On the other hand, the temperature sensing portion 31 of the temperature sensor 3 is arranged opposite to the air inlet 11 and has an air flow, so that the temperature of the air flow at the air inlet 11 can be better detected, and the detection result is more accurate.

[0082] In addition, the mounting portion 2 is arranged at the lower end of the air inlet 11 to avoid affecting the appearance of the air conditioner 100 if the mounting portion 2 is arranged at the middle position of the air inlet 11. At the same time, the electric control box assembly 5 is arranged on the inner side of the rear shell 1 and on the lower side of the air inlet 11. Arranging the mounting portion 2 at the lower end of the air inlet 11 facilitates the connection between the wire body 32 of the temperature sensor 3 and the electric control box assembly 5, can shorten the length of the wire body 32, reduce the cost, and make the wiring in the interior of the air conditioner 100 more orderly. The electric control box assembly 5 can supply power to the temperature sensor 3 and effectively process the measurement information of the temperature sensor 3.

[0083] Optionally, the mounting portion 2 and the rear shell 1 are an integral piece.

[0084] According to the rear shell assembly 10 of the embodiment of the utility model, by setting the mounting portion 2 on the inner side of the rear shell 1, the mounting portion 2 is opposite to the air inlet 11 and is located at the lower end of the air inlet 11, the temperature sensing portion 31 of the temperature sensor 3 is arranged on the mounting portion 2, not only can make the temperature sensor 3 be arranged on the rear shell 1, can make the temperature sensor 3 and the rear shell 1 go out together, improve cooperation, improve production efficiency, can also make the position of the temperature sensing portion 31 of the temperature sensor 3 be at the position of airflow circulation, can better detect the airflow temperature at the air inlet 11, and the detection result is more accurate.

Therefore, the mounting portion 2 can be located at the lower end of the air inlet 11, improving the appearance effect of the air inlet 11 and facilitating the connection between the wire body 32 of the temperature sensor 3 and the electric control box assembly 5, and the first ribs 121 can also avoid blocking the airflow, so that the airflow flows from the lowermost first air inlet 111 to the temperature sensing portion 31, improving the accuracy of the detection result of the temperature sensor 3.

[0086] In addition, as shown in Figure 7 and Figure 8 , referring to Figure 5 , the air inlet grille 12 further includes a plurality of second ribs 122 spaced apart along the width direction of the rear shell 1, the second ribs 122 extend along the up-down direction, the plurality of first ribs 121 and the plurality of second ribs 122 are arranged alternately and connected, and along the width direction of the rear shell 1, the temperature sensing portion 31 is arranged in a staggered manner with the second ribs 122. It can be understood that, along the width direction of the rear shell 1, the temperature sensing portion 31 can be located between two adjacent second ribs 122, the plurality of second ribs 122 can further divide the first air inlet 111 into a plurality of second air inlets 1111 spaced apart along the width direction of the rear shell 1, and the temperature sensing portion 31 is arranged opposite to the second air inlets 1111. The second ribs 122 can also avoid blocking the airflow, so that the airflow flows from the lowermost second air inlet 1111 to the temperature sensing portion 31, improving the accuracy of the detection result of the temperature sensor 3.

[0087] In some embodiments of the utility model, as shown in Figure 10 , referring to Figure 17The mounting portion 2 has a rear side wall 21 located between the temperature sensing portion 31 and the air inlet grille 12, and it can be understood that the temperature sensing portion 31 is located downstream of the rear side wall 21 along the airflow direction. In order to avoid that the rear side wall 21 blocks the airflow and affects the temperature sensing portion 31 to detect the temperature of the airflow, the rear side wall 21 is provided with a ventilation hole 23, and at least a part of the temperature sensing portion 31 is arranged opposite to the ventilation hole 23, so that the airflow entering from the air inlet 11 can flow to the temperature sensing portion 31 through the ventilation hole 23, and the temperature sensing portion 31 is located in the airflow, which can better detect the temperature of the airflow at the air inlet 11, and the detection result is more accurate.

[0088] Further, as shown in Figure 8 , the ventilation holes 23 are arranged in a plurality of intervals, and the plurality of ventilation holes 23 are arranged in intervals in the width direction of the rear shell 1.

Thereby, the ventilation area of the ventilation hole 23 can be further increased, so that the airflow can better flow to the temperature sensing portion 31 through the ventilation hole 23, the airflow flowing at the position of the temperature sensing portion 31 is better, the temperature of the airflow at the air inlet 11 can be better detected, and the detection result is more accurate.

[0090] In some embodiments of the utility model, as shown in Figure 3 , the rear shell assembly 10 further comprises a filter screen 4, and the filter screen 4 is located downstream of the air inlet grille 12 and upstream of the heat exchange component 6 along the airflow direction, and is used for filtering dust in the airflow entering the main air duct 71 from the air inlet 11.
