Problems solved by technology
[0007] However, in the overvoltage state at the start of the compressor, a large torque exceeding the required value is suddenly applied to the load, so the oil equalizing pipe may receive excessive impact
In the prior art, under the above-mentioned high voltage, a large torque exceeding the required value is generated, so when an excessive shock is transmitted to the oil equalizing pipe, there is a problem that the reliability of the oil equalizing pipe is broken, etc.
[0008] In particular, if the oil equalizing valve, which is connected to the oil equalizing pipe and suspended in the space, is impacted and vibrates without being supported by an additional component, the durability of the oil equalizing pipe will decrease.

[0040] In the first embodiment, an outdoor unit having three compressors was described as an example, but the present invention includes an outdoor unit having an arbitrary number of compressors of two or more.
[0041] Inside each compressor 20, in order to lubricate and cool each driving part (not shown) inside the compressor 20, the bottom of the compressor 20 holds oil, and in order to make this oil evenly distributed to a plurality of compressors 20, compress The lower part of the machine 20 has an oil equalizing device 50 .
[0042] The oil equalizing device 50 includes: a plurality of oil equalizing pipes 51 communicated with the bottom of the compressor 20 for discharging excess oil supplied to the compressor 20; an oil equalizing valve 52 arranged in the pipeline of the oil equalizing pipe 51 for The oil equalizing pipe 51 is opened according to the oil level of the engine oil to discharge the engine oil from the compressor 20 .
[0043] For the oil equalizing device...

The present invention discloses an outdoor unit of air conditioner which can also ensure the reliability of the apparatus for uniforming oil level even if the compressor starts up at overvoltage. The outdoor unit of air conditioner according to the invention includes: a plurality of compressors connected to at least one refrigerant pipe; an oil level uniforming pipe connected to the plurality of compressors, for uniforming and maintaining the engine oil of the plurality of compressors; at least one oil level uniforming valve arranged in the pipeline of the oil level uniforming pipe; and a foxing memeber for fixing the oil level uniforming valve to the at least one refrigerant pipe.
Description
technical field [0001] The present invention relates to an air conditioner, and more particularly to an air conditioner including a fixing member for preventing damage to an oil equalizing pipe provided between a plurality of compressors for uniformly maintaining lubricating oil. Background technique [0002] Generally, an air conditioner is a device that performs air conditioning based on heat absorbed or released during a refrigeration cycle of compression, condensation, expansion, and evaporation of refrigerant. The compressor that compresses the refrigerant in this air conditioner is one of the core devices, but due to the high pressure and temperature, the friction is relatively serious and it is easy to be damaged. [0003] In order to ensure the reliability of the operation of the compressor, it is particularly important to perform lubrication or cooling, and the lubricating and cooling is carried out by machine oil, so the compressor needs to keep a certain amount of...
