Referring to fig. 1, fig. 2 and fig. 5, a condensation exhaust structure 100 is provided according to an embodiment of the present invention. The condensation exhaust structure 100 is used for the household appliance 200. The home appliance 200 includes a cavity 110. Condensation exhaust structure 100 includes aviation baffle 10 and condenser pipe 20, air inlet 12 has been seted up to aviation baffle 10, gas vent 14 and the wind channel 16 of intercommunication air inlet 12 and gas vent 14, condenser pipe 20 is located wind channel 16, the one end of condenser pipe 20 is used for leading-in steam in cavity 110, a plurality of flow equalizing holes 22 have been seted up to the pipe wall of condenser pipe 20, flow equalizing hole 22 communicates wind channel 16, condenser pipe 20 slope sets up so that the water of condensation flows back to cavity 110 in condenser pipe 20.

The condensation exhaust structure 100 of the above embodiment, the steam discharged from the cavity 110 enters the condensation pipe 20 for condensation, and is discharged into the air duct 16 through the flow equalizing hole 22, and then exchanges heat with the cold air in the air duct 16, and then is discharged from the exhaust port 14, because the condensation pipe 20 is obliquely arranged, the condensed water in the condensation pipe 20 can flow back to the cavity 110 of the household appliance 200, so that the content of the steam discharged to the exhaust port 14 is reduced, and the problems of mildew and the like caused by the external environment of the household appliance 200 are avoided.

Referring to fig. 4, in some embodiments, the air guiding plate 10 is tapered along the direction from the air inlet 12 to the air outlet 14. Therefore, the steam is favorably discharged from the air deflector 10, and the structure is simple.

Specifically, in one embodiment, the air deflector 10 may be an equilateral trapezoid, with the air inlet 12 disposed at an upper base of the equilateral trapezoid and the air outlet 14 disposed at a lower base of the equilateral trapezoid.

In one embodiment, the condensation duct 20 may have a U-shape as a whole, and the inclined arrangement of the condensation duct 20 may be understood that one end of the condensation duct 20 for guiding the steam in the cavity 110 is lower than the other end of the condensation duct 20, so that the condensed water in the condensation duct 20 may flow back to the cavity 110. Referring to fig. 5 and 6, in some embodiments, the condensation tube 20 includes a heat exchange tube 24 and a flow equalizing tube 26, a first end a of the heat exchange tube 24 is used for guiding the steam into the cavity 110, a second end B of the heat exchange tube 24 is connected to one end C of the flow equalizing tube 26, and a plurality of flow equalizing holes 22 are formed in a wall of the flow equalizing tube 26 and are arranged along a length direction L of the flow equalizing tube 26.

In this way, the heat exchange pipe 24 can cool part of the steam entering the heat exchange pipe 24, and the rest of the steam can be discharged from the flow equalizing hole 22 and uniformly mixed with the cold air in the air duct 16 and then discharged from the air outlet 14, so that the content of the steam discharged from the air outlet 14 is reduced and the steam is uniformly distributed.

Specifically, the material of the heat exchange tubes 24 and the flow straightener 26 may be plastic, stainless steel, or aluminum. The hot vapor discharged from the cavity 110 enters the cold heat exchange tube 24 and is condensed on the inner wall surface of the heat exchange tube 24, so as to generate condensed water, the uncondensed vapor enters the flow equalizing tube 26 and is further cooled to generate condensed water, and the condensed water in the heat exchange tube 24 and the condensed water in the flow equalizing tube 26 both flow back to the cavity 110. Eventually, the remaining vapor will exit the flow equalization holes 22 into the air chute 16.

Referring to fig. 6, in some embodiments, the second end B of the heat exchange tube 24 is higher than the first end a of the heat exchange tube 24, and one end C of the flow equalizing tube 26 connected to the second end B of the heat exchange tube 24 is higher than the second end B of the heat exchange tube 24. In this way, the condensed water in the heat exchange pipe 24 and the condensed water in the equalizing pipe 26 are easily returned to the cavity 110.

Specifically, the condensed water in the equalizing pipe 26 flows from one end C of the equalizing pipe 26 to the second end B of the heat exchanging pipe 24, then flows from the second end B of the heat exchanging pipe 24 to the first end a of the heat exchanging pipe 24, and finally flows back to the cavity 110. And the condensed water in the heat exchange tube 24 flows from the second end B of the heat exchange tube 24 to the first end a of the heat exchange tube 24, and finally flows back to the cavity 110.

Referring to fig. 3, 5 and 6, in some embodiments, the condensation tube 20 includes a connection tube 28, and the connection tube 28 connects the second end B of the heat exchange tube 24 and one end C of the flow equalizing tube 26. In this manner, the steam passing through the heat exchange pipe 24 can enter the homoflow pipe 26 through the connection pipe 28.

In particular, the connection tube 28 may be a hose, such as a silicone hose. The connection pipe 28 may be arc-shaped and disposed outside the air deflection plate 10, and penetrates the air deflection plate 10 to connect the heat exchange pipe 24 and the flow equalizing pipe 26.

Referring to fig. 1 and 5, in some embodiments, the heat exchange tube 24 includes a tube body 242 and a plurality of fins 244, and the plurality of fins 244 are spaced apart from each other on an outer surface of the tube body 242. In this manner, the outer surface area of the heat exchange tube 24 can be increased by the fins 244, so that the heat exchange efficiency of the heat exchange tube 24 can be improved.

Specifically, the material of the fins 244 may be stainless steel, and the shape of the fins 244 may be rectangular, square, or circular. The fins 244 can provide a significant amount of cooling to the vapor flowing through the heat exchange tubes 24, thereby allowing more vapor to cool within the heat exchange tubes 24.

Referring to fig. 5, in some embodiments, the flow equalizing tube 26 is cylindrical, and the plurality of flow equalizing holes 22 are uniformly spaced along the length L of the flow equalizing tube 26. In this way, the steam discharged from the flow equalizing holes 22 is uniformly distributed, so that a good flow equalizing effect of the steam can be achieved.

Specifically, the flow equalizing holes 22 are one or more of polygonal, circular and elliptical in shape. As such, this allows the condensation exhaust structure 100 to be adapted to various home appliances 200. In the example of fig. 5, the plurality of equalizing holes 22 are all circular in shape.

In one embodiment, the flow equalization holes 22 are circular. A plurality of flow equalizing holes 22 set up the last wall at flow equalizing pipe 26, steam through flow equalizing pipe 26 discharges from a plurality of flow equalizing holes 22 and gets into wind channel 16, the static pressure that produces when utilizing steam to flow through flow equalizing pipe 26's last wall makes steam to carry out the effect of reposition of redundant personnel better like this, thereby make the steam distribution that arrives gas vent 14 more even, and partial steam also can take place the condensation in the lower flow equalizing pipe 26 of temperature, thereby reducible content of discharging to the steam of gas vent 14.

Referring to fig. 1, 2 and 5, in some embodiments, the condensation duct 20 is connected to an exhaust duct 30, and the exhaust duct 30 is used for guiding the steam in the cavity 110 to the condensation duct 20. Thus, the steam in the home appliance 200 can be rapidly introduced into the heat exchange pipe 24 through the exhaust pipe 30.

Specifically, one end of the exhaust pipe 30 is connected to the steam inlet 246 of the heat exchange pipe 24, and the other end of the exhaust pipe 30 is connected to the steam outlet inside the cavity 110. The steam exhausted from the chamber 110 enters the chamber 110 through the exhaust pipe 30 and the steam inlet 246. The exhaust pipe 30 may be a flexible pipe resistant to high temperature. The exhaust tube 30 may be bent at an angle, such as 90 degrees.

Referring to fig. 2, in some embodiments, the condensation and exhaust structure 100 includes a fan 40, the fan 40 is connected to the air inlet 12, and the condensation pipe 20 is disposed near the air inlet 12 relative to the air outlet 14. In this way, the blower 40 can blow a large amount of air with a low temperature through the air inlet 12, so as to mix with the steam discharged from the condensation pipe 20, thereby achieving the purposes of cooling and dehumidifying.

Specifically, the air outlet of the fan 40 is communicated with the air inlet 12 of the air deflector 10, when the fan 40 is started, a large amount of air with a low temperature can be drawn from the outside and discharged into the air deflector 10, the steam with a high temperature discharged from the condensation pipe 20 is mixed with the air with a low temperature to generate condensed water, and the condensed water flows back to the exhaust pipe 30 along the condensation pipe 20.

Specifically, in summary, the operation principle of the condensation exhaust structure 100 is as follows: the steam enters the heat exchange tube 24 through the exhaust pipe 30, and the steam can exchange heat with the tube body 242 and the fin 244 of the heat exchange tube 24, so that the temperature of the steam flowing in the heat exchange tube 24 can be lowered, and the steam can be condensed. The flowing steam transfers a portion of the energy to the heat exchange tubes 24, and the heat exchange tubes 24 increase in temperature. The cool air flowing outside the heat exchange pipe 24 takes away the heat of the heat exchange pipe 24. The cold air outside the heat exchange tube 24 continuously exchanges heat with the steam inside the tube body 242 through the heat exchange tube 24, the steam is continuously condensed on the inner wall surface of the tube body 242, and a large amount of condensed water is generated inside the heat exchange tube 24. The second end B of the heat exchange tube 24 is slightly higher than the first end a of the heat exchange tube, so that the condensed water can flow back to the exhaust pipe 30 along the inner wall surface of the heat exchange tube 24 and then flow back to the cavity 110.

Further, a large amount of vapor is condensed at the heat exchange pipe 24, and a part of the uncondensed vapor flows into the equalizing pipe 26 along the connection pipe 28. The upper wall surface of the flow equalizing pipe 26 is provided with a row of flow equalizing holes 22 which are arranged at intervals. The effect of uniform discharge of steam along the flow equalizing holes 22 is achieved by the static pressure created by the air as it flows through the top of the interior cavity of the flow equalizing tube 26. Since the outside air of the flow straightener 26 continuously cools the flow straightener 26, the steam condenses within the flow straightener 26 to produce condensed water. The second end D of the flow equalizing pipe 26 is higher than the first end C of the flow equalizing pipe 26, so that the condensed water can be returned to the connection pipe 28 along the inner wall surface of the flow equalizing pipe 26. And the second end C of the connection pipe 28 is higher than the first end B of the connection pipe 28, so that the condensed water can be refluxed to the heat exchange pipe 24 along the inner wall surface of the connection pipe 28. The second end B of the heat exchange tube 24 is slightly higher than the first end a of the heat exchange tube 24, so that the condensed water can flow back to the exhaust pipe 30 along the inner wall surface of the heat exchange tube 24 and then flow back to the cavity 110. The first end C of the flow-equalizing tube 26 is an open end and the second end D of the flow-equalizing tube 26 can be a potted end.

It should be noted that, in the embodiment of the present invention, the path of the condensed water returning is the same as the path of the steam entering the condensation duct 20, but the direction is opposite. The condensed water flows back from the condenser pipe 20 to the exhaust pipe 30 and finally enters the chamber 110. The path and direction of the steam entering the condensation duct 20 are from the cavity 110 to the exhaust duct 30, and finally to the condensation duct 20.
