Abstract
The utility model relates to a totally-enclosed four-rotary system refrigeration compressor used for the technical field of refrigeration and air conditioners, which comprises a totally-enclosed machine casing. A fixing seat is arranged at the lower part of the machine casing; the outer surface of the machine casing is also provided with a power supply binding post, an air inlet, and an air outlet; a crankshaft in the machine casing is orderly provided with a motor stator coil, a motor rotor, an upper end cover, a piston cylinder, a cylinder shell, a piston, and a lower end cover from top to bottom. The lower end of the lower end cover is provided with a tower-shaped support spring; a piston hole is arranged on the piston cylinder; the piston is arranged in the piston hole; the cross section of the piston can be of a rectangle shape or a circle shape. Due to the adoption of a four-rotary system, the utility model has the advantages of high efficiency, energy saving, simple structure, and low cost.
Description
The utility model relates to a kind of invention that is used for the totally-enclosed four revolution refrigeration compressors of freezing and air-conditioning technical field.
Compressor all must be used in refrigerating equipment inside such as existing refrigerator, refrigerator and air conditioner, and the structure of these compressors has rotary type and piston type, and they respectively have its characteristics, and wherein the rotary type advantage is that efficient height, part are few.Shortcoming is the machining accuracy height, and refrigerating capacity is little; Advantage in the form of piston then is a technical maturity, and refrigerating capacity is big; But it is low also to exist efficient, the big shortcoming of noise.
The purpose of this utility model is: provide a kind of compatibility that the totally-enclosed four revolution refrigeration compressors of rotary type and piston compressor advantage are arranged.
The contract feature of its structure of machine of the described totally-enclosed four revolution refrigeration of the utility model is: it comprises a totally enclosed casing, and the casing bottom is provided with a fixed base, also is provided with power-line terminal, suction port and relief opening on the casing outer surface; Then be provided with coil of stator of motor, rotor, upper end cap, piston cylinder, cylinder shell, piston and lower end cap from top to bottom successively on the vertical bent axle of placing in the casing.Wherein the lower end cap lower end is provided with a turriform supported spring; Be shaped on piston hole on the piston cylinder, be provided with piston in the piston hole.
The cross section of the piston in the above-mentioned piston hole of the utility model can be rectangle or circle.
The utility model is owing to adopted above-mentioned new structure, and bent axle and motor are coaxial, the crank on the bent axle drive piston at the uniform velocity revolve round the sun with rotation in, piston cylinder and bent axle are also done uniform rotation, thereby have constituted four revolution systems.Thereby energy-efficient, and the utility model part is few, and is simple in structure, easy processing, cost are low; Capacity is big, noise is low.
Description of drawings the utility model embodiment's structure:
Fig. 1 is the sectional view of the utility model agent structure.
In accompanying drawing 1, the utility model general structure is contained by a totally enclosed casing 11, casing 11 by the sheet metal punching press after, be welded relatively, the outer surface of casing 11 only is provided with ABAP Adapter wiring terminal 13, suction port 3 and relief opening 12, and the bottom of casing 11 is provided with a fixed base that is used to install 14.In casing 11, be respectively equipped with coil of stator of motor 2 from top to bottom successively, rotor 1, upper end cap 5, piston cylinder 6, cylinder shell 7, piston 8 and lower end cap 9 on the vertical bent axle of placing 4.The lower end cap bottom is provided with a turriform supported spring 10, in order to all parts in the support machine casing 11.Wherein be provided with piston 8 in the piston cylinder 6; Rectangle both can have been made in the cross section of piston 8 also can make circle.The upper end fixed electrical machinery rotor of bent axle 4, following overhung crank driven plunger 8 and piston cylinder 6 rotate; That is to say that piston 8 has revolution and rotation simultaneously, and piston cylinder 6 and bent axle 4 also do at the uniform velocity rotation motion, so just constituting four revolution systems, improving the working efficiency of compressor widely.
