Detailed Description
In order that the above objects, features and advantages of the present invention can be more clearly understood, a more particular description of the invention will be rendered by reference to the appended drawings. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited by the specific embodiments disclosed below.
The technical solutions of some embodiments of the present invention are described below with reference to fig. 1 to 7.
As shown in fig. 1, the present embodiment provides a compressor accumulator 10, where the compressor accumulator 10 includes: a housing 100, a screen 600, a screen holder 700, and a partition 800. The housing 100 has an interior cavity 110. A screen 600 is disposed in the interior chamber 110. The screen holder 700 supports the screen 600. A partition 800 is provided in the inner chamber 110 for partitioning the inner chamber 110.
As shown in fig. 2, the compressor accumulator 10 provided in the present embodiment is one of important components of the compressor 1. The compressor 1 is used in an electric appliance having a heat and cold exchange function, such as a refrigerator, a freezer, an air conditioner, and an air cooler, and is configured to compress a refrigerant. The compressor liquid receiver 10 provided by the present embodiment is used in cooperation with the compressor body 20, and the two jointly constitute at least a part of the compressor 1. The compressor body 20 compresses a low-temperature and low-pressure refrigerant introduced thereinto, converts the low-temperature and low-pressure refrigerant into a high-temperature and high-pressure refrigerant, and then returns the high-temperature and high-pressure refrigerant to the refrigerant cycle system. The compressor receiver 10 is communicated with and engaged with the compressor body 20, and the compressor receiver 10 functions to suck the refrigerant from the compressor body 20, perform oil-gas separation on the refrigerant, and return the oil-gas separated refrigerant to the compressor body 20.
Compressor reservoir among the correlation technique is the easy vibration that produces of during operation, and the noise not only can be brought in the appearance of vibration, still can cause the influence to each part in the compressor reservoir, causes after long-time the use, and each part in the compressor reservoir is not hard up easily and the problem of damage.
In view of the above, the present embodiment provides the compressor accumulator 10 described above, so as to achieve the purpose of reducing vibration and noise of the compressor accumulator 10.
To achieve the above object, the present embodiment provides the filter 600, the filter holder 700 and the partition 800 inside the compressor accumulator 10, which are engaged with each other. Among other things, the screen 600 functions to filter the refrigerant entering the compressor accumulator 10 to remove impurities. However, the refrigerant introduced into the compressor accumulator 10 may impact the filter screen 600 during the filtering process, causing the filter screen 600 to be easily vibrated and loosened. Therefore, the present embodiment provides the screen bracket 700 below the screen 600 to support and stop the screen 600, which effectively prevents the screen 600 from vibrating when being impacted by the refrigerant, and supports and fixes the screen 600, thereby preventing the screen 600 from vibrating up and down and generating noise. On this basis, the present embodiment also provides a partition 800 in the compressor accumulator 10. The partition 800 separates the inner chambers 110 of the compressor accumulator 10 from each other. For example, as shown in fig. 1, the partition 800 divides the inner chamber 110 into a first chamber 112 and a second chamber 114 disposed one above the other. By arranging the partition plate 800 in the inner cavity 110, the refrigerant in a gas-liquid mixed state can be prevented from directly impacting the inner bottom wall of the compressor accumulator 10, and thus vibration and noise of the compressor accumulator 10 can be effectively reduced.
