压缩机结构和制冷设备
Abstract:
一种压缩机结构（1）包括：壳体（11），壳体（11）内形成有容纳腔（110）；电机（12），设于容纳腔（110）内，电机（12）的轴向两端分别设有绕组（121）；曲轴箱（13），设于容纳腔（110）内，且曲轴箱（13）设于电机（12）的一端，曲轴箱（13）内设有与电机（12）传动连接的曲轴，其中，电机（12）靠近曲轴箱（13）的一端的绕组（121）上设有沿电机（12）的轴向向另一端凹陷的凹陷部（1211），曲轴箱（13）的一部分设于凹陷部（1211）围成的空间内。以及一种制冷设备。通过这种压缩机结构，曲轴箱（13）的一部分设于凹陷部（1211）围成的空间内，可将曲轴箱（13）整体下沉，在不影响内部曲轴箱（13）和电机（12）的尺寸的基础上，可以减少压缩机结构整体在电机的轴向方向的尺寸，利于压缩机小型化。
Abstract(English):

Provided is a compressor structure (1), comprising: a housing (11), with an accommodating chamber (110) being formed within the housing (11); an electric motor (12) arranged in the accommodating chamber (110), with two axial ends of the electric motor (12) being respectively provided with a winding (121); and a crankcase (13) arranged in the accommodating chamber (110), the crankcase (13) being arranged at one end of the electric motor (12), and the crankcase (13) being internally provided with a crankshaft which is in transmission connection with the electric motor (12), wherein the winding (121) at the end of the electric motor (12) close to the crankcase (13) is provided with a recess portion (1211) which is recessed towards the other end in the axial direction of the electric motor (12), and part of the crankcase (13) is arranged in a space enclosed by the recess portion (1211). Further provided is a refrigeration device. By means of the compressor structure, part of the crankcase (13) is arranged in the space enclosed by the recess portion (1211) to allow the whole crankcase (13) to be sunk, such that the size of the whole compressor structure in the axial direction of the electric motor can be reduced without affecting the sizes of the crankcase (13) and the electric motor (12) inside, which facilitates the miniaturization of the compressor.
