Abstract

The utility model discloses a vortex type compressor with a novel lower support structure for room air conditioners, which comprises a machine casing (1), a motor (2) installed in the machine casing (1), a bent axle (3), a movable disk (4) and a still disk (5), wherein the bent axle (3) is sheathed on a rotor of the motor (2), the upper end of the bent axle is connected with the movable disk (4), and the lower end of the bent axle passes through the motor (2) and is opposite to a lubricating oil pool. The utility model is characterized in that a moving apron (10) with an oil sucking bore (13) is arranged at one end where the bent axle (3) is opposite to the lubricating oil pool (9); the lower end of the bent axle (3) and the moving apron (10) are positioned in a lower supporting seat (11); a plane bearing (12) is installed at the inner bottom of the lower supporting seat (11); an oil sucking bore (14) is arranged in the inner bottom of the lower supporting seat; the upper surface of the plane bearing (12) is opposite to the external end surface of the corresponding moving apron (10).

Description

The room air conditioner scroll compressor that has novel lower support structure

Technical field

The utility model relates to a kind of eddy type air condition compressor, especially a kind of room air conditioner scroll compressor that has novel lower support structure.

Background technique

Scroll compressor is very a kind of rapidly idle call compressor of development in recent years, it has the rotating speed height, proper functioning under the deep-fried twisted dough sticks spare can lacked, long service life, easy to maintenance simple, but because its complex structure, difficulty of processing is big, and cost of production is higher relatively and can't be extensive use of in room air conditioner.And constantly perfect along with processing technique in recent years, its cost is more and more lower, so its ratio of using in the particularly high-grade air conditioner of room air conditioner is more and more higher.

As everyone knows, the lower end of the bent axle of scroll compressor is installed in the lower support, it mainly acts on one is to guarantee oil-raising machine oil suction well when making the main shaft axially locating, so require the inner bottom surface and the crankshaft end-face energy good fit of lower support, and the lower end surface of existing bent axle contacts with the inner bottom surface of lower support directly, frictional force is big, quick abrasion, stickiness is not good, must well be solved, with further raising complete machine performance.

Summary of the invention

The purpose of this utility model is that frictional force is little between design a kind of bent axle lower end and the lower support internal surface, fitting has the room air conditioner scroll compressor of novel lower support structure reliably.

The technical solution of the utility model is:

A kind of room air conditioner scroll compressor that has novel lower support structure, comprise casing 1 and be installed in motor 2 in the casing 1, bent axle 3, Moving plate 4, quiet dish 5, bent axle 3 is sleeved on the rotor of motor 2, its upper end links to each other with Moving plate 4, it is relative with lubricating oil bath that motor 2 is passed in its lower end, Moving plate 4 inserts in the quiet dish 5, be formed with low-pressure cavity between quiet dish 5 and the Moving plate 4, middle chamber and the hyperbaric chamber of pressing, have high pressure gas hole 6 on the quiet dish 5, this high pressure gas hole 6 communicates with exhaust cavity 7, exhaust cavity 7 is connected with relief opening 8, it is characterized in that on the relative end of bent axle 3 and lubricating oil bath 9 sideboard 10 that has oil-sucking hole 13 being installed, the lower end of bent axle 3 and sideboard 10 all are arranged in undersetting 11, inner bottom part at undersetting 11 is equipped with plane bearing 12, and being provided with oil-sucking hole 14, the upper surface of plane bearing 12 is relative with the exterior edge face of corresponding sideboard 10.

The beneficial effects of the utility model:

Simple in structure, manufacturing, easy for installation, it is little to wear and tear, and oil suction is reliable, and during axial float, sideboard 10 contacts with plane bearing 12, thereby rotational resistance is little.

Embodiment

Below in conjunction with drawings and Examples the utility model is further described.

As shown in Figure 1, 2.

A kind of room air conditioner scroll compressor that has novel lower support structure, comprise casing 1 and be installed in motor 2 in the casing 1, bent axle 3, Moving plate 4, quiet dish 5, bent axle 3 is sleeved on the rotor of motor 2, its upper end links to each other with Moving plate 4, it is relative with lubricating oil bath that motor 2 is passed in its lower end, Moving plate 4 inserts in the quiet dish 5, be formed with low-pressure cavity between quiet dish 5 and the Moving plate 4, middle chamber and the hyperbaric chamber of pressing, have high pressure gas hole 6 on the quiet dish 5, this high pressure gas hole 6 communicates with exhaust cavity 7, exhaust cavity 7 is connected with relief opening 8, as shown in Figure 1, on the relative end of bent axle 3 and lubricating oil bath 9, the sideboard 10 that has oil-sucking hole 13 is installed, the lower end of bent axle 3 and sideboard 10 all are arranged in undersetting 11, at the inner bottom part of undersetting 11 plane bearing 12 are installed, and are provided with oil-sucking hole 14, the upper surface of plane bearing 12 is relative with the exterior edge face of corresponding sideboard 10, as shown in Figure 2.

It is all same as the prior art that present embodiment does not relate to part.
