Abstract

A filter of an air conditioner comprises a shell (2) cast into a whole and two interfaces (1) (3) which are arranged at two ends of the shell (2). The shell internally comprises a filter screen (21) which is a bag-shaped structure which can be fixed; the bottom of the filter screen (21) is extended into the interior of the shell. As the filter screen is the bag-shaped structure, the filter of the air conditioner of the utility model can contain impurity quantity which is far more than the impurity containing quantity of flat-shaped filter screen; the refrigerant fluid can smoothly pass through the side part of the filter screen; when the refrigerant fluid changes the direction to flow along the reversed arrowhead direction, the refrigerant fluid can pass through the side part of the filter screen; the deposited impurity in the fluid gathers close to the end of the filter screen, does not affect the flow speed and flux of the refrigerant and can meet the bidirectional flow of the refrigerant fluid.

Description

Air conditioner filters

Technical field

The utility model relates to a kind of air conditioner filters that is used for, and relates in particular to a kind of filtering silencer that is used for the air-conditioner hose system.

Background technology

In air-conditioner inside, refrigerant fluid flows in the pipe-line system of sealing, carries out kind of refrigeration cycle.Behind the air-conditioner long-play, can have many impurity in the refrigerant fluid, the generation of impurity former because: in the production installation process of air-conditioner, the weldering bits that welding produces during copper pipe; When refrigerant fluid was flowed through compressor, each parts of compressor also produced impurity.Impurity is sneaked in the refrigerant fluid, as not filtering, will produce following influence to air-conditioner: stop up capillary, burn out compressor, reduce the heat exchange effect of heat exchanger.Therefore, people install filter usually in the air-conditioner hose system, in order to filter the impurity in the refrigerant fluid.Filter commonly used adopts following structure: the interface that comprises housing and two ends thereof is formed, housing and interface are tubular structure, the radius of housing is provided with the screen pack of a slice disc greater than the radius of interface in housing, the radius of screen pack and the inside radius of housing are about equally.When refrigerant fluid was flowed through the screen pack of housing by interface, impurity was filtered.Adopt the above-mentioned filter that the screen pack of disc is set, following defective is arranged: 1, the filtrable impurity level of screen pack is very limited, and air-conditioner is after the operation long period, and screen pack is covered by impurity fully, influences the flow of refrigerant fluid; 2, refrigerant fluid can only unidirectionally pass through, and for heat pump type air conditioner, refrigerant fluid needs two-way flow, and then this kind filter can't use; 3, refrigerant fluid sends the jet sound of " giving a tongue-lashing " in the process middle filtrator housing of the filter of flowing through, and increases the noise of air-conditioner, destroys the tonequality of air-conditioner.

Summary of the invention

The purpose of this utility model is exactly in order to overcome above-mentioned defective, a kind of air conditioner filters is provided, but the refrigerant fluid two-way flow, and air-conditioner is after the operation long period, impurity in the refrigerant fluid can not stop up screen pack, does not influence the flow of refrigerant fluid.

The utility model provides a kind of air conditioner filters, comprises housing cast in block and two interfaces that are positioned at its two ends, also comprises screen pack in the described housing, and described screen pack is the fixable sack shape of a shape structure, and extend to enclosure interior the bottom.

Adopt air conditioner filters of the present utility model, because screen pack is a sack shape structure, the impurity level that can hold is much larger than the impurity saturation of plain film shape screen pack, behind the air-conditioner long-play, impurity in the fluid that deposits still accumulates near the bottom of screen pack, refrigerant fluid still can be successfully passes through from the sidepiece of screen pack, when the refrigerant fluid commutation is mobile along the arrow rightabout, refrigerant fluid can pass through from the sidepiece of screen pack, accumulation of impurities in the fluid that deposits is near the end of screen pack, can not influence the flow velocity and the flow of cold-producing medium, and can satisfy the two-way flow of refrigerant fluid.

The specific embodiment

Embodiment one:

Shown in Figure 1, the utility model provides a kind of air conditioner filters, described filter comprises interface 1 cast in block, housing 2 and interface 3, described housing 2 links to each other with interface 3, described interface 3 can comprise one or more through holes as required, among the embodiment one, described housing 2 is round tube shape structure with interface 3 and endoporus links to each other, and the inside and outside radius of housing 2 is greater than the inside and outside radius of interface 3; Described interface 1 connects the other end of housing 2, also comprises one or more through holes that are connected with the housing endoporus.The support 22 that also comprises screen pack 21 and spiral spring structure in the described housing 2, described support 22 can also be the steelframe of other structures, described screen pack 21 is the sack shape structure of opening to interface 3, its opening is positioned near the interface 3, the bottom of sack is to housing 2 inner extensions, and described screen pack 21 can adopt the wire material.Described support 22 is positioned at screen pack 21 inside, is used for tensioning and fixing screen pack 21.

When refrigerant fluid as shown in Figure 1 along the direction of arrow by interface 3 screen pack 21 of flowing through, during from interface 1 outflow, impurity is filtered that net 21 stops and 211 places, bottom that are deposited on screen pack 21 in the fluid, because screen pack 21 is a sack shape structure, the impurity level that can hold is much larger than the impurity saturation of plain film shape screen pack, behind the air-conditioner long-play, impurity in the fluid that deposits still accumulates near the bottom 211 of screen pack 21, refrigerant fluid still can be successfully passes through from the sidepiece 212 of screen pack 21, can not influence the flow velocity and the flow of cold-producing medium.When the refrigerant fluid commutation is mobile along the arrow rightabout, because 22 pairs of screen packs 21 of support play tensioning and fixation, refrigerant fluid can pass through from the sidepiece 212 of screen pack 21, and the accumulation of impurities in the fluid that deposits is near the end 213 of screen pack 21.Simultaneously, described interface 1 can comprise a plurality of through holes that are connected with the housing endoporus, and filter of the present utility model also plays the effect of separatory.

Embodiment two:

Shown in Figure 2, embodiment two of the present utility model is with embodiment one difference: in the inside of screen pack 21, also be provided with particulate material, described particulate material is full of screen pack (21), described particulate material can be several plastic beads 23, at the openend of screen pack 21, be provided with sequin 24; Described plastic bead 23 adopts high-temperature resistance plastice to make, the material of described sequin 24 can be plastics, copper or steel, be provided with center line on it and be a plurality of round tube hole 24a along the mobile direction of fluid, in order to guarantee that described plastic bead 23 can not pass round tube hole 24a and leave screen pack 21, the radius of round tube hole 24a is less than the radius of plastic bead 23.

The filter of the utility model embodiment two owing to be provided with plastic bead 23, can reduce refrigerant fluid and produce disturbance in housing, reduce " giving a tongue-lashing " sound that sends, improve the tonequality of air-conditioner, refrigerant fluid fully mixes the formation sinuous flow in filter simultaneously, is more evenly distributed.
