[0004] The existing electric scroll compressor stator plate structure uses bolts to install the stator plate to the inside of the compressor housing. However, the bolt installation requires tools for convenient disassembly and assembly, which makes operation inconvenient. In addition, the stator plate adopts a closed annular structure and uses an air inlet hole to absorb air, which results in a low air transmission coefficient of the compressor, reducing the practicality of the device. Therefore, it is urgent to design an electric scroll compressor stator plate structure that is easy to assemble to solve the above problems. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an electric scroll compressor stator structure that is easy to assemble, comprising: a stator scroll body, an assembly structure is arranged on the upper end of the stator scroll body, a practical structure is arranged above the stator scroll body, the assembly structure comprises a stator support portion, the stator support portion is fixedly arranged on the upper end of the stator scroll body, an installation cavity is provided inside the stator support portion and the stator scroll body, a mounting rod is inserted into the mounting cavity, an insertion rod is inserted inside the mounting rod, a pull rod is fixedly connected to the upper end of the insertion rod, an end of the insertion rod away from the mounting rod is inserted inside the insertion cavity, and the insertion cavity is provided inside the stator disk support portion.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The electric scroll compressor stator plate structure which is easy to assemble is provided with an assembly structure. When assembling the electric scroll compressor stator plate structure, it is directly installed into the electric scroll compressor housing. First, the pull rod is pulled to drive the insertion rod to move away from the installation cavity, and then the stationary scroll plate body is installed into the electric scroll compressor housing. At this time, the installation rod is synchronously inserted into the installation cavity for installation. The pull rod is released, and the spring is in a compressed and force-accumulating state. The pull rod is released, and the elastic force of the spring can automatically drive the insertion rod to engage into the installation rod, so that the electric scroll compressor stator plate structure can be conveniently assembled.

The stator plate structure sets the air inlet part between two groups of stator plate support parts. Compared with the setting of the existing air inlet hole, the air inlet area is larger, and the air transmission coefficient of the air inlet part becomes higher, thereby improving the efficiency of the electric scroll compressor. The stator plate support part is set at the upper end of the stator plate body along the circumference of the stator plate body, and no longer adopts a closed annular setting. On the one hand, it can reduce the amount of material used in the production of the stator plate structure, and on the other hand, it can make the stator plate structure lighter and smaller in size, making it more convenient to use. By using two groups of drainage holes at the bottom end of the stator plate body, liquid can be discharged in advance when liquid accumulates in the compression chamber inside the vortex profile. A groove is opened inside the upper end of the vortex profile, and a sealing strip can be installed in the groove to ensure the sealing effect when the vortex plate is working. Through this design, the stator plate structure of the electric scroll compressor which is easy to assemble no longer adopts a closed annular setting. On the one hand, it can reduce the amount of material used in the production of the stator plate structure, and on the other hand, it can make the stator plate structure lighter and smaller in size, thereby improving the practicality of the device.

Two groups of drainage holes are opened at the bottom end of the static scroll disk body 111. When liquid accumulates in the compression chamber inside the vortex profile 312, the liquid can be discharged in advance. A groove is opened inside the upper end of the vortex profile 312, and a sealing strip can be assembled in the groove to ensure the sealing effect of the scroll disk when it is working. The operation is now completed.
