Description
Technical field
The present invention relates to techniques of linear motor fields, and in particular to a kind of linear household air-conditioner compressor.
Background technique
Most of household refrigerators compressor generally used uses rotary electromotor driving piston to make reciprocating vibration, must
There must be a set of switching mechanism that the rotary motion of motor is changed into piston linear reciprocating motion.This machine overall volume is huge
Greatly, transmission efficiency is low, noise is big, abrasion is terrible, the service life is short, therefore Piston Refrigerant Compreessor has the potentiality that are greatly improved.
Linear motion is directly generated using electric energy using linear motor, it has the advantages that following prominent:
Structure is simple: in the place that needs move along a straight line, direct-drive may be implemented using linear motor, do not need a set of
Rotary motion is changed into the intermediate conversion mechanism of piston linear reciprocating motion, thus keeps machinery equipment overall structure significantly simple
Change, volume is substantially reduced.
Reaction speed is fast, and trackability is good: linear motor is easily able to brushless contactless operation, and mover has no machine during exercise
Tool resistance, this is the advantages of other traditional drives can not compete.
Reliable and stable, the service life is long: linear motor is a kind of direct drive specific type of electric machine, it can be achieved that non contact transmission power,
Without what mechanical loss, failure is few, hardly needs maintenance, is not afraid of vibration and impact, therefore reliable and stable, the service life is long.
But the input power that the linear motor for being directed to domestic refrigeration system application at present can carry is smaller, and household is empty
Compressor needs kilowatt of adjusting system or more.
Summary of the invention
A kind of linear household air-conditioner compressor proposed by the present invention can solve the straight of existing domestic refrigeration system application
The input power that line motor can carry smaller the technical issues of not being able to satisfy practical application.
To achieve the above object, the invention adopts the following technical scheme:
A kind of linear household air-conditioner compressor, wherein linear drive motor includes stator, mover, interior outer iron core, coil
And cylinder can form multiple flux loops on ring structure iron core using ring structure iron core and star-like mover scheme, and it is star-like
Mover can form multiple air gaps.Two groups of high-performance permanent magnet magnet, and adjacent two are disposed in each air gap
The installation direction of group of magnets is on the contrary, multiple coil serial or parallel connections are on iron core, and the current direction of two adjacent coils begins
Last phase is anti-.When passing to alternating current in coil, mover just generates of reciprocating vibration；
Wherein, cylinder and mover are integrated design, synchronous operation, remain stationary with the piston of cylinder jacket cooperation, pass through pressure
Refrigeration working medium is compressed and is exported into condenser preceding pipeline by the reciprocating motion of contracting cylinder jacket；
Wherein, piston uses hydrostatic gas-lubricated bearing structure, piston outer layer and inner sleeve two parts is specifically included, along piston inner sleeve
Axial end face sets air inlet and valve block mechanism, and gas storage annular groove is reserved between inner sleeve and outer layer, and piston superficies prolong cylindrical surface and set
Two groups of throttle orifices, the annular shallow slot opened up on piston outer layer cylindrical surface perpendicular to piston centreline pass through same group of throttle orifice
It is logical, while throttle orifice is communicated with air reservoir, air reservoir is communicated by air inlet and valve block mechanism with compression chamber, and gas flowing is formed
Path, aerostatic bearing is formd between outer surface of piston and cylinder surfaces；A kind of then straight line household of the invention
Compressor of air conditioner guarantees that moving component is in suspended state by aerostatic bearing without oil lubrication.
As shown from the above technical solution, linear household air-conditioner compressor of the invention includes: stator, mover, iron core and
Coil composition, the ring structure iron core of use and star-like mover scheme can form multiple flux loops on ring structure iron core, and star-like
Mover can form multiple air gaps.Two groups of high-performance permanent magnet magnet, and adjacent two are disposed in each air gap
The installation direction of group of magnets is opposite.Multiple coil serial or parallel connections are on iron core, and the current direction of two adjacent coils begins
Last phase is anti-；In two adjacent air gaps, the direction in magnetic field opposite always is generated, but due to the electricity of two groups of adjacent coils
Flow contrary, therefore magnetic force direction suffered by all magnet is all identical when being powered, and mover is pushed to move toward a direction；Work as line
When passing to alternating current in circle, mover just generates of reciprocating vibration, compresses to refrigeration working medium.
Beneficial effects of the present invention:
One, it may be implemented not contact operation using hydrostatic gas-lubricated bearing supporting structure, piston and cylinder bore, can not add
Add lubricating oil, is conducive to improve domestic air-conditioning system COP；
Two, electric machine structure is compact, and specific volume power is big, and transmission efficiency is high, and low noise is easy to set using axial symmetry type
Count the overall structure of compressor；
Three, high reliablity, linear motor driving piston and cylinder move back and forth relatively, do not need the song of rotating electric machine
Handle link mechanism, does not generate abrasion substantially, and reliability is higher；
Four, the structure of iron core is similar to AC rotary motor, can use the iron core manufacturing method of AC rotary motor.
