[0030] In existing air conditioners, the input and output pipes of the heat exchanger inside the shell are generally arranged between the back plate and the fresh air module. When installing the fresh air module, the installer's field of vision is blocked. If the input and output pipes of the heat exchanger are not properly placed, they are easily squeezed on the back plate shell by the fresh air module, which will cause the fresh air module to be assembled improperly and may also damage the input and output pipes of the heat exchanger, affecting the normal operation and heat preservation of the pipeline.

[0031] In view of this, the present invention proposes an air conditioner 100. The air conditioner 100 shown in the drawings of the present invention is a floor-standing air conditioner, so the following description is based on the floor-standing air conditioner. In addition, the air conditioner 100 can also be a wall-mounted air conditioner.

[0032] See also Figures 1 to 4 In one embodiment of the utility model, the air conditioner 100 includes a shell 1 and a heat exchanger 2, the shell 1 includes a front plate 11 and a back shell 12 connected to each other, the back shell 12 is provided with a groove body 121 protruding toward the front plate 11, and a receiving groove 1211 is formed in the groove body 121; the heat exchanger 2 is installed in the shell 1, and a heat exchanger input pipe 21 and a heat exchanger output pipe 22 are led out from the lower end of the heat exchanger 2, and the heat exchanger input pipe 21 and the heat exchanger output pipe 22 are received in the receiving groove 1211; wherein, the groove body 121 has an end face 1212 facing the front plate 11, and the end face 1212 is closer to the front plate 11 than the heat exchanger input pipe 21 and the heat exchanger output pipe 22.

[0033] Specifically, the shell 1 is the outer shell of the air conditioner 100. The shell 1 is used to accommodate and install the components and structures inside the air conditioner 100, and the shell 1 is used to protect the normal operation of the air conditioner 100 from external interference. In this embodiment, the shell 1 is formed by assembling multiple parts, wherein the shell 1 at least includes a front plate 11 and a back shell 12, and the front plate 11 and the back shell 12 are connected, wherein the front plate 11 and the back shell 12 can be directly connected or indirectly connected. An installation space is formed between the front plate 11 and the back shell 12 for installing components such as the heat exchanger 2 and the fresh air module 5. The back shell 12 is provided with a groove body 121 protruding toward the front plate 11, and a receiving groove 1211 is formed in the groove body 121. The receiving groove 1211 is used to receive multiple pipelines led out of the heat exchanger 2.

[0034] A heat exchanger 2 is installed in the housing 1. The heat exchanger 2 is used to realize the cooling function of the air conditioner. The heat exchanger 2 is installed in the housing 1. The heat exchanger 2 can be directly installed on the housing 1 or indirectly installed on the housing 1. In this embodiment, the heat exchanger 2 is installed on the heat exchanger bracket 3, and the heat exchanger 2 is installed on the housing 1 through the heat exchanger bracket 3.

[0038] Specifically, it should be noted that the trough body 121 includes a trough bottom 1213 and two baffles 1214, the two baffles 1214 are respectively connected to the trough bottom 1213, and the two baffles 1214 are used to limit the heat exchanger output pipe 22 and the heat exchanger input pipe 21, specifically in the radial direction of the above two, wherein the end face 1212 can be formed on any of the above baffles 1214.

[0039] Further, in one embodiment, see Figure 5 The cross section of the tank body 121 is U-shaped.

[0040] According to the previous embodiment, the trough body 121 includes a trough bottom 1213 and two baffles 1214. Furthermore, the cross-section of the trough body 121 is U-shaped, that is, the two baffles 1214 are parallel to each other, so that the two baffles 1214 can better restrict the heat exchanger input pipe 21 and the heat exchanger output pipe 22 in the receiving groove 1211.

[0041] In one embodiment, see Figure 4 The groove body 121 is provided with an opening 1215 on one side close to the heat exchanger 2 and connected to the accommodating groove 1211, and the heat exchanger input pipe 21 and the heat exchanger output pipe 22 are allowed to extend into the accommodating groove 1211 through the opening 1215. The accommodating groove 1211 is provided with a pipe outlet 1216 on the side away from the opening 1215, and the heat exchanger input pipe 21 and the heat exchanger output pipe 22 are allowed to extend out through the pipe outlet 1216.

[0046] According to the above embodiment, the accommodating groove 1211 has a groove bottom 1213. In addition, the accommodating groove 1211 also has a notch 1218 corresponding to the groove bottom 1213. A pipe clamp 4 is provided at the notch 1218. The heat exchanger input pipe 21 and the heat exchanger output pipe 22 are fixed in the accommodating groove 1211 by the pipe clamp 4 to prevent the heat exchanger input pipe 21 and the heat exchanger output pipe 22 from being exposed in the notch 1218, so that the heat exchanger input pipe 21 and the heat exchanger output pipe 22 are not affected when the fresh air module 5 is installed. The pipe clamp 4 is fixed to the back shell 12. The fixing method of the pipe clamp 4 and the back shell 12 can be screw connection or welding, which is not specifically limited here. The number of the pipe clamps 4 can be one, two, or more.

[0047] Furthermore, in one embodiment, see Figure 3 The number of the pipe clamps 4 is set to two, and the two pipe clamps 4 are arranged at intervals in the axial direction of the heat exchanger output pipe 22 .

[0048] Specifically, considering that if a tube clamp 4 is provided, one end of the heat exchanger input tube 21 or the heat exchanger output tube 22 may be lifted, in order to make the tube clamp 4 have a better limiting effect, the number of tube clamps 4 is set to at least two. In this embodiment, the number of tube clamps 4 is two, but not limited to this embodiment, the number of tube clamps 4 can also be multiple, and two or more tube clamps 4 are arranged at intervals in the axial direction of the heat exchanger output tube 22, that is, arranged at intervals in the length direction of the heat exchanger output tube 22, so that the heat exchanger input tube 21 and the heat exchanger output tube 22 can have a better limiting effect.

[0049] Preferably, in one embodiment, see Figure 3 , Figure 4 and Figure 6A mounting hole 41 is provided at one end of the tube clamp 4, and the tube clamp 4 is fixed to the back shell 12 by screws passing through the mounting hole 41. A slot 1219 is provided on the baffle 1214 away from the mounting hole 41, and the other end of the tube clamp 4 is inserted into the slot 1219.

[0050] It should be noted that a mounting hole 41 is provided at one end of the pipe clamp 4, and the pipe clamp 4 is fixed to the back shell 12 by screws passing through the mounting hole 41. In addition, in order to better fix the pipe clamp 4, a slot 1219 is provided on the baffle 1214 on the side away from the mounting hole 41, and the other end of the pipe clamp 4 is inserted into the slot 1219, so that the pipe clamp 4 can be better fixed.

[0051] Optionally, in one embodiment, see Figure 2 The air conditioner 100 also includes a heat exchanger bracket 3, the heat exchanger 2 is installed on the heat exchanger bracket 3, a water receiving tray 31 is provided at the bottom of the heat exchanger bracket 3, a guide pipe 311 is led out from one side of the water receiving tray 31 close to the tank body 121, and the guide pipe 311 is placed in the accommodating tank 1211.

[0052] The air conditioner 100 further includes a heat exchanger bracket 3, and the heat exchanger 2 is mounted on the heat exchanger bracket 3. The housing 1 is fixed by the heat exchanger bracket 3, so that the heat exchanger 2 is fixed on the housing 1.

The pipe clamp 4 also limits the flow guide pipe 311, and the tank 121 protects the flow guide pipe 311 to prevent the fresh air module 5 from interfering with the flow guide pipe 311 when it is installed.

[0053] Furthermore, in one embodiment, see Figure 5 The diameter of the flow guide pipe 311 is smaller than the diameter of the heat exchanger input pipe 21 and the diameter of the heat exchanger output pipe 22 , respectively. The flow guide pipe 311 is located between the heat exchanger input pipe 21 and the heat exchanger output pipe 22 .

[0054] It should be noted that the diameter of the flow guide pipe 311 is smaller than the diameter of the heat exchanger input pipe 21 and the diameter of the heat exchanger output pipe 22, so the flow guide pipe 311 is located between the heat exchanger input pipe 21 and the heat exchanger output pipe 22. Considering that the heat exchanger input pipe 21 and the heat exchanger output pipe 22 are both arranged in round tubes, the flow guide pipe 311 can occupy the position between the heat exchanger input pipe 21 and the heat exchanger output pipe 22 to the pipe clamp 4, thereby reducing the radial space occupied by the flow guide pipe 311, the heat exchanger input pipe 21 and the heat exchanger output pipe 22 as much as possible.
