[0084] Through the above scheme, the indoor heat exchanger design with multiple heat exchange sections is adopted, which can be arranged more flexibly according to the space in the air-conditioning indoor unit 100, thereby improving the space utilization rate.

[0087] In another embodiment, the threaded connector passes through the corresponding end plate and is then threadedly connected to the connection plate 120 .

[0094] In some embodiments, the second heat exchange section 400 and the third heat exchange section 500 are integrally formed and need to be manually bent.

[0095] In some embodiments, the third heat exchange section 500 and the fourth heat exchange section 600 are integrally formed and need to be manually bent.

[0096] In some embodiments, the first heat exchange section 300 , the second heat exchange section 400 , and the third heat exchange section 500 are integrally formed and need to be manually bent.

[0097] In some embodiments, the second heat exchange section 400, the third heat exchange section 500 and the fourth heat exchange section 600 are integrally formed and need to be manually bent.

[0098] In some embodiments, in some embodiments, the first heat exchange section 300, the second heat exchange section 400, the third heat exchange section 500 and the fourth heat exchange section 600 are integrally formed and need to be manually bent.

[0099] In some embodiments, the end plates respectively connected to the first heat exchange section 300 , the second heat exchange section 400 , the third heat exchange section 500 and the fourth heat exchange section 600 are respectively the first end plate 700 , the second end plate 800 , the third end plate 900 and the fourth end plate 110 .

[0100] In some embodiments, the first end plate 700 is connected to the connecting plate 120 via a positioning member 130 .

[0101] Furthermore, a positioning member 130 is disposed on the first end plate 700 , and a positioning hole 140 corresponding thereto is disposed on the connecting plate 120 .

[0102] In addition, a positioning member 130 may be provided on the connecting plate 120 , and a positioning hole 140 corresponding thereto may be provided on the first end plate 700 .

[0103] In some embodiments, the second end plate 800 is connected to the connecting plate 120 via a positioning member 130 .

[0104] Furthermore, a positioning member 130 is disposed on the second end plate 800 , and a positioning hole 140 corresponding thereto is disposed on the connecting plate 120 .

[0105] In addition, a positioning member 130 may be provided on the connecting plate 120 , and a positioning hole 140 corresponding thereto may be provided on the second end plate 800 .

[0106] In some embodiments, the third end plate 900 is connected to the connecting plate 120 via a positioning member 130 .

[0111] In addition, a positioning piece 130 may be provided on the connecting plate 120 , and a positioning hole 140 corresponding thereto may be provided on the fourth end plate 110 .

[0112] In some embodiments, only the first end plate 700 and the fourth end plate 110 are connected to the connection plate 120 through the positioning member 130. Because the first heat exchange section 300 and the fourth heat exchange section 600 are the two heat exchange sections at the edge, the connection plate 120 is quickly positioned and connected with the first end plate 700 and the fourth end plate 110 to ensure that the bending angle of the indoor heat exchanger as a whole can meet the requirements, which is convenient for production and manufacturing.

[0113] In some embodiments, the abutting portion on the first end plate 700 is a first abutting portion 701; and the abutting portion on the second end plate 800 is a second abutting portion 802. The first abutting portion 701 is used to abut against the second abutting portion 802. The angle between the first heat exchange section 300 and the second heat exchange section 400 is fixed by the abutment between the first abutting portion 701 and the second abutting portion 802.

[0114] In some embodiments, when the first abutting portion 701 and the second abutting portion 802 are in contact, the angle between the first heat exchange section 300 and the second heat exchange section 400 is A, and A is between 160° and 180°. This angle conforms to the design of the bending angle between the first heat exchange section 300 and the second heat exchange section 400 in most air conditioners.

[0115] When the angle between the first heat exchange section 300 and the second heat exchange section 400 is close to 160°, the space occupied between the first heat exchange section 300 and the second heat exchange section 400 is small.

[0116] When the angle between the first heat exchange section 300 and the second heat exchange section 400 is close to 180°, because the first heat exchange section 300 and the second heat exchange section 400 are close to parallel, the gap therebetween is smaller, which reduces air leakage and allows more air to pass through the first heat exchange section 300 and the second heat exchange section 400, thereby improving heat exchange efficiency.

[0117] In some embodiments, the second end plate 800 is further provided with a third abutting portion 803, and the abutting portion on the third end plate 900 is a fourth abutting portion 902. The third abutting portion 803 is used to abut against the fourth abutting portion 902. The abutting design of the third abutting portion 803 and the fourth abutting portion 902 fixes the angle between the third heat exchange section 500 and the third heat exchange section 500, which is convenient for production.

[0118] In some embodiments, when the third abutting portion 803 and the fourth abutting portion 902 are in contact, the angle between the first heat exchange section 300 and the second heat exchange section 400 is B, and B is between 120° and 150°. This angle is consistent with the design of the bending angle between the second heat exchange section 400 and the third heat exchange section 500 in most air conditioners.

[0119] When the angle between the second heat exchange section 400 and the third heat exchange section 500 is close to 120°, the space occupied between the second heat exchange section 400 and the third heat exchange section 500 is smaller.

[0120] When the angle between the second heat exchange section 400 and the third heat exchange section 500 is close to 150°, the gap between the second heat exchange section 400 and the third heat exchange section 500 is smaller, reducing air leakage, allowing more air to pass through the second heat exchange section 400 and the third heat exchange section 500, thereby improving heat exchange efficiency.

[0121] In some embodiments, a fifth abutment is further provided on the third heat exchange section 500, and a sixth abutment is further provided on the fourth heat exchange section 600, wherein the fifth abutment is used to abut against the sixth abutment. The angle between the third heat exchange section 500 and the fourth heat exchange section 600 is limited by the fifth abutment and the sixth abutment.

[0122] In some embodiments, when the fifth abutting portion and the sixth abutting portion are in contact, the angle between the third heat exchange section 500 and the fourth heat exchange section 600 is C, and C is between 60° and 120°. This angle conforms to the design of the bending angle between the third heat exchange section 500 and the fourth heat exchange section 600 in most air conditioners.

[0123] When the angle between the third heat exchange section 500 and the fourth heat exchange section 600 is close to 60°, the space occupied between the third heat exchange section 500 and the fourth heat exchange section 600 is smaller.

[0124] When the angle between the third heat exchange section 500 and the fourth heat exchange section 600 is close to 120°, the gap between the third heat exchange section 500 and the fourth heat exchange section 600 is smaller, reducing air leakage, allowing more air to pass through the third heat exchange section 500 and the fourth heat exchange section 600, thereby improving heat exchange efficiency.

[0125] In some embodiments, the indoor heat exchanger is used to bend in a first direction. A flange is provided on one side of the end plate close to the first direction, and the flange is bent close to the end plate adjacent thereto to form an abutment portion. The flange design makes the formation of the abutment portion simpler, thereby improving production efficiency and product quality.
