[0024] The principles and features of the present application are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present application and are not used to limit the scope of the present application.

[0025] like Figure 1 and Figure 2 As shown, an embodiment of the present application provides an air conditioner, comprising: an air conditioner main body 1 and an exhaust fan 2. The exhaust fan 2 is located on one side of the air conditioner main body 1, and is configured to be fixedly connected to the air conditioner main body 1 by a fastener. The air conditioner main body 1 can be an indoor unit of a split air conditioner, or an integrated unit. The air conditioner can be a bathroom air conditioner, but is certainly not limited to a bathroom air conditioner, and can also be a kitchen air conditioner.

[0026] Among them, Figures 3 to 6 As shown, one of the exhaust fan 2 and the air conditioner body 1 is provided with a hook 211, and the other is provided with a slot 111. The hook 211 is configured to be inserted into the slot 111 to limit the downward movement of the exhaust fan 2 relative to the air conditioner body 1 (for example: limit the exhaust fan 2 from tilting and rotating downward relative to the air conditioner body 1, limit the exhaust fan 2 from moving downward relative to the air conditioner body 1, etc.). In other words, the cooperation between the hook 211 and the slot 111 can limit the downward movement of the exhaust fan 2, thereby sharing a part of the shear force.

[0027] In the related art, the exhaust fan 2 is connected to the air conditioner body 1 only by fasteners. As an independent module, the exhaust fan 2 is heavy, which causes the fasteners to be subjected to downward shear force for a long time, and they are easy to loosen, produce vibration and abnormal noise, or even fall off.

[0028] The air conditioner provided in the embodiment of the present application adds the cooperation of the hook 211 and the slot 111 on the basis of the original fastener connection. The cooperation of the hook 211 and the slot 111 can share part of the shear force, thereby reducing the shear force on the fastener, thereby reducing the risk of the fastener loosening, causing vibration, abnormal sound, or even falling off. In addition, the cooperation of the hook 211 and the slot 111 can pre-fix the exhaust fan 2, facilitate the subsequent installation of fasteners, and facilitate on-site construction.

[0029] In some exemplary embodiments, Figure 1 As shown, the air conditioner body 1 includes a casing 11, and the exhaust fan 2 includes a shell 21. The casing 11 and the shell 21 are fixedly connected by fasteners. The casing 11 of the air conditioner body 1 can be a sheet metal part, and the shell 21 of the exhaust fan 2 can also be a sheet metal part. The casing 11 of the air conditioner body 1 can be provided with a flange, and the shell 21 of the exhaust fan 2 can also be provided with a flange. The flange of the casing 11 and the flange of the shell 21 are fixedly connected by fasteners (such as screws). The number of fasteners can be multiple, for example, one fastener is provided at each of the four corners of the top, bottom, left and right.

[0030] like Figure 2 and Figure 3 As shown, the slot 111 is provided on the casing 11, and the hook 211 is provided on the outer shell 21. The hook 211 is configured to be inserted into the slot 111 and to hook the inner wall of the casing 11 upwards to limit the exhaust fan 2 from tilting downward relative to the air conditioner body 1.

[0031] In the related art, the fasteners on the upper side are subjected to greater shear force, so the fasteners on the upper side are more likely to loosen, making it easy to form a gap between the upper part of the exhaust fan 2 and the casing 11, which can be manifested as the exhaust fan 2 tilting downward and rotating as a whole. However, in this solution, the hook 211 can hook the inner wall of the casing 11 upward, so that when the exhaust fan 2 tilts downward and rotates, it will be subject to the blocking force applied by the casing 11, thereby limiting the exhaust fan 2 from tilting downward and rotating, and transferring part of the shear force to the casing 11 of the air conditioner body 1, which is conducive to improving the stability and fixing reliability of the exhaust fan 2.

[0032] The hook 211 may be disposed at the middle and upper portion of the housing 21 of the exhaust fan 2, which is beneficial to improving the effect of sharing the shear force.

[0033] In other embodiments, the positions of the hook 211 and the slot 111 may be swapped, the hook 211 may be set on the casing 11 of the air conditioner body 1, and the slot 111 may be set on the outer shell 21 of the exhaust fan 2. When the exhaust fan 2 wants to tilt downward, the hook 211 of the casing 11 may also hook the inner wall of the outer shell 21, exerting a blocking force, thereby limiting the exhaust fan 2 from tilting downward. In addition, the hook 211 can also support the exhaust fan 2, limiting the exhaust fan 2 from moving downward relative to the air conditioner body 1. In this way, part of the shear force of the exhaust fan 2 can be better transferred to the air conditioner body 1, which is conducive to improving the stability and fixing reliability of the exhaust fan 2.

[0034] In some exemplary embodiments, a support step 1112 is provided in the slot 111. Figure 3 and Figure 4 As shown, the supporting step 1112 is configured to support the bottom of the hook 211 to limit the exhaust fan 2 from moving downward relative to the air conditioner body 1 .

[0035] In this way, the cooperation between the slot 111 and the hook 211 plays a dual limiting role, which can better transfer a part of the shear force of the exhaust fan 2 to the air conditioner body 1, which is beneficial to improving the stability and fixing reliability of the exhaust fan 2.

[0036] In some exemplary embodiments, Figures 3 to 5 As shown, the card slot 111 includes an insertion slot 1113 and a limiting slot 1111 which are connected to each other, and the support step 1112 is located between the insertion slot 1113 and the limiting slot 1111 and at the bottom of the limiting slot 1111. The hook 211 is configured to be inserted into the card slot 111 through the insertion slot 1113, and to be limited in the limiting slot 1111 after sliding to the limiting slot 1111.

[0037] This makes it easy for the hook 211 to be smoothly inserted into the slot 111, and the installation process of the hook 211 and the slot 111 can be achieved without tilting the exhaust fan 2, which is beneficial to reducing the difficulty of installing the exhaust fan 2 and improving assembly efficiency.

[0038] In some exemplary embodiments, Figures 3 to 5 As shown, the card slot 111 further includes a transition slot 1114 between the insertion slot 1113 and the limiting slot 1111, and a communication opening 1116 is provided between the transition slot 1114 and the limiting slot 1111. The hook 211 is configured to undergo elastic deformation (the sheet metal may undergo micro-deformation) during the process of moving from the insertion slot 1113 to the communication opening 1116 to pass through the transition slot 1114 and the communication opening 1116, and to undergo reset deformation after passing through the communication opening 1116 to be limited in the limiting slot 1111.

[0039] In this way, after the hook 211 enters the limiting groove 1111 , it will be limited by the supporting step 1112 , which helps to prevent the hook 211 from returning to the insertion groove 1113 by crossing the connecting port 1116 under the action of gravity after entering the limiting groove 1111 .

[0040] In some exemplary embodiments, Figures 3 to 5 As shown, the transition groove 1114 is provided with a guiding inclined surface 1115 , and the guiding inclined surface 1115 is configured to guide the hook 211 to slide from the insertion groove 1113 to the communication port 1116 , so as to enter the limiting groove 1111 through the communication port 1116 and be limited in the limiting groove 1111 .

[0041] This makes it easier for the hook 211 to pass through the transition groove 1114 and the connecting port 1116 , which helps to reduce the difficulty of installing the exhaust fan 2 and improve the assembly efficiency.

[0042] In one embodiment, Figures 3 to 5 As shown, the guide slope 1115 is connected to one end (the inner end) of the support step 1112 close to the communication port 1116. In the width direction of the slot 111, the insertion slot 1113, the transition slot 1114 and the limiting slot 1111 are flush with one side wall (the inner wall) away from the support step 1112.

[0043] like Figure 6 As shown, the hook 211 includes a connecting section 2111 extending laterally and a hooking section 2112 extending upward, and the hooking section 2112 is connected to the connecting section 2111. The hooking section 2112 is configured to hook the inner side wall of the housing 11, and the connecting section 2111 is configured to abut against the supporting step 1112. The width of the limiting groove 1111 is equal to the width of the insertion groove 1113. The thickness direction of the hook 211 is consistent with the width direction of the insertion groove 1113.

[0044] The height of the slot 111 is recorded as A, the height of the insertion slot 1113 is recorded as B, the height of the limit slot 1111 is recorded as C, the width of the connecting port 1116 is recorded as D, the width of the insertion slot 1113 is recorded as E, the thickness of the hook 211 is recorded as H, the height of the hook 211 is recorded as J, and the height of the connecting section 2111 is recorded as I.

[0045] Among them, A>I+J, B>J, J>C>I, D>H, E>H.

[0046] B>J and E>H ensure that the hook 211 can be horizontally inserted into the insertion groove 1113 of the slot 111. C>I and E>H ensure that the connecting section 2111 of the hook 211 can be inserted into the limiting groove 1111. C<J ensure that the hook section 2112 of the hook 211 can hook upwards onto the inner side wall of the housing 11. D>H ensure that the hook 211 can pass through the communication port 1116.

[0047] In some embodiments, 1mm≤CI≤2mm. In this way, there is a suitable assembly gap between the connecting section 2111 of the hook 211 and the limiting groove 1111 of the slot 111 in the height direction, which is beneficial to avoid the gap being too small to affect the installation convenience, and also to avoid the gap being too large to affect the stability after assembly.

[0048] In some embodiments, E>2H is beneficial to increase the horizontal distance between the hook 211 and the connecting port 1116 in the natural state, thereby preventing the hook 211 from entering the limiting groove 1111 and then crossing the connecting port 1116 under the action of gravity and returning to the insertion groove 1113, thereby improving the position stability and use reliability of the hook 211.

[0049] In some exemplary embodiments, Figure 2 As shown, there are two hooks 211, which are arranged at intervals in the horizontal direction. There are two slots 111, which are arranged at intervals in the horizontal direction.

[0050] The distance between the outer end faces of the two hooks 211 is recorded as F, the distance between the outer end faces of the two slots 111 is recorded as G, the distance between the inner end faces of the two hooks 211 is recorded as K, and the distance between the two support steps 1112 is recorded as L. The outer end face of the hook 211 refers to the end face of one hook 211 away from the other hook 211. The inner end face of the hook 211 refers to the end face of one hook 211 close to the other hook 211. The outer end face of the slot 111 refers to the end face of the slot 111 away from the other slot 111.

[0051] Among them, G≥F, K>L. In this way, it can be ensured that the hook 211 needs to undergo elastic deformation before passing through the communication opening 1116, and can be limited in the limiting groove 1111 after reset deformation, and will not pass through the communication opening 1116 in the reverse direction.

[0052] Furthermore, 0≤GF≤0.5H. If the difference is too large, the shear force sharing effect of the hook 211 and the groove 111 will be weakened.

[0053] The above-mentioned air conditioner provided in the embodiment of the present application, the structural arrangement of the card slot 111 and the card hook 211 can also realize two installation processes: pre-ceiling installation and post-ceiling installation. The pre-ceiling installation process refers to connecting the exhaust fan 2 with the air conditioner body 1 before hanging, and then hanging the whole. The post-ceiling installation process refers to installing the exhaust fan 2 on the air conditioner body 1 after the air conditioner body 1 is hung.

[0054] The installation process before ceiling hanging is as follows: before ceiling hanging, the air conditioner main body 1 and the exhaust fan 2 can be placed upside down, so that the panel of the air conditioner main body 1 faces upward, the insertion slot 1113 is on the top, the limit slot 1111 is on the bottom, and the hook section 2112 of the hook 211 of the exhaust fan 2 extends downward. The hook 211 is inserted from the insertion slot 1113 of the slot 111, and pressed down with force. Through the micro deformation of the sheet metal, the hook 211 slides into the limit slot 1111 of the slot 111, and the deformation of the hook 211 is restored. At this time, the slot 111 plays a positioning role. Then the exhaust fan 2 is locked with the air conditioner main body 1 with screws. When hoisting, the whole formed by the air conditioner main body 1 and the exhaust fan 2 is turned upside down (upside down). After hoisting, the hook 211 can be clamped downward to the support step 1112, and the support step 1112 can withstand the shear force of the exhaust fan 2 to avoid the reliability risk caused by the loosening of the screws.

[0055] The installation process after the ceiling is suspended is as follows: After the air conditioner body 1 is hoisted, the hook 211 of the exhaust fan 2 is inserted from the insertion slot 1113 of the slot 111, and it is pushed upward with force. Through the slight deformation of the sheet metal, the hook 211 slides into the limit slot 1111 of the slot 111, and the deformation of the hook 211 is restored. After hoisting, the hook 211 is stuck to the support step 1112, and the support step 1112 can withstand the shear force of the exhaust fan 2. At this time, you can let go and proceed with the subsequent installation, freeing your hands and allowing single-person operation. The support step 1112 can withstand the shear force of the exhaust fan 2, avoiding reliability risks caused by loose screws.
