During the drying process of the all-in-one washing and drying machine, cooling water can be supplied to the condensation passage through the cooling water pipe 2, and the humid and hot air discharged from the inner cylinder 4 and the outer cylinder 5 enters the condensation passage from the air inlet 19, and the condensation The cooling water in the channel performs heat exchange, and the moisture in the hot and humid air is condensed into water, and the condensed air becomes relatively dry cold air, which is then discharged through the air outlet 18, and the cooling water and condensed water are discharged from the lower air inlet 19 discharge.

Continuing to refer to FIG. 3 to FIG. 5 , the condensation channel includes two double helical channels arranged side by side and independent of each other.

Exemplarily, two double-helix passages are arranged side by side, and the two double-helix passages are independent of each other. There are two gas inlets 19, which communicate with the two double-helix passages respectively. After a double helix channel, it rotates and rises along the double helix channel without mutual interference, and is finally discharged from the gas outlet 18. Wherein, only one air outlet 18 is provided on the body 1 of the condenser, and the tops of the two double helical passages communicate with the air outlet 18 .

This adjustment and change of the specific structural form of the water retaining structure 10 does not deviate from The principle and scope of the present invention should be limited within the protection scope of the present invention.

Continuing to refer to Fig. 4 and Fig. 5, on the front side wall of the double helical channel, a first arc-shaped structure 11, a second arc-shaped structure 12 and a structure between the first arc-shaped structure 11 and the second arc-shaped structure 12 are arranged. Distributing structure 13, the distributing structure 13 is located below the water retaining structure 10, the left side wall 14 and the right side wall 15 of the double helix channel are all arranged in an arc shape, and the two ends of the left side wall 14 are respectively connected with the first arc structure 11 and the first arc structure 11. The left end of the rear side wall 16 is smoothly connected, and the two ends of the right side wall 15 are respectively smoothly connected with the second arc structure 12 and the right end of the rear side wall 16 .

Continuing to refer to Fig. 4 and Fig. 5, the air inlet 19 is arranged on the rear side wall 16 of the double helical passage, and the split flow structure 13 is opposite to the air inlet 19, and through such arrangement, the gas entering from the air inlet 19 can just Hitting on the distribution structure 13, the distribution structure 13 can divide the airflow into two airflows, which are denoted as the first airflow and the second airflow, and can make the first airflow enter the second airflow roughly along the tangential direction of the first arc-shaped structure 11. An arc structure 11, under the impetus of the follow-up air flow, the first air flow can rotate counterclockwise along the left part of the first arc structure 11, the left side wall 14 and the rear side wall 16, and can make the second air flow Enter the second arc-shaped structure 12 roughly along the tangential direction of the second arc-shaped structure 12, and under the impetus of the subsequent airflow, the second airflow can follow the second arc-shaped structure 12, the right side wall 15 and the rear side wall 16. The right part rotates clockwise up.

The inner wall of the second gas channel rotates and rises, and the second airflow can rotate and rise along the inner wall of the second gas channel.

The condenser of the present invention is creatively provided with a split flow structure 13 on the front side wall of the double helical channel, and the gas entering from the air inlet 19 is divided into a first air flow and a second air flow by the flow split structure 13, so that the first air flow and the second air flow The second airflows rotate up respectively, and by making the first airflow and the second airflow rotate up, the strokes of the first airflow and the second airflow in the condensing channel become longer, thereby improving the cooling effect.

In addition, the two swirling airflows carry scattered cooling water splashes, forming a "whirlwind" spray in the condensation channel. By controlling the amount of cooling water, a vortex-shaped spray of a certain liquid level is formed in the condensation channel, and the air flow passes through this At the same time, at the air inlet 19 where lint accumulation is most likely to form, the fluctuating water spray is used to flush the bottom of the condensation channel in real time to improve the filtering effect on lint. The amount of cooling water in the channel reaches a dynamic balance.

Preferably, as shown in FIG. 6 and FIG. 7 , the water blocking structure 10 is disposed near the top of the flow distribution structure 13 . By arranging the water retaining structure 10 close to the top of the diversion structure 13, the cooling water can meet the two helical airflows immediately after being dispersed, which can better filter lint and condense.

In addition, through such an arrangement, the water retaining structure 10 can also be kept away from the air outlet 18 , which can prevent water from splashing from the air outlet 18 to the fan, and can also prevent the water from being carried into the inner cylinder 4 by the air flow, resulting in low drying efficiency.

When the first airflow and the second airflow meet , the movement tendency of the first airflow and the movement tendency of the second airflow are both towards the front side wall, so when the first airflow and the second airflow meet, they can interact, so that the first airflow can smoothly move towards the first arc The arc-shaped structure 11 moves, and the second airflow can smoothly move toward the second arc-shaped structure 12 .

It should be noted that, in order to ensure that the first airflow and the second airflow can rotate and rise independently, a middle partition can be arranged in the double helical channel, and the front side of the middle partition is connected with the first arc structure 11 and the second arc structure 11 respectively.

After the cooling water enters the main water tank 171, it flows down along the main water tank 171, and then flows into the two branch channels respectively. The water groove 172 thus flows into the two double helical channels, and when the cooling water flows onto the water retaining structure 10, it is broken into splashes.

Preferably, as shown in Figures 6 and 7, the water retaining structure 10 is also arranged on the front side wall of the double helical channel, and the water retaining structure 10 is triangular, and the top of the water retaining structure 10 is aligned with the bottom of the branch water groove 172 At the end, the centerline of the water retaining structure 10 coincides with the centerline of the distribution structure 13, so that the cooling water is evenly dispersed.

Through such a setting, the two helical airflows can carry approximately the same amount of cooling water spray upwards, and the dehumidification and filtration are more uniform, which improves the filtering effect on lint and the condensation effect on airflow.
