Abstract

The utility model relates to an anti-pollution drainage device of air conditioner, in particular to a drainage device of air conditioner for discharging the condensed water, which comprises a bent tube and a tube joint. One interface of the bent tube runs to the cavity of the tube joint form bottom of the tube joint; the interface of the bent tube is provided with an interception device, and the position of the other end of the bent tube is higher than that of the interface extending into the cavity of the tube joint; the lateral wall of the tube joint is provided with an outlet. The utility model has simple and reasonable design of the structure. The interception device can be opened by utilizing the pressure formed by the condensed water itself in the bent tube, and then the condensed water is discharged; then the bent tube is closed automatically by the interception device through the subpressure and the internal gravity of the condensed water so as to prevent the niff and the bacteria in the sewer form entering the air conditioner system, thus avoiding the pollution of the circulating air of the air conditioner system and the unsafe hidden danger.

Description

The antifouling drainage arrangement of hermetic type

Technical field

The utility model relates to the antifouling drainage arrangement of a kind of air-conditioning, specifically relates to a kind of drainage arrangement of central air-conditioning row condensed water.

Background technology

The condensed water of existing central air conditioning equipment generally carries out draining by make water seal on pipeline, when summer air-conditioning freezes, because the effect of water seal, foul smell, pernicious gas, some reptiles even mouse etc. can not enter in the air-conditioning equipment by drainpipe, can the circulating air of air-conditioning not polluted.But during Winter heat supply, the water seal on the former condensing water conduit loses the water seal effect because of lack of water, when equipment moved, because suction function, foul smell, pernicious gas were inhaled into the circulating air that causes air-conditioning and pollute, simultaneously reptile even mouse etc. also can access arrangement in, form hidden danger.

Summary of the invention

The purpose of this utility model is to provide a kind of can be self-closing, good seal performance and the antifouling drainage arrangement of hermetic type simple in structure,

The purpose of this utility model is achieved in that

The antifouling drainage arrangement of a kind of hermetic type comprises bend pipe, also comprises pipe joint, one port of described bend pipe inserts into the inner the chamber from the pipe joint bottom, this bend pipe port is provided with cut-off equipment, and the position, another port of bend pipe is higher than the port that stretches into the pipe joint inner chamber, and the pipe joint sidewall is provided with discharge outlet.

Above-mentioned purpose also can be done further perfect by the following technical programs:

Described cut-off equipment is a ball float, and ball float is pressed on the bend pipe port freely.

Described cut-off equipment is a diaphragm seal, and diaphragm seal is pressed on the bend pipe port freely, and diaphragm seal one end links on the bend pipe sidewall.

Described bend pipe comprises interface tube, horizontal nozzle, grafting elbow, vertical segment, adapter elbow and straight length, and wherein straight length stretches into the pipe joint inner chamber, the junction liquid sealing between straight length and the pipe joint.

Described pipe joint comprises end cap and body, is threaded between end cap and the body, and discharge outlet is located on the body, and the straight length port that is provided with cut-off equipment is higher than discharge outlet.

Air-conditioning equipment is at the refrigerating operaton in summer, condensed water is transported to the pipe joint inner chamber by bend pipe, and in its chamber, form water seal, though at air-conditioning equipment operation condensed water drainage position is negative pressure, because the effect of water seal, foul smell, pernicious gas, some reptiles can not enter, and have avoided the pollution to circulating air.When the pressure of interface tube during greater than the straight length port pressure, cut-off equipment is opened under pressure differential and buoyancy function automatically, and the water that flows out straight length is discharged through discharge outlet.The aperture size of the cut-off equipment in the pipe joint is proportional with condensation water quantity, and reaches certain poised state with it.Air-conditioning equipment is in excessively season or Winter heat supply operation, evaporated condensation water produces, water seal can't form, and cut-off equipment relies on the gravity effect to finish sealed elbow, and the extraneous reliability of also having guaranteed the cut-off equipment sealing at atmospheric pressure greater than the pressure of bend pipe inner chamber.

The utility model structural design advantages of simple, the pressure that utilizes condensed water self to form in bend pipe is opened cut-off equipment, evaporated condensation water ejects, make cut-off equipment automatic airtight bend pipe by negative pressure and the gravity effect of self, the foul smell of prevention sewer and bacterium etc. enter air-conditioning system, avoid causing the circulating air of air-conditioning system to pollute and the formation hidden danger.

Description of drawings

Accompanying drawing 1 is embodiment 1 structural representation;

Accompanying drawing 2 is embodiment 2 structural representations.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

Embodiment 1, in conjunction with the accompanying drawings 1, the antifouling drainage arrangement of a kind of hermetic type, comprise by interface tube 1, horizontal nozzle 2, grafting elbow 3, vertical segment 4, bend pipe and pipe joint 8 that two nipple joint elbows 5 and straight length 6 are formed, pipe joint 8 comprises end cap 11 and body 12 again, be threaded between end cap 11 and the body 12, straight length 6 stretches into about 2/3 place in body 12 chambeies, and opening is free end and is in center in the pipe joint chamber, junction liquid sealing between straight length 6 and the body 12, straight length 6 free ports are provided with a ball float 7, ball float 7 freely is pressed on straight length 6 ports, and the diameter of ball float 7 should be greater than the internal diameter of

straight length

6, and 1 mouthful of position height of interface tube is greater than straight length 6 ports.In the bottom of body 12 discharge outlet 9 is arranged, straight length 6 free ports are higher than discharge outlet 9.When condensed water flows into from interface tube 1, because interface tube 1 height is greater than the formation pressure reduction of straight length 6 ports in bend pipe, ball float 7 is under pressure and self buoyancy function, and ball float 7 leaves straight length 6 ports, condensed water flows in body 12 chambeies, and then discharges through discharge outlet 9.When not arranging condensed water, ball float 7 dynamic pressures guarantee the airtight of port on straight length 6 ports.

Embodiment 2, and in conjunction with the accompanying drawings 2, the difference of embodiment 2 and embodiment 1 is to be stamped diaphragm seal 7 on the port of straight length 6, and mounting 7 one ends are hinged on the tube wall of straight length 6, guarantee that simultaneously the rotation of diaphragm seal 7 is no more than 60.
