Abstract

The utility model discloses a vortex type compressor with a reverse rotation preventing device 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 movable disk (4) is inserted in the still disk (5), and a low pressure cavity, a medium pressure cavity and a high pressure cavity are formed between the still disk (5) and the movable disk (4). A high pressure exhaust hole (6) is arranged in the still disk (5) and is connected with an exhaust cavity (7) connected with an exhaust outlet (8). The utility model is characterized in that a reverse rotation preventing device (13) is installed on the end where the bent axle (3) is opposite to the lubricating oil pool (9).

Description

The room air conditioner scroll compressor that has anti-reverse mechanism

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 anti-reverse mechanism.

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.

The structural feature of scroll compressor; its bent axle and rotor are structure as a whole; and for for each moving element of each bent axle provides lubricant oil, the lower end of bent axle must be stretched in the lubricating oil bath, and after motor quits work; must guarantee that bent axle stops operating immediately; can not produce counter-rotating, and existing solution is to increase by two damping vanes in the bent axle lower end, the balance of this structure is relatively poor; cause dead time long, influence the complete machine performance.

Summary of the invention

The purpose of this utility model is that a kind of shutdown of design is rapidly reliable, and the room air conditioner scroll compressor that has anti-reverse mechanism that can not reverse.

The technical solution of the utility model is:

A kind of room air conditioner scroll compressor that has anti-reverse mechanism, 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, on the relative end of its feature bent axle 3 and lubricating oil bath 9 anti-reverse mechanism 13 is installed.

Described anti-reverse mechanism 13 by unilateral bearing 10, counter-rotating stops assembly 11, damping vane 12 is formed, unilateral bearing 10 is fixedly mounted on the bent axle 3, counter-rotating stops assembly 11 and is installed on the unilateral bearing 10, three damping vanes 12 are distributed on counter-rotating and stop on the assembly 11.

The beneficial effects of the utility model:

Simple in structure, manufacturing, easy for installation, good dynamic balance, unilateral bearing can guarantee that it can not produce counter-rotating, three damping vanes have further increased the resistance of bent axle, make shorten greatly dead time.

Fig. 2 is the structural representation of anti-reverse mechanism of the present utility model.

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 anti-reverse mechanism, 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, on the relative end of bent axle 3 and lubricating oil bath 9 anti-reverse mechanism 13 is installed, as shown in Figure 1.Anti-reverse mechanism 13 can be by unilateral bearing 10, counter-rotating stops assembly 11, damping vane 12 is formed, unilateral bearing 10 is fixedly mounted on the bent axle 3, counter-rotating stops assembly 11 (same as the prior art) and is installed on the unilateral bearing 10, and three damping vanes 12 are distributed on counter-rotating and stop on the assembly 11, as shown in Figure 2.

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