bracket 2 from falling off the air conditioner 100.

[0056] For example, the limiting rib 135 located on the same side is connected to the first buckle 133 as a whole. By connecting one end of the fixing rib 1235 to the second side wall 1234 and the other end to the limiting rib 135, the fixing rib 1235 can reduce the bending of the limiting rib 135 in the first direction, thereby reducing the movement of the first buckle 133 in the first direction, making the connection between the first buckle 133 and the second locking hole 223 more stable, and more fully preventing the first buckle 133 from moving in the first direction and causing the first buckle 133 to disengage from the second locking hole 223, causing the curtain bracket 2 to fall off the air conditioner 100.

[0057] According to some embodiments of the present invention, the curtain bracket 2 includes a bracket body 210 and a support arm 211. The bracket body 210 is elongated and arranged in the left-right direction. The support arm 211 is one or multiple arms spaced apart in the left-right direction. The support arm 211 is connected to the front side of the bracket body 210, and the front end of the support arm 211 is provided with a second connecting structure 22.

[0058] For example, there can be one support arm 211, which is connected to the front side of the support body 210 and to the middle position of the support body 210 in the left-right direction.

[0059] For example, there can be two support arms 211, which are spaced apart in the left and right direction, and both support arms 211 are connected to the front side of the bracket body.

[0060] By making the curtain bracket 2 include the bracket body 210, and making the bracket body 210 long and set along the left and right directions, the air inlet 120 of the air conditioner 100 can be blocked by the curtain in both the left and right directions by the bracket body 210, which can more effectively prevent the curtain from blocking the air inlet and affecting the air intake.

[0061] By including a support arm 211 in the curtain bracket 2 and connecting the support arm 211 to the bracket body 210, the distance between the bracket body 210 and the air inlet 120 in the front-to-back direction can be increased, thus more effectively separating the curtain from the air inlet 120 and more effectively preventing the curtain from clogging the air inlet and affecting the air intake. By providing a second connecting structure 22 at the front end of the support arm 211, the support arm 211 can be connected to the first connecting structure 13 to mount the curtain bracket 2 onto the housing 1.

[0062] According to some embodiments of the present invention, at least one of the support body 210 and the support arm 211 has a cavity 212 formed therein, and a reinforcing rib 213 is provided in the cavity 212, and the reinforcing rib 213 is connected to the inner wall of the cavity 212.

[0063] For example, a cavity 212 is formed in the support body 210, and a reinforcing rib 213 is provided in the cavity 212, with the reinforcing rib 213 connected to the inner wall of the cavity 212.

[0064] For example, a cavity 212 is formed in the support arm 211, and a reinforcing rib 213 is provided in the cavity 212, with the reinforcing rib 213 connected to the inner wall of the cavity 212.

[0065] For example, both the support body 210 and the support arm 211 have cavities 212, and the cavities 212 are provided with reinforcing ribs 213, which are connected to the inner wall of the cavities 212.

[0066] By providing a reinforcing rib 213 inside the cavity 212 and connecting the reinforcing rib 213 to the inner wall of the cavity 212, the reinforcing rib 213 can increase the structural strength of the support body 210 or the support arm 211, reduce the bending or deformation of the support body 210 or the support arm 211, and enable the curtain bracket 2 to effectively separate the curtain from the air inlet 120.

[0067] For example, the reinforcing rib 213 forms an angle with the front-back or left-right directions. This allows the reinforcing rib 213 to form a more stable truss structure with the support body 210 or the support arm 211. The force exerted by the reinforcing rib 213 on the support body 210 or the support arm 211 has components in both the front-back and left-right directions, thus enhancing the structural strength of the curtain bracket 2.

[0068] According to some embodiments of this utility model, the reinforcing ribs 213 are arranged in multiple spaced intervals, and at least some adjacent reinforcing ribs 213 extend in different directions. By arranging the reinforcing ribs 213 in multiple spaced intervals, multiple positions of the support arm 211 or the bracket body 210 can be reinforced by the reinforcing ribs 213, thus enhancing the structural strength of the curtain bracket 2. By ensuring that at least some adjacent reinforcing ribs 213 extend in different directions, the reinforcing ribs 213 with different extension directions can support the bracket body 210 or the support arm 211 in multiple different directions, further enhancing the structural strength of the curtain bracket 2.

[0069] According to some embodiments of the present invention, the housing 1 includes a housing 11 and an air inlet grille 12. The curtain brackets 2 are multiple ones arranged at intervals along the vertical direction. The rear part of the housing 11 is provided with an installation port 112. The air inlet grille 12 is installed in the installation port 112 and forms an air inlet 120. The curtain brackets 2 are installed in the air inlet grille 12.

[0070] The air inlet grille 12 includes a grille portion 121 and a mounting portion 122. The mounting portions 122 are a plurality of portions spaced apart in the vertical direction. An air inlet 120 is formed between adjacent mounting portions 122. The grille portion 121 is located at the air inlet 120 and includes a horizontal grille strip extending in the left-right direction. The width dimension of the mounting portion 122 in the vertical direction is greater than the width dimension of the horizontal grille strip in the vertical direction. The curtain bracket 2 is mounted on the mounting portion 122.

[0071] For example, housing 11 may include front housing 110 and rear housing 111, wherein air outlet 113 is formed on front housing 110, and mounting port 112 is provided on rear housing 111, and air inlet grille 12 is mounted on mounting port 112 and forms air inlet 120.

[0072] By installing the curtain bracket 2 on the air inlet grille 12, which has an air inlet 120, the distance between the curtain bracket 2 and the air inlet 120 in the vertical or horizontal direction can be made closer. The curtain bracket 2 can more effectively prevent the curtain from blocking the air inlet 120 and affecting the air intake.

[0073] By having multiple mounting portions 122 spaced apart in the vertical direction, and by mounting curtain brackets 2 on the mounting portions 122, the air conditioner 100 may include one or more curtain brackets 2.

[0074] For example, the air conditioner 100 includes a curtain bracket 2, and at least one mounting part 122 is disposed at the center of the air inlet grille 12 in the vertical direction.

[0075] For example, the air conditioner 100 includes three curtain brackets 2, which are arranged at intervals in the vertical direction.

[0076] When the air conditioner 100 includes multiple curtain brackets 2, the multiple curtain brackets 2 are arranged at intervals in the vertical direction. This allows the air inlet grille 12 to be affected by the curtain brackets 2 separating the curtain from the air inlet 120 at multiple positions in the vertical direction. The curtain brackets 2 can more effectively prevent the curtain from blocking the air inlet and affecting the air intake.

[0077] By making the width of the mounting part 122 in the vertical direction greater than the width of the horizontal grille strip in the vertical direction, the mounting part 122 can have greater structural strength, thus more effectively preventing the curtain bracket 2 from falling off the housing 1.

[0078] The following reference Figures 1-7 This invention describes an air conditioner 100 according to some specific embodiments of the present invention.
