an indoor heat exchanger and an indoor fan arranged in the indoor part;
an outdoor heat exchanger and an outdoor fan arranged in the outdoor part; and
a sealing assembly arranged in the receiving groove, and being rotatable around a rotation axis that is parallel to a length direction of the casing;
wherein the indoor part, the receiving groove, and the outdoor part are sequentially arranged along the length direction of the casing, the length direction being parallel to an indoor-outdoor direction.

2. The window air conditioner according to claim 1 , wherein:
the sealing assembly is configured to seal a space between a window and a window sill of a window opening when the window air conditioner is mounted at the window sill.

3. The window air conditioner according to claim 2 , wherein the sealing assembly comprises:
a first connecting component having a variable length, and comprising a fixing component and a sliding block, at least a part of the fixing component being arranged in the receiving groove, and the sliding block being slidably fitted with the fixing component; and
a plurality of second connecting components detachably connected to one another and configured to adjust a length of the sealing assembly, one of the second connecting components being detachably connected to the sliding block.

4. The window air conditioner according to claim 3 , wherein the sealing assembly further comprises a rotating bracket fixed at the casing, and the fixing component is rotatably arranged at the rotating bracket to enable the sealing assembly to be rotated to be stowed in the receiving groove.

5. The window air conditioner according to claim 4 , further comprising:
an angle-positioning assembly configured to cooperate with the rotating bracket and the fixing component to fix a position of the fixing component at an angle.

6. The window air conditioner according to claim 5 , wherein the angle-positioning assembly comprises:
a plurality of positioning recesses arranged in the rotating bracket and arranged in a ring; and
a positioning protrusion arranged at the fixing component and configured to be switchably fitted with one of the plurality of positioning recesses to fix a position of the fixing component.

7. The window air conditioner according to claim 3 , further comprising:
a slide-positioning assembly arranged at the fixing component and configured to cooperate with the sliding block to fix the sliding block at a position.

8. The window air conditioner according to claim 7 , wherein the fixing component includes a sliding cavity, and at least a part of the sliding block extends into the sliding cavity.

9. The window air conditioner according to claim 3 , wherein each of the second connecting components comprises an insertion portion, each of the second connecting components and the sliding block includes an insertion chamber, and each insertion portion is configured to be fitted with a corresponding insertion chamber in a pluggable manner.

10.
