Abstract

The utility model relates to an accumulator of compressor of air conditioner, which comprises a shell and a discharge pipe, wherein the discharge pipe is composed of welded inner straight pipe and outer bent pipe which are made detachably, the upper half portion of the inner straight tube is arranged with a noise reducer which thickness ratio with the shell is 0.2-1.1, the outer edge of the noise reducer is fixed with the inner wall of the shell, while the inner edge is fixed with the outer wall of the inner straight tube, the outer and inner edges are provided with a through hole between. The utility model arranges a noise reducer to fix the inner tube, based on prior three-sector accumulators which use iron or iron alloy tube as inner tube, to reduce the vibration of inner tube and reduce noise, to eliminate the resonance noise of the inner tube with low cost, to reduce 2-3dB noise of the compressor.

Description

A kind of cooler compressor reservoir

Technical field

The present invention relates to the air-conditioner field, particularly the cooler compressor reservoir.

Background technology

Existing compressor liquid storage device comprises air inlet pipe, loam cake, housing, blast pipe, dividing plate, lower cover, and the net-filter assembly of being made up of filter screen, filter screen pressure ring, backing plate.One end of air inlet pipe is arranged on the outside, upper end of loam cake, and the other end is arranged on the inside, lower end of loam cake, and loam cake extends out, and is placed in the top of housing; Net-filter assembly is arranged on enclosure interior, and with carry out the tracheae adjacency; Contract in the lower cover, be placed in the bottom of housing, between adopt the stove weldering to connect; Blast pipe comprises straight tube and bend pipe two parts, blast pipe can be made into integration by copper pipe, for reducing material cost, also can be separately made, straight tube as interior tube portion adopts iron pipe to make, bend pipe as outer tube part adopts copper pipe to make, and stretch out outside the lower cover straight-tube portion lower end that is positioned at housing, is connected with adopting the stove weldering between bend pipe, the lower cover.But, though split type blast pipe has reduced cost, but following problem has appearred: because the interior pipe of reservoir adopts iron pipe, and the rigidity of iron pipe is bigger, density is smaller, and is unfixing again, when particularly interior pipe is longer, in case compressor operating just is easy to produce resonance, noise can increase.

Summary of the invention

For addressing the above problem, the purpose of this utility model provides a kind of cooler compressor reservoir, and its cost is low, and noise is less simultaneously.

The purpose of this utility model is achieved in that a kind of cooler compressor reservoir, comprise housing, blast pipe, wherein blast pipe is welded by the interior straight tube that is separately made and outer bend pipe two parts, it is characterized in that: the first half position of straight tube is provided with thickness with housing than the noise reduction parts that are 0.2～1.1 in described, this noise reduction parts outer rim and reservoir inner walls are fixed, noise reduction parts inner edge and interior straight tube outer wall are fixed, and are provided with through hole between outer rim and the inner edge.

The installation site of described noise reduction parts is in the scope of interior straight tube suction end straight tube 1/2nd length in down 5mm rises to this.

The utility model is on the basis of triplasy reservoir of interior straight tube adopting at present iron pipe or ferroalloy pipe, fix interior pipe by adding noise reduction parts, the vibrations of pipe reduce in making, from to reduce noise, guaranteeing cheaply simultaneously, the noise that pipe resonance causes in eliminating makes compressor noise decline at least 2～3dB.

The specific embodiment

Below in conjunction with drawings and Examples, the utility model is done detailed explanation.

Be illustrated in figure 2 as the triplasy reservoir, comprise air inlet pipe 1, loam cake 2, housing 5, blast pipe (being fixed into), noise reduction parts 9, lower cover 8 and net-filter assembly (forming) by filter screen 3, filter screen pressure ring and backing plate 4 by iron or ferroalloy interior straight tube of making 6 and outer bend pipe 7 welding that are made of copper.

Institute is shown in Figure 3, noise reduction parts 9 are circular, through a large amount of experimental demonstrations, integrated cost reduces the noise target with realization, the ratio of noise reduction component thickness and thickness of shell is can meet the demands between 0.2～1.1, even continue to strengthen the thickness ratio, noise reduction also no longer includes more obvious raising, but also increases the difficulty of cost and processing.In the present embodiment, the noise reduction component thickness is 1 with the ratio of thickness of shell.The outer rim 92 of noise reduction parts 9 and inner edge 93 upwards are bent to form sidewall (also can be bent to form sidewall downwards), its outer rim 92 diameters are identical with housing 5 internal diameters, fixing with the welding of reservoir housing 5 inwalls, inner edge 93 diameters are identical with interior straight tube 6 external diameters, and are fixing with interior straight tube 6 outer walls welding.In noise reduction parts 9 outer rims 92 welding annular groove 91 can be set also, hold the red copper scolder when being used to weld.In addition, the bending position of noise reduction parts 9 inner edges 93 is chamfering structure, can hold the red copper scolder equally when welding.During assembling, earlier interior straight tube 6 is filled to and requires position (certain position of interior straight tube 6 tightens is furnished with red copper weld-ring 61), again noise reduction parts 9 are pressed into (the red copper weld-ring of packing in advance in the welding annular groove 91 of noise reduction parts 9), noise reduction parts 9 are in the process that is pressed into, red copper weld-ring 61 in noise reduction parts 9 madial walls bending position promotes on the straight tube 6 is depressed into together and requires the position, treat the reservoir assembling finish after through the stove weldering realize noise reduction parts 9 and housing 5 and in straight tube 6 be welded into one.Adopt the weldering of red copper solder pot to be connected equally between interior straight tube 6 and outer bend pipe 7, the lower cover 8.

For reaching best noise reduction, the position of the straight tube first half in strengthening part 9 should be arranged at, straight tube all has fixing point in two ends up and down in making, and eliminates vibration.Best, strengthening part 9 is installed in from straight iron tube 6 upper end suction ends down between position to the position of interior straight tube total length 50% of 5mm, and promptly the length range of L-1 is 5mm～1/2L as shown in Figure 2, can eliminate interior pipe resonance preferably.

In order not influence liquid refrigerants, should between its outer rim 92 and inner edge 93, offer some through holes 94 on the basis that does not influence its fixed effect during design by noise reduction parts 9.
