For example, the invention patent application with the publication number CN109058111A discloses a floating axial seal structure. In this solution, a low-pressure sealing section, a medium-pressure sealing section and a high-pressure sealing section are respectively set. However, if the floating pressure of the sealing strip is too large, the It is easy to cause wear, and if the floating pressure on the sealing strip is too small, the sealing performance will be poor

Embodiment Construction
[0026] Embodiment 1 of scroll assembly, scroll compressor and electrical appliances:
[0027] The electrical appliance in this embodiment may be, for example, a refrigerator, an air conditioner, etc. Taking a split type air conditioner as an example, the scroll compressor is installed in an outdoor unit of the split type air conditioner.
[0028] The scroll assembly of this embodiment is applied to the scroll compressor of this embodiment. For example, the scroll assembly of this embodiment may be used for the movable scroll, or the scroll assembly of this embodiment may be used for the fixed scroll. The scroll assembly, of course, can also use the scroll assembly of this embodiment for both the movable scroll and the fixed scroll, please refer to figure 1 , the movable scroll of the scroll compressor in this embodiment will be described using the scroll assembly in this embodiment as an example.
[0029] Please refer to Figure 1 to Figure 3 , the scroll assembly includes a...

The invention relates to the field of scroll compressors. A scroll plate assembly comprises a scroll plate and a sealing strip, wherein the scroll plate is provided with scroll wraps, the top of the scroll wraps is provided with a sealing groove extending in the extending direction of the scroll wraps, the sealing strip extends in the extending direction of the sealing groove, the sealing strip isarranged in the sealing groove, drainage grooves are formed in the scroll wraps, and the drainage grooves communicate with the sealing groove and an intertooth groove of the scroll plate. When the scroll plate assembly is used, a refrigerant in all parts of the sealing groove is introduced by the drainage grooves, the pressure of the refrigerant on all parts of the sealing strip is equivalent, the sealing strip floats under the action of the refrigerant pressure until the sealing strip abuts against the scroll plate matched with the sealing strip in a sealing manner, and the sealing functionis achieved. Due to the fact that the pressure of the refrigerant on all parts of the sealing strip is equivalent, as long as the drainage grooves in suitable positions are selected to provide the refrigerant with the proper pressure for the sealing groove, the sealing strip can be floated up under the proper pressure, so that the sealing strip can be prevented from failing due to excessive wear,and it is beneficial to ensure that the sealing strip is effectively sealed for a long term.
Description
technical field [0001] The invention relates to the field of scroll compressors, in particular to a scroll assembly, a scroll compressor and an electrical appliance. Background technique [0002] When the scroll compressor is running, multiple independent compression chambers are formed between the orbiting scroll and the fixed scroll, in which the low-pressure chamber sucks the gas to be compressed, and the gas is compressed and discharged from the high-pressure chamber. [0003] During the operation of the scroll compressor, the movable scroll and the fixed scroll move relative to each other. During the compression of the refrigerant, the pressure in each compression chamber is different, resulting in a pressure difference between the refrigerant on both sides of the scroll tooth thickness direction. As a result, the refrigerant easily leaks between the scroll addendum of the fixed scroll and the movable scroll and between the scroll addendum of the movable scroll and the ...
