Abstract

The present invention relates to an L-shaped pipe fixing structure of a closed rotary compressor. A bracket is fixed to the side surface of a closed machine shell, and an L-shaped pipe fixing structure of a belt-shaped object having both ends fixed to the bracket and a center integrated with fixed parts for fixing an L-shaped pipe is arranged outside the bracket; a pair of fixed parts is formed in the center of the belt-shaped object in a punching way, and shock absorbing rubber for buffering vibration is inserted between the L-shaped pipe and the fixed parts. Thus, the number of parts for fixing the L-shaped pipe is reduced, and simultaneously, mounting procedures are reduced. Moreover, the shock absorbing rubber inserted between the L-shaped pipe and the fixed parts can reduce friction noise generated during the operation of the compressor.

Description

The L type pipe fixation structure of closed rotary compressor

Technical field

The present invention relates to compressor field.

Background technique

The invention relates to closed rotary compressor, particularly about utilizing the L type pipe of simple structure fixing seal casing side, thus can be at the L pipe fixation structure that reduces the closed rotary compressor that part number reduces production costs thus.

Below, see figures.1.and.2, the closed rotary compressor that uses in the refrigeration cycle compressed refrigerant that is used for household electric appliance such as air-conditioning is described.

As shown in the figure, existing closed rotary compressor is provided with the liquid-storage container 2 of separating liquid refrigeration agent in sealed enclosure 1 side of the part that various compressed refrigerants are set, and utilize L type pipe to connect the lower end of liquid-storage container 2 and the side of sealed enclosure 1, so that the gaseous refrigerant that separates on liquid-storage container 2 flows into sealed enclosure 1 inside.

And, L type pipe 3 utilization be fixed on the fixing support in sealed enclosure 1 side 4 and central authorities form the L type pipe carrier 5 of the 5a of support part that supports L type pipe inner side surface and surround the ribbon 6 of L type pipe and bolt 7 that ribbon 6 and L type pipe carrier 5 one ends are fixed on the support 4 fixing.

When possessing the existing closed rotary compressor fixed L type pipe of said structure, on the support outside that L type pipe carrier is positioned at be welded on sealed enclosure 1 side.Then, the inner side surface of L type pipe 3 is placed on the assembly department 5a of L type pipe carrier 5 central authorities formation, when utilizing ribbon 6 to support the L type pipe outside one end of L type pipe is fixed at an end of support 4 with L type pipe carrier 5 framves, and the other end utilizes bolt 7 to be fixed on the other end of support 4 with L type pipe carrier 5.

But above-mentioned existing closed rotary compressor fixed structure utilizes numerous parts to fix L type pipe 3, can't reduce manufacture cost thus and can't reduce installation procedure.

And when utilizing a plurality of metal partss to support L type pipe, the vibrations during compressor operating can cause friction noise.

Summary of the invention

Technical problem to be solved by this invention is, a kind of L type pipe fixation structure of closed rotary compressor is provided, reduce the part number of fixed L type pipe, thereby reduce installation procedure when reducing manufacture cost, and reduce friction noise between the part of L type pipe and fixed L type pipe.

In order to solve the problems of the technologies described above, the technical solution used in the present invention is: the L type pipe fixation structure of closed rotary compressor, the side that is included in sealed enclosure is provided with the L type pipe of the side of liquid-storage container, the lower end that connects liquid-storage container and sealed enclosure, support has been fixed in side at sealed enclosure, be fixed on the support and in the outside of support two ends have been installed, the fixing part of central authorities and fixed L type pipe forms the ribbon of one.

The L type pipe fixation structure of described closed rotary compressor has formed a pair of fixing part that can be out of shape that punching press forms in ribbon central authorities.

The L type pipe fixation structure of described closed rotary compressor, the insulation rubber of insertion damping vibration between L type pipe and fixing part.

The invention has the beneficial effects as follows: the closed rotary compressor of the present invention's design has been fixed support on the outer cylinder of sealed enclosure, and in the outside of support the ribbon that forms one with the fixing part of fixed L type pipe has been installed.Thereby when fixed L type pipe, on the support of the side of sealed enclosure, in conjunction with having fixed ribbon, and utilize the simple fixed L type of the fixing part that forms on ribbon pipe.In the part number that reduces fixed L type pipe, reduced installation procedure thus.And, between L type pipe and fixing part, insert insulation rubber, the friction noise that has produced when having reduced compressor operating thus.

Embodiment

Below in conjunction with the drawings and specific embodiments the present invention is described in further detail: Fig. 3 represents to possess the closed rotary compressor stereogram of the L type pipe fixation structure in one embodiment of the present of invention, the plan view of Fig. 4 presentation graphs 3.

As seen from the figure, be provided with the liquid-storage container 2 of separating liquid refrigeration agent in sealed enclosure 1 side of the part that various compressed refrigerants are set, and utilize L type pipe 3 to connect the lower end of liquid-storage container 2 and the side of sealed enclosure 1, so that the gaseous refrigerant that separates on liquid-storage container 2 flows into sealed enclosure 1 inboard.

And, on the outer side surface of sealed enclosure 1, fixed horseshoe-shaped support 111, and at the fixing part 112 and "〉of the central fixed L type pipe of support 111 " ribbon 113 of type forms one, and end frame the other end 113b under the state of support 111 1 end 111a of ribbon 113a utilizes bolt 114 to be fixed on the other end 111b of support 111.

Fig. 5 represents the stereogram of ribbon 113, and as shown in the figure, ribbon 113 is the sheet metals with certain area, one end 113a bending, and the other end 113b has formed bolt hole 113b`, has formed a pair of fixing part 112 that can be out of shape that punching press forms in the central authorities.

In the closed rotary compressor of the present invention's design that as above constitutes, adopt the method for welding that support 111 is fixed on the outer side surface of sealed enclosure 1 when fixing 1 type pipe.

Then, make L type pipe be positioned at the outside of support 111, ribbon 113 is set makes it support the outer side surface of L type pipe.At this moment, an end frame that makes ribbon 113a is at support 111 1 end 111a, and the other end 113b utilizes bolt 114 to be fixed on the other end 111b of support 111.

Then,, make it wrap L type pipe 3 with fixing part 112 bending deflection to the inside of punch process on the ribbon 113, thus fixed L type pipe 3 simply.And because retaining element quantity seldom, so the friction noise between the part also can reduce.

Fig. 6 represents the plan view of an alternative embodiment of the invention, and as shown in the figure, the formation of the embodiment among the formation of fixed L type pipe 3 parts and Fig. 3 and Fig. 4 is identical, omits its explanation here.

Discrepancy is at the outer cylinder that utilizes the fixing L type pipe 3 of ribbon 113, that is, inserted in the inboard of the fixing part 112 of ribbon 113 can damping vibration insulation rubber 200.When compressor operating, the vibrations of generation are cushioned by insulation rubber 200, thereby have reduced friction noise.
