Description
Technical field
The utility model is related to a kind of compressor, specifically a kind of rotary compressor.
Background technology
Energy-conservation and environmental protection are the two principal themes of current refrigeration, air conditioner industry.Compressor is most important portion in refrigeration system
Part, the materials'use amount for reducing compressor is also the important measure of energy-conservation.Therefore compressor miniaturization is also the trend of its development.
Want to realize compressor miniaturization, it is necessary to carry out the exploitation of big capacity in small shell footpath.Compressor air-discharging amount is V
=π (Dcy2-Dro2) H/4, wherein Dcy is cylinder bore diameter, and Dro is piston external diameter, and H highly, will increase the row of compressor for cylinder
Tolerance, in the range of rational ratio of height to diameter, certainly will will increase cylinder bore diameter and cylinder highly.The increase of capacity also implies that pressure
The increase of contracting acc power.
High-power required by big capacity in order to reach, rotor can be by increasing the side of height Hs or outer diameter D s
Method is realized, but increases of height can cause the increase of bent axle major axis deflection, influence compressor reliability, while the height of rotor
Will also by compressor it is total it is high limited, on the other hand due to the limitation of shell footpath Dc, outer diameter D s is excessive and can cause motor stator
Difficult design.There is presently no the redesign that a kind of simple, easy-to-use method carries out motor, therefore, the problem of capacity
Optimum level is not reached always.
Utility model content
Not enough in order to make up the above, the utility model provides one kind and increases exhaust in the case where cylinder height is not changed
The rotary compressor of amount, with solving the problems, such as above-mentioned background technology.
Rotary compressor of the present utility model, including housing and the compressor inner core in housing, the compression
Machine inner core includes bent axle, the rotor being sleeved on outside bent axle major axis, and the eccentric part of the bent axle is located at cylinder interior, the gas
Piston is set in cylinder, and the piston is set in the eccentric part of bent axle, and the rotor external diameter is with the ratio of cylinder bore diameter
1.14≤Ds/Dcy≤1.411。
By adopting the above-described technical solution, rotary compressor described in the utility model is by changing outside rotor
Footpath and the ratio of cylinder bore diameter, increase capacity in the case of compressor arrangement is rational, improve the service efficiency of compressor.
Brief description of the drawings
In order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art, below will be to embodiment
Or the accompanying drawing to be used needed for description of the prior art is briefly described, it should be apparent that, drawings in the following description are only
It is some embodiments of the present utility model, for those of ordinary skill in the art, before creative labor is not paid
Put, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the utility model embodiment.
Specific embodiment
Embodiment one：As shown in figure 1, rotary compressor described in the utility model, including housing 1 and installed in housing
Compressor inner core in 1, the housing 1 has an openable cap, and the cap interference fit is installed on housing 1,
The compressor inner core is arranged in the inner chamber of housing 1.
The compressor inner core includes bent axle 2, the rotor 3 that is sleeved on outside the major axis of bent axle 2, the rotor 3 with
Motor stator 4 is engaged setting, and the bent axle 2 is set along the length direction of housing 1, and bent axle 2 is arranged in the inner chamber of housing 1
Portion, the eccentric part of the bent axle 2 is arranged in cylinder 6, and cylinder 6 is including in the cylinder under upper cylinder cover between cylinder cap and two cylinder caps
Piston 5 is installed at chamber, the middle part of the cylinder 6, and piston 5 is moveably mounted to the inner side of cylinder 6, and the piston is set in bent axle 2
Eccentric part, moved with piston 5 by bent axle 2, the ratio of the external diameter of the rotor 3 and the internal diameter of cylinder 6 is 1.14≤Ds/
Dcy≤1.411, compressor air-discharging amount is V=π (Dcy2-Dro2) H/4, wherein Dcy is cylinder bore diameter, and Dro is piston external diameter, H
For cylinder highly, the stability of bent axle is highly influenceed due to changing cylinder, therefore, increase in the case where cylinder height is not changed
Cylinder bore diameter or reduce piston external diameter can play a part of increase capacity, in existing compressor design, rotor diameter with
The ratio of cylinder bore diameter is general in Dc/Dcy≤1.14, and this design causes that cylinder influences external diameter of cylinder in global design
Size, it is impossible to reach and increase capacity to greatest extent, the external diameter of rotor 3 and the internal diameter of cylinder 6 are shown by substantial amounts of experiment
Ratio be 1.14≤Ds/Dcy≤1.411 when, compressor performance stabilization in the case of, external diameter of cylinder and capacity reach most
Big value, the power of compressor also reaches maximum.
General principle of the present utility model, principal character and advantage of the present utility model has been shown and described above.One's own profession
The technical staff of industry it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Simply illustrate principle of the present utility model, on the premise of the utility model spirit and scope are not departed from, the utility model is also
Various changes and modifications are had, these changes and improvements are both fallen within the range of claimed the utility model.The utility model
Claimed scope is by appending claims and its equivalent thereof.
