DETAILED DESCRIPTION

Hereinafter, technical solutions of the embodiments of the present application will be described clearly and completely in conjunction with the drawings of the embodiments of the present application. Apparently, the described embodiments are a part, but not all, of the embodiments of the present application. All other embodiments, which are obtained by those having ordinary skills in the art based on the embodiments in the present application without exercising any inventive skills, fall within the scope of protection of the present application.

As shown in FIG. 1, an embodiment of the present application provides a compressor comprises a housing 10, a partition plate 20, a fixed scroll 30, an orbiting scroll 40, a floating plate assembly 50 and a seal 60. The partition plate 20 is disposed in an accommodating cavity of the housing 10 and divides the accommodating cavity into a first accommodating cavity 11 and a second accommodating cavity 12 which have different pressures inside. The floating plate assembly 50 and the seal 60 are both located between the partition plate 20 and the fixed scroll 30. The floating plate assembly 50 comprises at least two floating plates, and the seal 60 comprises at least one of a first sealing portion 61 and a second sealing portion 62. The first sealing portion 61 is connected to a inner edge of a relatively inwardly arranged floating plate of the at least two floating plates, and the second sealing portion 62 is connected to an outer edge of a relatively outwardly arranged floating plate of the at least two floating plates.

Working principle of the embodiments of the present application can be formulated as follows.

Since the compressor comprises the seal 60 which includes at least one of the first and second sealing portions 61 and 62, the sealing performance of the compressor is enhanced, which ensures a good sealing performance of the compressor. Meanwhile, since the first sealing portion 61 comprised in the seal 60 is connected to the inner edge of the relatively inwardly arranged floating plate of the at least two floating plates and the second sealing portion 62 comprised in the seal 60 is connected to the outer edge of the relatively outwardly arranged floating plate of the at least two floating plates, fixing performance of the first and second sealing portions 61 and 62 is improved, which reduces the occurrence of movement of the first and second sealing portions 61 and 62 during operation of the compressor, and enhances the sealing reliability of the compressor.

The first accommodating cavity 11 can be referred to as an exhaust area, and the second accommodating cavity 12 can be referred to as a suction area, and pressure in the first accommodating cavity 11 can be greater than that in the second accommodating cavity 12.

The partition plate 20 is configured to separate the first accommodating cavity 11 from the second accommodating cavity 12, and optionally, the partition plate 20 can abut with two opposite side walls of the housing 10, so as to dividing the accommodating cavity into the first and second accommodating cavities 11 and 12.

However, volumes of the first and second accommodating cavities 11 and 12 are not limited herein, and optionally, volume of the first accommodating cavity 11 can be smaller than that of the second accommodating cavity 12.

It should be noted that the number of the floating plates comprised in the floating plate assembly 50 is not limited herein, and the number can be 2, 3, 4, or the like.

The inner edge of the relatively inwardly arranged floating plate of the at least two floating plates may be understood as follows: the at least two floating plates are arranged in a misaligned manner, so that there must be a relatively inwardly arranged floating plate among the at least two floating plates in the misalignment arrangement, and the inner edge of the relatively inwardly arranged floating plate of the at least two floating plates may refer to a inner edge of said floating plate on which a through-hole or a groove is provided, or if said floating plate and other floating plate(s) encircle a through-hole or a groove therebetween, the inner edge of said floating plate may refer to a portion of said floating plate which is corresponding to a inner edge of the through-hole or of the groove.

For example, the relatively inwardly arranged floating plate of the at least two floating plates may be understood as follows: when there are two floating plates which are arranged in a misaligned manner and perform orthogonal projection to these two floating plates, if most of an orthogonal projection of one floating plate is overlapped by an orthogonal projection of the other floating plate and the orthogonal projection of the other floating plate is greater than that of the one floating plate in a non-overlapping part, then the one floating plate may be regarded as being relatively inwardly arranged, and the other floating plate regarded as being relatively outwardly arranged.

For another example, when there are three floating plates which are arranged in a misaligned manner and perform orthogonal projection to these three floating plates, a floating plate which has its orthogonal projection located between the orthogonal projections of the other two floating plates is regarded as being relatively inwardly arranged, while the other two floating plates can be regarded as being relatively outwardly arranged.

The outer edge of the relatively outwardly arranged floating plate of the at least two floating plates may be understood as follows: the at least two floating plates are arranged in a misaligned manner, so that there must be a relatively outwardly arranged floating plate among the at least two floating plates in the misalignment arrangement, and the outer edge of the relatively outwardly arranged floating plate of the at least two floating plates may refer to an outer edge of the relatively outwardly arranged floating plate of the at least two floating plates in the misalignment arrangement.

Similarly, for the explanation of the outer edge of the relatively outwardly arranged floating plate of the at least two floating plates, reference can be made to the above-mentioned example of the relatively inwardly arranged floating plate of the at least two floating plates, which will not be repeated herein.

It should be noted that, as an optional embodiment, the compressor may further comprise a connector located between the fixed scroll 30 and the floating plate assembly 50 and provided with a groove, in which groove the floating plate assembly 50 is disposed.

As an optional embodiment, referring to FIG. 1, a back pressure chamber 70 is encircled between the fixed scroll 30 and the floating plate assembly 50, and a plurality of compression chambers 71 are encircled between the fixed and orbiting scrolls 30 and 40. The back pressure chamber 70 is in communication with at least part of the plurality of compression chambers 71, the first sealing portion 61 separates the back pressure chamber 70 from the first accommodating cavity 11, and the second sealing portion 62 separates the back pressure chamber 70 from the second accommodating cavity 12.

The back pressure chamber 70 can be in communication with one of the plurality of compression chambers 71, and the plurality of compression chambers 71 can be sequentially spaced apart.

In the embodiment of the present application, due to the fact that the fixed scroll 30 and the floating plate assembly 50 encircle the back pressure chamber 70 therebetween, and the first sealing portion 61 separates the back pressure chamber 70 from the first accommodating cavity 11 and the second sealing portion 62 separates the back pressure chamber 70 from the second accommodating cavity 12, the sealing performance of the back pressure chamber 70 is enhanced and solves the problem in relation to sealing of the back pressure chamber 70.
