The refrigerant of the invention can be cooling water or cooling air.

In some embodiments of the present invention, as shown in fig. 2 and 4, a refrigerant conduit 33 for inputting a refrigerant to the condensation channel is disposed on an outer wall of the condensation channel, a cross-sectional line 34 between an inner wall surface of the condensation channel and the refrigerant conduit 33 is an ellipse, and a region defined by the cross-sectional line 34 forms a refrigerant inlet 35 of the condensation channel.

In the invention, the refrigerant guide pipe 33 is arranged on the outer wall of the condensation channel, and the refrigerant guide pipe 33 is arranged obliquely, so that the refrigerant guide pipe 33 and the inner wall surface of the condensation channel form the intersecting line 34 with an oval structure, as shown in fig. 4, when the refrigerant enters the condensation channel, the refrigerant does not enter in a single flow direction, but forms a dispersed flow direction on an oval surface, therefore, the refrigerant completes the first flow distribution when entering, the heat and mass exchange rate of the refrigerant and the hot and humid air is improved, the condensation efficiency of the refrigerant on the hot and humid air is further improved, and the drying efficiency of the clothes treatment equipment is further improved.

The condensation channel includes a condenser body 31 and a condenser cover 32. The refrigerant guide pipe 33 is disposed on an outer wall of the condenser cover 32, a cross-sectional line 34 between an inner wall surface of the condenser cover 32 and the refrigerant guide pipe 33 is an ellipse, an area defined by the cross-sectional line 34 forms a refrigerant inlet 35 of the condensation channel, and an axis of the refrigerant guide pipe 33 extends in a transverse direction.

The refrigerant of the invention is preferably tap water, the solubility of air in the tap water is low, and the tap water is used as the refrigerant, so that the refrigerant has the advantages of reliable source and simple recovery. In addition, the water inlet assembly of the wall-mounted clothes treating apparatus is generally disposed below the clothes treating tub 10, and the air outlet 11 of the clothes treating tub 10 is also generally disposed at a lower position, and the refrigerant inlet 35 is disposed at a higher position. Thus, under the action of the lifting force, the damp and hot air moves from the lower part to the upper part, and under the action of the gravity, the refrigerant moves from the upper part to the lower part, in the process of cross convection, the refrigerant condenses the water vapor in the damp and hot air into condensed water, and the condensed air is discharged from the air outlet 11 of the condensing channel.

The refrigerant guide pipe 33 is arranged on the outer wall of the condenser cover body 32, and the axis of the refrigerant guide pipe 33 is arranged along the transverse extension, so that the refrigerant guide pipe 33 is convenient to be communicated with a water inlet component of the clothes treatment equipment, and the refrigerant can be fully dispersed in the transverse direction after entering a condensation channel through the refrigerant guide pipe 33, and the area of the refrigerant moving from the upper part to the lower part is increased.

In a preferred embodiment of the present invention, the ratio of the major axis to the minor axis of the intersecting line 34 is in the range of 4:1 to 6: 1. .

Specifically, the shape of the intersecting line 34 is an ellipse, and the ratio of the major axis to the minor axis of the ellipse is set to be in the range of 4:1 to 6:1, so that the ellipse as a whole is elongated, and further, the refrigerant is sufficiently dispersed in the transverse direction, and the area of the refrigerant moving from the top to the bottom is increased.

In addition, the ratio of the size of the long axis of the ellipse to the transverse size of the condenser cover 32 is 2: 5-3: 5.

In some embodiments of the present invention, in order to further guide the flow direction of the refrigerant in the condensation channel, the inner wall surface of the condenser cover 32 is provided with a guide plate 36 protruding from the inner wall surface, and the guide plate 36 has an intersection with an extension line of a long axis of the intersecting line 34.

In detail, as shown in fig. 4, after the refrigerant enters the condensation channel through the refrigerant inlet 35 having the oval structure, although the refrigerant is distributed for the first time by the oval structure, if the entering speed of the refrigerant is high, a large amount of the refrigerant moves along the long axis direction of the oval structure, which is not favorable for the dispersion of the refrigerant. Therefore, the guide plate 36 is arranged in the downstream direction of the refrigerant inlet 35, when the refrigerant flows along the long axis direction of the oval structure, the refrigerant impacts the guide plate 36, and the flow direction of the refrigerant is changed under the blocking action of the guide plate 36, so that secondary refrigerant distribution is realized.

The guiding plate 36 may be a flat plate structure, and the guiding plate 36 of the flat plate structure has a reflection effect on the refrigerant, so as to change the flow direction of the refrigerant.

However, in a preferred embodiment of the present invention, the guide plate 36 has an arc-shaped configuration, a convex surface of the guide plate 36 faces the refrigerant inlet 35, and the guide plate 36 having the convex surface configuration has a radiation effect on the refrigerant, thereby further increasing a contact area between the refrigerant and the hot and humid air.

In detail, in order to further enhance the condensing effect of the refrigerant on the hot and humid air, the refrigerant redistributor 37 capable of distributing the refrigerant for the third time is disposed on the inner sidewall of the condenser cover 32. The refrigerant is diffused by the guide plate 36 to flow in all directions of the condensation passage, but a part of the refrigerant flows along the inner sidewall of the condenser cover 32 by the guide plate 36. Therefore, in order to sufficiently cover the inner wall of the condenser cover 32 with the part of the refrigerant, a refrigerant redistributor 37 is provided in the downstream direction of the guide plate 36.

It should be noted that the tangent line of the end of the guiding plate 36 from which the refrigerant is separated should fall into the inlet of the refrigerant redistributor 37 to redistribute the refrigerant.

In some embodiments of the present invention, as shown in fig. 4, in order to prevent the condenser cover 32 from being deformed due to a large temperature gradient in the condensation passage, a reinforcing rib 321 is provided on an outer wall of the condenser cover 32.

In detail, the ribs 321 include a transverse rib 321, a longitudinal rib 321, and an arc rib 321, and the respective ribs 321 are arranged to cross on the outer wall surface of the condenser cover 32.
