Abstract

The utility model relates to a ventilating pipeline for a central air conditioner, comprising an outer pipe and an inner pipe. The wall of the inner pipe is provided with a netted through hole, the outer wall of the inner pipe is in a tenon type insertion and match with the inner wall of the outer pipe, in order to form a concavo-convex clamp structure, and various shapes of the cross sections of the inner pipe can be applied. One end of the inner pipe is sealed, while in use, and the other end is connected with a high pressure water pump. The cleaning water or the disinfecting liquid is pumped into the outer pipe, when the inner part of the outer pipe is needed to be cleaned, or the sterilization is needed to be processed to the inner part of the outer pipe, in order to guarantee the cleaness of the inner part of the ventilating pipeline. The outer pipe and the inner pipe adopt the tenon type match structure; the utility model is much more practical, especially during the prevalence of an infectious disease, with easy installation.

Description

The breather line of central air-conditioner

Technical field:

The utility model relates to central air-conditioner, particularly to the improvement of breather line.

Background technique:

The use of central air-conditioner is very common, as public places such as office building, market, hospital, school, Movie theaters.But the pipeline of the ventilation that is useful on is at present all made with iron sheet, adds thermal insulating material.In long-term using process, these pipe interiors are piled up dust gradually, become the hiding oneself of virus, bacterium, derived, the ground of breeding, and can't remove or clean, sterilization, degerming, make ventilation duct become the passage of the substance that spreads disease, serious harm people's health.

Summary of the invention:

The purpose of this utility model provides a kind of convenient central air-conditioner breather line that cleans dust, disinfection.

The utility model is made up of outer tube and interior pipe, and inner pipe wall has a plurality of through holes, and its outer wall patches to cooperate with outer tube wall tenon formula and constitutes concavo-convex snap-in structure.The tenon formula patches and cooperates concavo-convex snap-in structure to be made of tenon and tongue-and-groove, and tongue-and-groove is built in outer tube wall, and tenon is built in outer wall of inner tube, and is perhaps opposite.Tongue-and-groove can be made into swallow-tail form, or circular, or T shape, and tenon is made corresponding fit shapes.Interior pipe quantity is 1～4.The cross section of outer tube is circle or rectangle.The sectional shape of interior pipe can be circle, or oval, or rectangle, or triangle, or rhombus, or fan-shaped.Outer tube or interior pipe are made one by plastic injection-moulded drawing and its tenon type structure.

The utility model inwall has the plastics ventilation duct of spraying and cleaning apparatus, the dust that the flush away of can spraying water is at any time as required piled up, or spray the degerming sterilization that different disinfecting liquids carries out ventilation duct inside, to guarantee the cleaning of ventilation duct inside.Outer effective plastics of this ventilation or the plastics that are added with stabilizer are made, and have heat insulation function simultaneously, and effect of heat insulation is better, adopts tenon formula cooperating structure, and easy for installation, particularly during disease transmission, the utility model has bigger Practical significance.In addition, too under the dry situation, the of short duration spray globule can be heated to air at air.

Embodiment:

With reference to Fig. 1, outer tube 1 and interior pipe 2 are made by plastics, and its middle external tube 1 inwall is connected with 3 round tongue-and-grooves 4; In pipe 2 outer walls be connected with round tenon 5, each constitutes one with the pipe drawing moulding tenon and tongue-and-groove, inserts and gets final product so that interior pipe tenon aimed at when installing tongue-and-groove.In pipe 2 tube walls have densely covered radial direction through hole 3, for clear water or thimerosal spray and go out.Interior pipe can many, also can be one.Fig. 2 has represented that interior pipe is that tongue-and-groove, outer tube are the example of tenon, and the installation effect is identical.Fig. 3 represents that outer tube is a rectangle, and interior pipe is circular example.

Fig. 4～Fig. 8 represents the interior tube section of the part in numerous different cross section shapes respectively, and its common ground is that outer wall is connected with tenon or tongue-and-groove, and tube wall has the screen cloth through hole.The tenon shape can be made into various ways, swallow-tail form as shown in Figure 6, T shape shown in Figure 7.

During installation, each section outer tube and interior pipe are connect in succession by pipe, constitute constant slope in certain distance, lowest part connects water pipe, and each pipe converges to exhausted bath box.During use, interior Guan Yiduan sealing, the other end is connected with high-pressure water pump, maybe needs carry out disinfection when sterilizing to outer tube inside when needs clean outer tube inside, need pump into clear water or thimerosal gets final product.

If outer tube adopts the foaming type plastics, then heat-shielding performance is better, need not the outsourcing thermal insulating material.
