Description
Technical field
This practicality is related to a kind of compressor, more particularly to a kind of compressor with novel isolating structure.
Background technology
Compressor refers to a kind of driven fluid machinery that low-pressure gas is promoted to gases at high pressure, is the heart of refrigeration system
Dirty, it is operated after being compressed with piston to it, to row from the refrigerant gas of air intake duct suction low-temp low-pressure by motor
Tracheae discharges the refrigerant gas of high temperature and pressure, power is provided for kind of refrigeration cycle, so as to fulfill compression → condensation（Heat release）→ swollen
Swollen → evaporation（Heat absorption）Kind of refrigeration cycle.Compressor can be divided into piston compressor, helical-lobe compressor, centrifugal compressor and straight line pressure
Contracting machine etc., by taking piston compressor as an example, piston compressor is generally by housing, motor, cylinder body, piston, control device（Starter
And thermal protector）And cooling system composition, cooling is mainly realized by oil cooling and air-cooled two ways.
Current compressor uses motor direct-drive substantially, and motor is directly encapsulated into inside compressor, and motor
Cooling is also the low temperature refrigerant by being sucked in compressor（Containing refrigerator oil）To carry out cooling down, with regard to current compressor arrangement
In form, motor is directly directly to be contacted with low temperature refrigerant or refrigerator oil, because refrigerant is gaseous state when entering compressor, together
When refrigeration oil be also insulation, therefore under normal circumstances, the drain conditions of motor will not be caused.But operated under specific operation
When, refrigerant can be rendered as liquid form or when water leaking-in timesharing in compressor, refrigerator oil can also lose insulating properties.The above two
Kind situation all will result directly in motor electric leakage phenomenon, and double threat is caused to the normal operation and personal safety of product.
Based on the above-mentioned motor electric leakage risk being likely to occur, can only rely at present to the preferable enameled wire of electric wire over cladding process
To prevent motor electric leakage phenomenon, and a large amount of seals are filled to put the axe in the helve in junction.But the enamelled coating of existing enameled wire
Manufacture craft is not ensured that on enameled wire without white point（It is not coated with the local dot of japanning）, and white point is to cause compressor to lose absolutely
The factor of edge, furthermore, too many due to being tightly connected point, any one link may cause leakage point, be unfavorable for dropping on the contrary
Low drain risk, in addition, the manufacture cost of insulation for compressor and process costs are all very high so that the price of product is more
Costliness, is unfavorable for market competition.
Therefore, for disadvantages described above, it is necessary to effectively be innovated to the prior art.
Utility model content
For disadvantages described above, this practicality provides a kind of compressor with novel isolating structure, and motor is positioned over one
In individual cavity so that low temperature refrigerant or refrigerator oil are no longer by the outgoing line position of electric machine assembly and electric machine assembly, from root
Solve the risk of motor electric leakage in sheet, while by varying the arrangement mode of electric machine assembly, allow low temperature refrigerant or refrigerator oil
From motor individual cavity periphery by having achieveed the purpose that to cool down electric machine assembly.
Compressor described in this practicality is traditional electric scroll compressor, including rack, air inlet, driver, stator,
Rotor, drive shaft, bearing, axle envelope, seal, fixed scroll, movable orbiting scroll, whirlpool disk bearing support, the eccentric adjustable mechanism, anti-of movable orbiting scroll
The basic building blocks such as rotation mechanism, gas outlet, in view of above structure is all ripe technology, therefore, this practicality is to the specific of compressor
Structure no longer detail describes, and needs selected parts part-structure explanation with regard to technology description.
This practicality specifically uses following technical scheme：
A kind of compressor with novel isolating structure, including rack, structure for conveying, motor cavity and air cavity, in rack
Portion sets three great institutions of structure for conveying, motor cavity and air cavity, and structure for conveying is used for transporting low temperature refrigerant or refrigerator oil, motor cavity
It is built-up by cylinder body, it is used to accommodate electric machine assembly, including driver, stator, rotor and driving shaft component, gas in motor cavity
Intracavitary sets whirlpool disk component, including movable orbiting scroll, fixed scroll and bearing support, and the same structure for conveying of motor cavity, air cavity carry out independent isolating
Set；
Correspondingly, structure for conveying may be configured as annular, to make refrigerant or machine oil fully be looped around motor cavity outer wall with cold
But electric machine assembly；
Correspondingly, motor cavity may be configured as one, one motor cavity of setting, because of driver and remaining electric machine assembly sheet
Body is in together in a motor cavity, and the motor cavity has carried out individual cavity setting, and therefore, the electrical connection between electric machine assembly need not
Isolation encapsulation process additionally is carried out to refrigerant and machine oil again；
Correspondingly, motor cavity may be configured as two, when being provided with two motor cavities, driver can be separately positioned to one
In cavity, the same cylinder body of seal is utilized（Motor where the cylinder body cylinder body and remaining electric machine assembly of motor cavity where driver
The cylinder body of chamber）It is connected and sealed, i.e., two motor cavities is connected by seal so that electric wire is not present with refrigerant or machine oil and connects
Touch；
Correspondingly, seal is hollow structure, exist in seal with the mounting hole that cylinder body is fixed with hollow space
Certain interval, the interval can prevent refrigerant or machine oil from being leaked from mounting hole into the hollow space or even motor cavity of seal,
Sealing device can be also added on the mounting hole of seal, further improves leakproofness；
Correspondingly, cylinder body is both provided with sealing device with bearing support and shaft with the junction of bearing support；
Correspondingly, the transfer passage of connection structure for conveying is provided with bearing support so that refrigerant or machine oil are able to by defeated
Passage is sent to enter air cavity to realize compression and discharge, which can set one or more.
This practicality has the beneficial effect that：
First, electric machine assembly is positioned in an individual cavity so that low temperature refrigerant or refrigerator oil no longer pass through motor
The outgoing line position of component and electric machine assembly, fundamentally solves the risk of motor electric leakage；
2nd, reduce and required for the demand of seal and manufacture, saving raw material input and production cost
Improve the competitiveness of product in market at the same time；
3rd, nor affected on for the electrical connection between electric machine assembly even with common enameled wire between motor and refrigerant, machine oil
Isolation；
4th, new arrangement has been carried out to electric machine assembly internal structure, has made refrigerant or machine oil logical from motor individual cavity periphery
Cross, achieveed the purpose that to cool down electric machine assembly.
