Technical Field

The utility model relates to the technical field of washing equipment, and particularly provides a condenser and clothes treatment equipment with the same.

Background

At present, most of condensing type washing and drying integrated machines are provided with a drying module on a drum washing machine, wherein the drying module comprises a drying fan, an electric heater, a condenser and other corresponding components. The condenser is usually formed with an airflow channel for allowing airflow to pass through, and the hot and humid air from the inner drum enters the airflow channel through an air inlet of the condenser and then is discharged through an air outlet. The condenser is provided with a water filling port, and an external water source enters the condenser through the water filling port to be used as condensed water. Thus, the hot and humid air introduced into the air flow passage is contacted with the condensed water, mixed, and cooled.

However, the water injection port and the water flow channel are usually located at one side of the condenser, and it is difficult to ensure uniform distribution of water flow in the actual operation process, so that the hot and humid air entering the condenser and the condensed water cannot be fully contacted and mixed, and the condensing efficiency is low. In addition, since the water flow coverage is limited, if the thread scraps and the like carried in the hot and humid air are accumulated in the area which can not be covered by the water flow, the flow resistance in the condenser is increased after the operation time is prolonged, and the drying effect is deteriorated. Moreover, the accumulation of debris such as lint can cause bacteria to grow in the condenser.

Accordingly, there is a need in the art for a new solution to the above problems.

The condenser is provided with a condensation chamber, the condensation chamber is provided with an air inlet and an air outlet, and hot and humid air from the inner cylinder enters the condensation chamber through the air inlet and is exhausted from the air outlet after being cooled. The upper portion of condensation chamber is provided with the water inlet, and outside water can enter into the condensation chamber through the water inlet in, and then carries out the condensation to the damp and hot air that flows through the condensation chamber, can also wash the inner wall of condensation chamber simultaneously, smugglies secretly in the damp and hot air and deposit the line bits on the inner wall of condensation chamber and wash totally. The inner wall of condensation chamber is provided with the water conservancy diversion unit in the position that is close to the water inlet, can guide through this water conservancy diversion unit to get into the rivers flow in the chamber via the water inlet to can make rivers disperse and open, rivers that disperse like this just can be more fully with the damp and hot air contact of the condensation chamber of flowing through, improve condensation efficiency.

In a preferred embodiment of the present invention, the flow guide unit includes a first flow guide member and a second flow guide member disposed on an inner wall of the condensation chamber, an angle is formed between an axial direction of the water inlet and a vertical direction, and when there is no blocking or guiding, condensed water entering the condensation chamber through the water inlet initially flows along the axial direction of the water inlet and then flows downward under the action of gravity.

Preferably, the height that the part that first water conservancy diversion component is close to the water inlet is greater than the height that its part is kept away from the water inlet, this is because outside rivers enter the condensation chamber through the water inlet at the beginning, because circulation channel increases suddenly, rivers can outwards spread, and first water conservancy diversion component is located the axis direction's of water inlet downside, the height that first water conservancy diversion component is close to the part of water inlet is great, just so can block rivers and directly flow downwards through the water conservancy diversion unit, then the part of keeping away from the water inlet by first water conservancy diversion component guides the comdenstion water to second water conservancy diversion component again to can be better with comdenstion water conservancy diversion to second water conservancy diversion component. And/or, the ratio of the height of the part of the first flow guide component far away from the water inlet to the thickness of the condensation chamber is 0.15-0.3, and the thickness of the condensation chamber is limited, so that the first flow guide component can be ensured to have enough height to guide the condensed water to the second flow guide component, and too much space in the condensation chamber can not be occupied due to too high first flow guide component, and then the circulation space of the damp and hot air in the condensation chamber is reduced, and a better condensation effect can be obtained.

Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention. Although the embodiment is described by taking a tumble dryer as an example, the utility model can also be applied to other types of clothes treatment equipment such as a tumble dryer, a pulsator type washer/dryer, a mother-and-daughter machine, and the like.

Generally, a condensing washing and drying all-in-one machine is formed by adding a drying module to a drum washing machine, the drying module generally comprises a condenser, a fan and a heater, under the action of the fan, humid and hot air enters the condenser after coming out of an inner drum and is condensed, then enters the heater and is heated, and then enters the inner drum, and the operation is repeated in the way until clothes in the inner drum are dried. The condenser is provided with a water injection port, and an external water source enters the condenser through the water injection port to cool the damp and hot air entering the condenser. However, the water injection port and the water flow channel are usually located at one side of the condenser, water flow is easily distributed unevenly in the condenser, moist hot air and condensed water entering the condenser cannot be fully contacted and mixed, and condensation efficiency is low. On the other hand, the condensed water is not uniformly distributed, and the lint deposited in the condensing chamber may not be sufficiently washed away, so that the resistance of the air flowing through the condensing chamber is increased, and the drying effect is poor. Therefore, the utility model provides a condenser which is provided with a condensation chamber, wherein a flow guide unit is arranged in the condensation chamber, and condensed water entering the condensation chamber is dispersed through the flow guide unit, so that a better condensation effect can be obtained, and thread scraps deposited in the condensation chamber can be washed clean, thereby being beneficial to drying clothes.

In particular, a possible arrangement of the condenser of the present invention is explained with reference to fig. 1 and 2. Fig. 1 is a structural view of a condenser according to an embodiment of the present invention, and fig. 2 is a partial sectional view of the condenser according to the embodiment of the present invention. It will be understood by those skilled in the art that, in order to better explain the structure of the present application, only a partial structure of the condenser is shown in a sectional view in fig. 2, and such a partial structure sectional view should not be taken as a specific limitation to the structure of the condenser of the present application.

As shown in fig. 1 and 2 and according to the orientation shown in fig. 2, the condenser has a condensation chamber, the lower portion of the condensation chamber is provided with an air inlet 11, and the upper portion of the condensation chamber is provided with an air outlet 12, so that an air flow passage allowing hot and humid air to pass through is formed in the condensation chamber, and hot and humid air coming out of the inner drum enters the condensation chamber from the air inlet 11 at the lower portion and is then discharged from the air outlet 12 at the upper portion. The air exhausted from the air outlet 12 is heated by the heater, and then enters the inner drum through the air return inlet to continuously dry the clothes. Obviously, the air inlet 11 may be formed in the upper portion of the condensation chamber, and the air outlet 12 may be formed in the lower portion of the condensation chamber, and those skilled in the art may flexibly select the forming positions of the air inlet 11 and the air outlet 12 on the condenser according to the specific application scenarios as long as an air flow channel allowing air to pass through is formed in the condensation chamber.

As shown in fig. 1 and 2, a water inlet 13 is provided at an upper portion of the condensation chamber, and external water enters the condensation chamber through the water inlet 13, then flows downward along an inner wall of the condensation chamber, and is in counter-flow contact with hot and humid air from bottom to top, thereby achieving a purpose of cooling the hot and humid air. Meanwhile, the inner wall of the condensation chamber can be washed, the filings carried in the damp and hot air and deposited on the inner wall of the condensation chamber are washed clean, and the washed filings are discharged from the air inlet 11. Of course, if the air outlet 12 is formed at the lower portion of the condensation chamber, the condensed water will be discharged from the air outlet 12 after washing the inner wall of the condensation chamber. Be provided with water conservancy diversion unit 3 on condensation chamber's the inner wall, this water conservancy diversion unit 3 sets up in the position that is close to water inlet 13, can guide the rivers that enter into condensation chamber via water inlet 13 and flow to can make the rivers dispersion open, the rivers that disperse like this just can be more abundant with the damp and hot air contact of flowing through condensation chamber, improve condensation efficiency. And the scattered condensed water can flush the thread scraps deposited on all positions of the inner wall of the condensation chamber, and air can pass through the condensation chamber without resistance, so that the drying of clothes is facilitated.

A possible arrangement of the flow guiding unit 3 of the condenser of the present invention is explained below with reference to fig. 1 to 5. Fig. 3 is an enlarged view of a portion a in fig. 2, fig. 4 is a partial sectional view of a condenser according to an embodiment of the present invention, and fig. 5 is an enlarged view of a portion B in fig. 4.

As shown in fig. 1 to 5 and in the orientation shown in fig. 2, the flow guide unit 3 comprises a first flow guide member 31 and a second flow guide member 32 which are arranged on the inner wall of the condensation chamber, the axial direction of the water inlet 13 is inclined downward from left to right, and the axial direction of the water inlet 13 is approximately inclined downward from left to right, and the condensed water entering the condensation chamber through the water inlet 13 initially flows in the direction from left to right and inclined downward, and then flows downward under the action of gravity. Wherein the first flow guiding member 31 extends along the axial direction of the water inlet 13 and is located at the lower side of the axial direction of the water inlet 13 (i.e. below the axial line of the water inlet 13 in fig. 2), so that the condensed water entering the condensation chamber through the water inlet 13 can flow along the axial direction of the water inlet 13 under the guiding action of the first flow guiding member 31. Of course, the first flow guide member 31 does not extend strictly in a straight direction in the axial direction of the water inlet 13, as long as it extends substantially in the axial direction of the water inlet 13. The second flow guide member 32 is disposed near a downstream end of the first flow guide member 31 in the flow direction of the condensed water. The condensed water entering the condensing chamber through the water inlet 13 is guided to the second guide member 32 by the first guide member 31, and the second guide member 32 receives and disperses the condensed water guided by the first guide member 31, so that the condensed water is dispersed in the condensing chamber, and the dispersed condensed water can be more fully contacted with the humid and hot air flowing through the condensing chamber.

Obviously, it is also possible that the second flow guiding member 32 is disposed close to the water inlet 13 and opposite to the water inlet 13, and the condensed water entering the condensation chamber through the water inlet 13 is dispersed by the second flow guiding member 32, and the dispersed condensed water flows downward by the flow guiding action of the first flow guiding member 31. The skilled person can flexibly select the specific arrangement of the first flow guiding member 31 and the second flow guiding member 32 in the condensation chamber according to the specific application scenario, so as to adapt to more specific application.

With continued reference to fig. 1 to 5, the first flow guiding member 31 is configured as an elongated rib, and the upstream end of the elongated rib extends to the water inlet 13 along the flow direction of the condensed water, so that the external water just enters the condensation chamber through the water inlet 13 and flows toward the second flow guiding member 32 under the guiding action of the elongated rib, thereby better guiding the condensed water to the second flow guiding member 32. Furthermore, the elongated rib substantially comprises a first part and a second part connected, the first part being the part close to the water inlet 13 and having a length substantially one quarter of the length of the elongated rib. The second part is the part far away from the water inlet 13, the length of the second part is approximately three quarters of the length of the strip rib plate, and the first part and the second part are in smooth transition. It can be seen that the height of the first portion is greater than the height of the second portion, because when the condensed water enters the condensation chamber from the water inlet 13, the circulation space is suddenly increased, and the condensed water enters the condensation chamber in a burst-like manner, so that the height of the first flow guiding member (i.e. the first portion) at a position close to the water inlet 13 should be relatively large, so that the condensed water can be guided well. If the height of this (first part) is not enough, some condensed water may flow downward directly from the water inlet without being guided and dispersed by the diversion unit 3, thereby affecting the condensation effect. The height of the first part is higher than that of the second part, so that the condensed water entering the condensation chamber through the water inlet 13 is firstly blocked and guided by the first part and then guided to the second flow guide member 32 by the second part.

Obviously, the height of the first flow guide member 31 may be uniform throughout. Of course, the first flow guiding member 31 may be provided in other shapes, such as an arc rib plate. The height and shape of the first flow guiding member 31 can be flexibly selected by those skilled in the art according to the specific application, as long as the condensed water entering the condensation chamber through the water inlet 13 can be guided to the second flow guiding member 32 by the first flow guiding member 31.

In one possible embodiment, the ratio of the height of the second portion of the first flow guiding member 31 (i.e. the dimension perpendicular to the plane of the paper in fig. 3) to the thickness of the condensation chamber is 0.15-0.3. This is because the second portion is mainly used to guide the condensed water to the second flow guiding member 32, and the thickness of the condensation chamber, which refers to the distance between the inner wall of the condensation chamber where the air inlet is provided and the inner wall located at the opposite side of the air inlet, is generally limited. If the height of the second portion of the first flow guiding member 31 is too short, there may be a portion of the condensed water flowing downward directly over the second portion and not guided to the second flow guiding member 32, and if the height of the second portion of the first flow guiding member 31 is too high, too much space of the condensing chamber may be occupied, resulting in a reduction in the circulation space of the hot and humid air, which is not favorable for the condensation of the hot and humid air. According to the utility model, the height of the second part of the first flow guide member 31 is limited to 0.15-0.3 of the thickness of the condensation chamber, so that the first flow guide member 31 can be ensured to have enough height to guide condensed water to the second flow guide member 32, and too much space in the condensation chamber is not occupied due to too high first flow guide member 31, and the circulation space of damp and hot air in the condensation chamber is reduced, thereby obtaining a better condensation effect. Preferably, the ratio of the height of the first flow guide member 31 to the thickness of the condensation chamber is 0.17.

In a possible embodiment, an angle between a tangent (i.e. an outlet tangent) of a downstream end of the first flow guide member 31 in a flow direction of the condensed water and a vertical direction is 15 to 20 degrees, that is, an outlet of the first flow guide member 31 extends downward, and the second flow guide member 32 is located at the downstream end of the first flow guide member 31, so that the condensed water entering the condensation chamber through the water inlet 13 first flows along an axial direction of the water inlet 13 substantially under the guidance of the first flow guide member 31, and then flows downward to the second flow guide member 32 at an outlet thereof along the outlet tangent direction, thereby better guiding the condensed water to the second flow guide member 32. Preferably, the exit tangent of the first flow guide member 31 is at an angle of 15 degrees to the vertical.

With continued reference to fig. 1 to 5, the second flow guiding member 32 is configured as an arc-shaped rib plate, the concave surface of the arc-shaped rib plate faces the first flow guiding member 31, so that the condensed water guided by the first flow guiding member 31 directly flows to the concave surface of the arc-shaped rib plate, and the condensed water entering the condensation chamber through the water inlet and guided by the first flow guiding member 31 is a bundle of water flow, so that the bundle of water flow is buffered and expanded after reaching the concave surface, so that the water flow coverage area is wider, the water flow coverage area can at least cover the area below the second flow guiding member 32, and part of the water flow can also expand towards two sides of the second flow guiding member 32, thereby achieving the purpose of dispersing the condensed water. Obviously, the second flow guiding member 32 may also be configured in other forms, such as a semi-elliptical rib plate, a curved rib plate, etc., and a person skilled in the art may flexibly select a specific configuration form of the second flow guiding member 32 according to a specific application scenario, as long as the second flow guiding member 32 can expand and disperse the water flow reaching the second flow guiding member.

With continued reference to fig. 1 to 5, the circular arc rib plate is provided with two openings 321, the two openings 321 are respectively arranged on the left half circular arc and the right half circular arc of the circular arc rib plate, and the condensed water reaching the second flow guide member 32 can respectively flow to different directions through the two openings 321 on the circular arc rib plate, so that the condensed water can be better dispersed. The size of each opening 321 along the circumferential direction of the circular arc rib plate is 1-3 mm, so that a part of condensed water reaching the second flow guide member 32 can pass through the two openings 321 respectively, and the condensed water can be dispersed in multiple directions. Preferably, the size of the opening 321 in the circumferential direction of the circular arc rib (i.e. the gap width shown in fig. 3) is 2 mm.

The two openings 321 may have the same size, both are 2mm, or different sizes, one is 1.5mm, and the other is 2.2mm, on the premise of not deviating from the principle of the present invention, a person skilled in the art may flexibly select the specific size of the opening 321 according to a specific application scenario, the size of the opening 321 is not too large, if the size is too large, the condensed water reaching the circular arc rib plate may all flow out through the opening 321, and the size of the opening 321 is not too small, and if the size is too small, the amount of the condensed water that can pass through the opening 321 is small. That is, the effect of dispersing the condensed water is affected by the size of the opening 321 being too large or too small, and in this embodiment, the size of the opening 321 in the circumferential direction of the circular arc rib plate is limited to 1 to 3mm in order to better disperse the condensed water.

Obviously, a greater number of openings 321, such as three or four, may be provided on the circular arc rib plate, and the plurality of openings 321 may be symmetrically distributed or asymmetrically distributed on the circular arc rib plate. The skilled person in the art can flexibly select the number of the openings 321 arranged on the circular arc rib plate, the arrangement mode and the like according to a specific application scene so as to adapt to a more specific application occasion.

As shown in fig. 1 to 5, the guide unit 3 further includes a third guide member 33 provided on an inner wall of the condensation chamber, the third guide member 33 being located at one side of the first guide member 31 in an axial direction of the inlet (i.e., a right side of the first guide member 31 in fig. 2), by which wash water entering the condensation chamber through the water inlet 13 can be blocked and the wash water can be guided to the second guide member 32. It should be noted that, in order to prevent the lint carried by the hot and humid air from depositing in the condensation chamber, during or after the condensation process, washing water is generally fed into the condensation chamber to wash the inner wall of the condensation chamber, so as to remove the lint deposited on the inner wall of the condensation chamber. In the condensation phase, the flow of the condensed water is not usually too large, and the condensed water is guided to the second flow guiding member 32 via the first flow guiding member 31, and the condensed water reaching the third flow guiding member 33 is smaller. In the rinsing phase, a larger amount of rinsing water is usually used in order to better rinse the inner walls of the condensation chamber. The part of the flushing water entering the condensation chamber through the water inlet 13 is guided by the first guide member 31 to reach the second guide member 32, and the part of the flushing water continuously flushes to the third guide member 33, so that the flushing water is prevented from directly flushing to the lower right of the condensation chamber and contacting with the humid and hot air entering the condensation chamber through the air inlet without being dispersed by the second guide member 32 under the blocking action of the third guide member 33. The washing water reaching the third guide member 33 is guided to the second guide member 32 by the third guide member 33, and then is dispersed by the second guide member 32, so that the washing water entering the condensation chamber through the water inlet 13 can be better dispersed, and the inner wall of the condensation chamber can be more completely washed.

With continued reference to fig. 1 to 5, the third diversion member 33 is provided with an arc-shaped rib, the distance between the arc-shaped rib and the first diversion member 31 is gradually reduced along the flowing direction of the washing water, and the washing water guided by the first diversion member 31 and the third diversion member 33 is gradually gathered towards the middle, so that the washing water can be better guided to the concave surface of the second diversion member 32, and the condensed water can be better dispersed. Obviously, the third flow guide member 33 may also be configured in other forms, such as a semi-elliptical rib plate, a curved rib plate, and the like, and a person skilled in the art may flexibly select a specific configuration form of the third flow guide member 33 according to a specific application scenario so as to adapt to a more specific application situation.

In a possible embodiment, the ratio of the height of the third flow guiding member 33 (i.e. the dimension perpendicular to the paper surface in fig. 3) to the thickness of the condensation chamber is 0.5-0.8, which is not too high or too low for the same reason as the height of the first flow guiding member 31, so that it is ensured that the third flow guiding member 33 has a sufficient height to block and guide the washing water to the second flow guiding member 32, and the third flow guiding member 33 does not occupy too much space in the condensation chamber due to too high height, thereby reducing the circulation space of the hot and humid air in the condensation chamber. It can be seen that the height of the third flow guiding member 33 is higher than the height of the first flow guiding member 31, because the third flow guiding member 33 is located at a lower position than the first flow guiding member 31, and the speed of the washing water entering the condensation chamber through the water inlet 13 reaches the third flow guiding member 33 is higher than the speed of the washing water at the first flow guiding member 31, so that a relatively high height is required to be able to block the washing water and guide the washing water to the second flow guiding member 32. Preferably, the ratio of the height of the third flow guide member 33 to the thickness of the condensation chamber is 0.57.

In a possible embodiment, an angle between a tangent of a downstream end of the third flow guide member 33 in the flow direction of the washing water (i.e., an outlet tangent of the third flow guide member 33) and an axis of the water inlet 13 is 50 to 80 degrees, and an angle between a tangent of an upstream end of the third flow guide member 33 in the flow direction of the washing water (i.e., an inlet tangent of the third flow guide member 33) and the axis of the water inlet 13 is 20 to 40 degrees, so that the third flow guide member 33 is disposed in a structure inclined downward from right to left, and the first flow guide member 31 is disposed in a structure inclined downward from left to right, so that the washing water flows downward and toward each other by the guide action of the first flow guide member 31 and the third flow guide member 33, thereby better guiding the washing water to the second flow guide member 32. Preferably, an angle between an outlet tangent of the third flow guide member 33 and an axis of the water inlet 13 is 63 degrees, and an angle between an inlet tangent of the third flow guide member 33 and the axis of the water inlet 13 is 20 degrees.

In a possible embodiment, the curvature of the third flow guiding member 33 is 0.5 to 1, and the central angle of the sector corresponding to the curvature is approximately 28.7 to 57.3 degrees, that is, the length of the third flow guiding member 33 is approximately between one twelfth and one sixth of the circumference of the concentric circle, which is neither too short nor too long, and the third flow guiding member 33 with the length can guide the condensed water located at the right side of the first flow guiding member 31 to the second flow guiding member 32. Compared with the first flow guiding member 31, the third flow guiding member 33 is closer to the air outlet 12 and has a height higher than that of the first flow guiding member 31, and if the third flow guiding member 33 is too long, it will occupy too much space and affect the flow of the air flow in the condensing chamber. Preferably, the arc of the third flow guide member 33 is 0.78.

As shown in fig. 1, 2 and 4 and in the orientation shown in fig. 2, the condenser further comprises a fourth flow guiding member 34 of substantially strip-like configuration arranged at the inner wall of the condensation chamber, the fourth guide member 34 extends along the air flowing direction, divides the lower portion of the condensing chamber between the air inlet 11 and the guide unit 3 into a first air duct and a second air duct, thus, the damp and hot air entering the condensation chamber through the air inlet 11 at the lower part is divided into two parts which respectively enter the first air duct and the second air duct from bottom to top, and the condensed water entering the condensation chamber from the water inlet 13 is dispersed under the action of the guide unit 3, and the moist and hot air respectively enters the first air channel and the second air channel and is fully contacted with the condensed water flowing to the first air channel and the second air channel in a counter-current manner, so that a better condensation effect can be obtained. Obviously, the fourth flow guiding member 34 may be formed by an outer wall of the condensation chamber being recessed inwards, or may be a rib-like structure disposed on an inner wall of the condensation chamber.

By the above arrangement, the condensed water entering the condensing chamber through the water inlet 13 at the upper part of the condensing chamber is firstly guided by the first guide member 31, flows downwards along the first guide member 31 to the second guide member 32, and part of the condensed water near the right is guided to the second guide member 32 through the third guide member 33, and the second guide member 32 receives and disperses the guided condensed water. The damp and hot air entering the condensing chamber through the air inlet 11 at the lower part of the condensing chamber respectively flows upwards through the first air channel and the second air channel which are formed by dividing the fourth flow guide component 34, and fully contacts with the condensed water dispersed by the second flow guide component 32 in the upward flowing process, so that a better condensing effect can be obtained. And the dispersed condensed water can more fully flush the thread scraps deposited on all positions of the inner wall of the condensation chamber, and air can pass through the condensation chamber without resistance, thereby being beneficial to drying clothes.

With continued reference to fig. 1, 2, 4 and 5, the side of the fourth flow guide member 34 facing the inner wall of the condensation chamber opposite to the fourth flow guide member 34 is formed with an elongated groove 341. The inner wall of the condensation chamber is provided with a support plate (not shown) having a length substantially the same as that of the fourth guide member 34 and a width substantially the same as that of the groove 341, toward the fourth guide member 34. In the assembled state, the supporting plate is inserted in the groove 341, and when the supporting plate is inserted, the side surface of the inner wall of the supporting plate, which is far away from the condensation chamber, abuts against the bottom of the groove 341, and the fourth flow guide member 34 abuts against the inner wall of the condensation chamber, so that the part of the condensation chamber, which is located between the air inlet 11 and the flow guide unit 3, can be better separated into a first air channel and a second air channel. Furthermore, the stability of the condensation chamber can also be enhanced by the abutment of the support plate with the fourth flow guide member 34.

Obviously, without departing from the principle of the present invention, when inserted, only the fourth flow guiding member 34 may abut against the condensation chamber, or only the side surface of the inner wall of the supporting plate away from the condensation chamber abuts against the bottom of the groove 341, and those skilled in the art may appropriately adjust the height of the supporting plate and/or the height of the groove 341 as long as the portion between the air inlet 11 and the flow guiding unit 3 can be divided into the first air duct and the second air duct.

Obviously, the side surface of the fourth flow guide member 34 may not be provided with the groove 341, and the side surface of the fourth flow guide member 34 may be provided with a plane which abuts against the support plate. Obviously, it is also possible to dispense with a support plate, the fourth flow guide member 34 directly abutting against the inner wall of the condensation chamber. The person skilled in the art can flexibly select the abutting mode of the fourth flow guiding member 34 with the inner wall of the condensation chamber according to the specific application scenario, so as to adapt to the specific application.

As shown in fig. 2, the first flow guiding member 31, the second flow guiding member 32, the third flow guiding member 33, and the fourth flow guiding member 34 are disposed on opposite sides of the condensation chamber corresponding to the inner wall of the air inlet 11, so that the hot and humid air entering the condensation chamber through the air inlet 11 first directly hits the inner wall of the opposite side of the side where the air inlet 11 is located, and is further divided into two parts by the fourth flow guiding member 34 disposed on the opposite side, and further fully contacts with the condensed water dispersed by the first flow guiding member 31, the second flow guiding member 32, and the third flow guiding member 33, thereby obtaining a better condensation effect.

In summary, in the preferred technical solution of the present invention, the flow guide unit 3 is disposed at a position close to the water inlet 13 on the inner wall of the condensation chamber, so as to guide the flow of the condensed water entering the condensation chamber through the water inlet 13 and disperse the condensed water, so that the condensed water can be more fully contacted with the hot and humid air flowing through the condensation chamber, thereby improving the condensation efficiency, better washing the inner wall of the condensation chamber, reducing the resistance in the condensation chamber, and facilitating the drying of the clothes. The condensed water entering the condensation chamber through the water inlet 13 is guided to the second flow guide member 32 by the first flow guide member 31 which is provided with the long strip-shaped rib plate, the condensed water entering the condensation chamber through the water inlet 13 is guided to the second flow guide member 32 by the third flow guide member 33 which is provided with the arc-shaped rib plate, the condensed water guided by the first flow guide member 31 and the third flow guide member 33 is received by the second flow guide member 32, and the condensed water reaching the second flow guide member 32 is dispersed through the condensed water and the openings 321 arranged on the condensed water, so that a better condensation effect is obtained. The part of the condensation chamber between the air inlet 11 and the guide unit 3 is divided into the first air channel and the second air channel by the fourth guide member 34, so that the hot and humid air entering the condensation chamber can be more fully contacted with the condensed water, and a better condensation effect can be obtained.
