Embodiment Construction

[0043] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0044] In order to achieve the purpose of the present invention, as Figure 2-3 As shown, in some embodiments of the scroll assembly of the present invention, it includes the movable scroll 6, the fixed scroll 7 and the first exhaust hole 82 opened at the center of the fixed scroll 6, the first exhaust An exhaust valve plate 8 is arranged on the hole 82, and two second exhaust holes 83 are opened on the static scroll 7, which are arranged symmetrically with respect to the first exhaust hole 82, and the two end compression chambers should be connected with the two exhaust holes at the same time. The two second exhaust holes 82 are connected, which can ensure the symmetry of the suction, compression and exhaust processes of the working chambers on both sides, and avoid additional unbalanced force and vibration; one or more meshes of the movable...

Abstract

The invention discloses a scroll plate component. The scroll plate component comprises a movable scroll plate, a static scroll plate and a first exhaust vent formed in the central position of the static scroll plate; at least one second exhaust vent is further formed in the static scroll plate; at least one meshing point of the movable scroll plate and the static scroll plate is tangent to the at least one second exhaust vent; the at least one second exhaust vent is communicated with the middle part of an exhaust cavity of the scroll plate component; the second exhaust vent is opened during a meshing process of the movable scroll plate and the static scroll plate; and after the second exhaust vent is opened, the movable scroll plate and the static scroll plate stop meshing. The invention also discloses a scroll compressor comprising the scroll plate component. Compared with the prior art, by adopting the scroll plate component disclosed by the invention, vibration and noise generated at the start-up initial period of the compressor can be effectively reduced.

Description

technical field [0001] The invention relates to the field of compressors, in particular to a scroll assembly and a scroll compressor including it. Background technique [0002] Electric scroll compressors are widely used in air-conditioning and refrigeration systems such as new energy vehicles. Such as figure 1 As shown, the exhaust hole 81 of this compressor is opened on the fixed scroll 7, and the gasoline mixture in the compressor is discharged into the rear cover exhaust hole through the exhaust hole. The static scroll with this structure mainly has the following disadvantages in use. When the compressor is started, due to the initial gas inside the compressor, the discharge pressure inside the compressor is too small at this time, and the opening area is small. The gas velocity of the hole is large, and the fluctuation is serious, resulting in unbalanced force, which will cause vibration and noise in the early stage of compressor startup. Contents of the invention ...
