Abstract
(EN) Disclosed are a compressor and a refrigerating device. The compressor (1) comprises a housing (10), a compression assembly (12), an electric motor (13), an oil sump (14), and an oil return channel (15). A cavity (11) is formed in the housing (10); and a part of the compression assembly (12) is connected to the housing (10) and located in the cavity (11), and the compression assembly (12) divides the cavity (11) into a first cavity (111) and a second cavity (112). A part of the electric motor (13) is arranged in the first cavity (111), and the part of the housing (10) that is located below the central axis of the electric motor (13) is a first housing (101). The oil sump (14) is arranged in the second cavity (112). The oil return channel (15) is arranged on the compression assembly (12), and the oil return channel (15) is provided with an oil inlet (151) facing the first cavity (111). The distance between a separation line in the oil inlet (151) and an inner side wall of the first housing (101) and the inner diameter of the housing (10) meet a preset relationship, and the area of an oil passing zone located below the separation line and the area of the oil inlet (151) meet a certain relationship, so that it is difficult for the oil inlet (151) to be exposed to a refrigerant, and the recycling efficiency of lubricating oil is improved, such that oil surface fluctuation is relatively stable, the oil discharge amount of the compressor (1) is reduced, and the reliability and the energy efficiency level of the compressor (1) are improved.
(FR) La présente invention concerne un compresseur et un dispositif de réfrigération. Le compresseur (1) comprend un logement (10), un ensemble de compression (12), un moteur électrique (13), un carter d'huile (14) et un canal de retour d'huile (15). Une cavité (11) est formée dans le logement (10) ; et une partie de l'ensemble de compression (12) est raccordée au logement (10) et située dans la cavité (11), et l'ensemble de compression (12) divise la cavité (11) en une première cavité (111) et une seconde cavité (112). Une partie du moteur électrique (13) est disposée dans la première cavité (111), et la partie du logement (10) qui est située au-dessous de l'axe central du moteur électrique (13) est un premier logement (101). Le carter d'huile (14) est disposé dans la seconde cavité (112). Le canal de retour d'huile (15) est disposé sur l'ensemble de compression (12), et le canal de retour d'huile (15) est pourvu d'une entrée d'huile (151) faisant face à la première cavité (111). La distance entre une ligne de séparation dans l'entrée d'huile (151) et une paroi latérale interne du premier logement (101) et le diamètre intérieur du logement (10) satisfont à une relation prédéfinie, et la surface d'une zone de passage d'huile située sous la ligne de séparation et la surface de l'entrée d'huile (151) satisfont à une certaine relation, de sorte qu'il est difficile pour l'entrée d'huile (151) d'être exposée à un fluide frigorigène, et l'efficacité de recyclage de l'huile de lubrification est améliorée, de telle sorte que la fluctuation de surface d'huile est relativement stable, la quantité d'évacuation d'huile du compresseur (1) est réduite, et la fiabilité et le niveau d'efficacité énergétique du compresseur (1) sont améliorés.
(ZH) 一种压缩机和制冷装置,压缩机(1)包括壳体(10)、压缩组件(12)、电机(13)、油池(14)和回油通道(15)。壳体(10)构造出腔体(11);压缩组件(12)的一部分与壳体(10)连接并位于腔体(11)内,压缩组件(12)将腔体(11)分为第一腔体(111)和第二腔体(112)。电机(13)的一部分设置在第一腔体(111)内,位于电机(13)的中心轴线下方的部分壳体(10)为第一壳体(101)。油池(14)设置在第二腔体(112)内。回油通道(15)设置在压缩组件(12)上,回油通道(15)具有朝向第一腔体(111)的进油口(151)。通过令进油口(151)内的分隔线与第一壳体(101)的内侧壁之间的距离与壳体(10)的内径满足预设关系,且位于分隔线下的通油区的面积与进油口(151)面积满足一定关系,从而使进油口(151)难以暴露在冷媒中,提升润滑油的回收效率,使得油面波动相对平稳,降低压缩机(1)的吐油量并提升压缩机(1)的可靠性和能效等级。
