As shown in fig. 1 to 5, the present embodiment proposes a washing and drying machine including a tub 100 and a drying module 200. Wherein, after the laundry completes the washing operation in the tub 100, the drying module 200 may be activated to perform the drying process on the laundry in the tub 100. For the specific operation modes of the washing tub 100 for washing the laundry and the drying module 200 for drying the laundry, reference may be made to the structural forms of the related components of the conventional washing and drying machine, which are not limited or described herein.

The conventional drying module 200 is composed of an electric heater 201 and a fan 202, the drying module 200 has an air blowing port and an air suction port, the air blowing port is communicated with the tub 100, the air inlet 11 of the lint removing module is communicated with the tub 100, and the air outlet 12 of the lint removing module is communicated with the air suction port of the drying module 200. In order to condense the high temperature and high humidity gas in the tub 100 and filter lint mixed in the gas during the drying process, the washing and drying machine is further provided with a lint removing module 300.

The lint removing module 300 comprises a condensation air duct 1 and a water inlet pipe 10. Wherein, the condensation air duct 1 is used for conveying air flow in the clothes drying process, and the water inlet pipe 10 is used for injecting water into the condensation air duct 1.

Wherein, condensation wind channel 1 is provided with air intake 11 and air outlet 12, and the bottom in condensation wind channel 1 forms water storage area 103, and the inside relative position with air intake 11 in condensation wind channel 1 forms windward side A. An air inlet 11 is arranged at the lower part of the condensation air duct 1, and an air outlet 12 is arranged at the upper part of the condensation air duct 1. The air flow output from the washing and drying machine enters the condensation air duct 1 through the air inlet 11 and is output from the air outlet 12.

In addition, the water inlet pipe 10 is arranged on the condensation air duct 1, and water output by the water inlet pipe 10 is used for cleaning the windward side A. In actual use, when the drying module 200 is activated to dry the laundry in the tub 100, the airflow containing the thread scraps generated during the drying process of the laundry in the tub 100 enters the condensing duct 1. The airflow enters the condensation air duct 1 through the air inlet 11 and impacts the windward side a, and the airflow is finally output from the air outlet 12 after being condensed and subjected to lint removing treatment through the water in the water storage area 103.

And for the windward side A, in the clothes drying process, due to the fact that the humidity of the air flow is high and the air flow is mixed with the thread scraps, the air flow impacts the windward side A, and a large amount of thread scraps are adhered to the windward side A. Along with the increase of the clothes drying time, the accumulated amount of the thread scraps on the windward side A is gradually increased, and the blockage of the condensation air duct 1 is further caused. And water is injected into the condensation air duct 1 through the water inlet pipe 10, so that the thread scraps on the windward side A are cleaned by the water output by the water inlet pipe 10.

In some embodiments, in order to enable the water output by the water inlet pipe 10 to comprehensively clean the thread scraps on the windward side a, a water diversion plate 13 is arranged inside the condensation air duct 1, the water diversion plate 13 is located above the windward side a, and a water outlet interval is formed between the water diversion plate 13 and the windward side a; the water outlet of the water inlet pipe 10 is positioned above the water diversion plate 13.

In the process that the water inlet pipe 10 injects water into the condensation air duct 1, the water output from the water inlet pipe 10 falls onto the water diversion plate 13, and the water diversion plate 13 is transversely arranged along the width direction of the windward side A, so that the water can be distributed along the width direction of the windward side A and overflows the water diversion plate 13 to flow onto the windward side A. Thus, the windward side A can be cleaned completely by water in the width direction, so that thread scraps adhered to the windward side A can be effectively cleaned.

In another embodiment, the water diversion plate 13 is located above the air inlet 11, and a water tank is formed between the water diversion plate 13 and the inner wall of the condensation air duct 1. Specifically, the water diversion plate 13 extends obliquely upward and forms a water channel with the inner wall of the condensation air duct 1, and water output by the water inlet pipe 10 can be more conveniently guided to be distributed along the width direction of the windward side a by the water channel.

In a preferred embodiment, a folded edge 131 folded downwards is arranged on the water diversion plate 13, and the water outlet interval is formed between the folded edge 131 and the windward side a. Specifically, the edge of the water diversion plate 13 close to the windward side a is formed with a folded edge 131 which is bent downwards, and the folded edge 131 can guide the water overflowing from the edge of the water diversion plate 13, so that the water can flow more smoothly on the windward side a.

Similarly, in another embodiment, the water inlet pipe 10 may be used to wash the thread scraps with water flow on the windward side a, or may be used to spray water directly on the windward side a. Namely, the water outlet of the water inlet pipe 10 extends to the interior of the condensation air duct 1, and the water outlet of the water inlet pipe 10 sprays water towards the windward side a. Specifically, the water output from the water inlet pipe 10 is directly sprayed towards the windward side a, and the thread scraps on the windward side a are cleaned by the impact of the water flow.

In the actual use process, the water supply mode of the water inlet pipe 10 may be a water supply module in the washing and drying machine, or a separate water inlet valve may be configured to be connected with a water pipe in a home to supply water independently to the water inlet pipe 10, which is not limited herein. When the water inlet pipe 10 is actually used, before clothes drying, water can be injected into the condensation air duct 1 through the water inlet pipe 10 so as to form water with a certain liquid level height in the water storage area 103, and condensation and thread scrap removal are achieved. Generally, the height of the water level in the water storage area 103 will not exceed the lower edge of the air inlet 11, and meanwhile, for the control of the height of the water level in the water storage area 103, a manner of configuring an overflow port in the conventional technology may be adopted, which is not limited or described herein. In addition, after the clothes are dried, the water in the water storage area 103 can be discharged through the drain pipe 14 arranged at the bottom of the condensation air duct 1, and the drain pipe 14 can be provided with an electric control valve to realize the automatic control of the opening and closing of the drain pipe.

In some embodiments, for better lint removal, the lint removal module 300 further includes a first wind deflector 2 and a second wind deflector 3.

First deep bead 2 sets up in condensation wind channel 1 and extends downwards from the top in condensation wind channel 1, and second deep bead 3 sets up in condensation wind channel 1 and extends upwards from the below of condensation wind channel 1. Wherein, along the inside air current direction in condensation wind channel 1, first deep bead 2 and second deep bead 3 arrange in proper order in one side of air intake 11 to make the lower tip of first deep bead 2 be located the front side of the upper end of second deep bead 3, form air inlet area 101 between first deep bead 2, second deep bead 3 and the air intake 11, form air-out district 102 between first deep bead 2, second deep bead 3 and the air outlet 12. In addition, the bottom of the condensation air duct 1 forms a water storage area 103, the air inlet 11 is higher than the water storage area 103, and the second air baffle 3 is located in the water storage area 103.

In the practical use process, before the clothes drying process of the washing and drying machine, a certain amount of water needs to be injected into the condensation air duct 1 through the water inlet pipe 10, so as to condense the damp and hot air and clean the thread scraps in the damp and hot air by using the water in the condensation air duct 1. After the water storage area 103 is filled with water, the water level of the water in the condensation air duct 1 needs to submerge the lower end of the first wind shield 2 when the washing and drying machine does not start the drying operation. In this way, the air inlet area 101 and the air outlet area 102 can be separated by the first wind screen 2 and the water in the condensation duct 1.

After the drying operation is started, the damp air flow output from the tub 100 enters the lint removal module 300. The air flow with the thread scraps output from the washing tub 100 enters the air inlet area 101 in the condensation air duct 1 through the air inlet 11, and since the air inlet area 101 and the air outlet area 102 are spaced apart by the first wind deflector 2 inserted in the water, the water in the air inlet area 101 is pressed into the air outlet area 102 under the action of the air pressure, and finally, the air flow enters between the first wind deflector 2 and the second wind deflector 3 through the bottom of the first wind deflector 2.

When the air current flows through the surface of the first wind shield 2, the air current is fully contacted with the water layer on the surface of the first wind shield 2 to achieve the effect of absorbing the thread scraps. Meanwhile, under the action of the airflow, water will impact the surface of the second wind deflector 3, so that a large-scale splash of water will be formed on the upper portion of the second wind deflector 3. And the air current flowing between the first wind deflector 2 and the second wind deflector 3 is further cleaned by the generated splash, so that the aim of efficiently removing the thread scraps in the air current can be achieved.

After the air flow output from the tub 100 is condensed and lint-removed, the air flow enters the air inlet of the drying module 200 through the air outlet 12 of the lint-removing module 300, and then flows into the drying module 200 to form a high-temperature drying air flow, and then flows into the tub 100 through the air inlet of the drying module 200 to dry the laundry in the tub 100, thereby completing one cycle of the air flow. The control airflow is repeatedly circulated among the tub 100, the lint removal module 300, and the drying module 200 until the laundry in the tub 100 is dried. Therefore, the washing and drying machine can synchronously realize the function of removing the thread scraps through the thread scraps removing module 300 in the process of drying clothes.

In a preferred embodiment, the lower end of the first wind deflector 2 and the upper end of the second wind deflector 3 may form a projected overlapping area in the horizontal projection direction. Specifically, the lower end of the first wind deflector 2 is lower than the upper end of the second wind deflector 3 in height, so that the lower end of the first wind deflector 2 and the upper end of the second wind deflector 3 have a projection overlapping region in the horizontal projection direction, and after bypassing the bottom of the first wind deflector 2, the air flow can be further guided by the second wind deflector 3 to flow. In this way, it is ensured that the air flow can flow between the first wind deflector 2 and the second wind deflector 3 and into the wind-out zone 102.

And the air current flows between first deep bead 2 and second deep bead 3, can make the air current remove the line bits with the water layer contact on first deep bead 2 and second deep bead 3 surface fully on the one hand, on the other hand also can ensure that the air current rises the in-process and can fully contact with the splash that second deep bead 3 produced to improve the efficiency of removing the line bits effectively.

In another embodiment, in order to better optimize the effect of removing the thread scraps, the lower end portion of the first wind deflector 2 is preferably bent toward the second wind deflector 3. Specifically, the air current will flow towards the direction of second deep bead 3 after the lower tip direction of first deep bead 2, can make the further flow of leading of air current via second deep bead 3 remove the line bits on the one hand, and on the other hand, when the air current flows up along second deep bead 3, can also form wider splash to the further impact of the water layer of top.

Similarly, the upper end of the second wind deflector 3 is bent in the direction of the first wind deflector 2. Specifically, after being guided by the upper end portion of the second wind deflector 3, the airflow flows towards the first wind deflector 2, so that the airflow can be transmitted back to the first wind deflector 2 again to flow in a guiding manner, and the water layer on the surface of the first wind deflector 2 is fully utilized to remove the thread scraps.

More preferably, the lower end of the first wind deflector 2 and the upper end of the second wind deflector 3 are both bent.

In some embodiments, a wind guiding portion 21 extending toward the wind outlet area 102 may be further disposed on the upper portion of the first wind deflector 2, and the wind guiding portion 21 is located above the second wind deflector 3 and is further away from the wind inlet area 101 than the second wind deflector 3. Specifically, in the process that the air flow passes through the lower end part of the first wind deflector 2 and continues to flow upwards along the first wind deflector 2, the air flow is shielded and guided by the air guide part 21 on the upper part, so that the retention time of the air flow in the condensation air duct 1 is prolonged, the air flow is fully contacted with water to perform the wire scrap removing operation, and the wire scrap removing efficiency is effectively improved. The air guiding portion 21 is preferably designed to extend obliquely downward, so that the air guiding portion 21 can guide the air flow to flow toward the water surface at the bottom again, and the air flow can impact the water surface behind the second wind deflector 3 again to remove the thread scraps.

In addition, there are various forms for the specific structures of the first wind deflector 2 and the second wind deflector 3. For example: the first wind deflector 2, the second wind deflector 3, and the wind guide portion 21 may be configured to have an arc-shaped configuration. In this way, the airflow flowing between the lower end of the first wind deflector 2 and the upper end of the second wind deflector 3 can form a vortex to sufficiently contact with water to improve the effect of removing lint; meanwhile, the air guide part 21 above the second wind deflector 3 can form vortex air flow by guiding the air flow, so as to further optimize the effect of removing the thread scraps.

In order to reduce the amount of water mist overflowing from the outlet 12, at least one water baffle (not shown) is preferably disposed inside the condensation duct 1 and below the outlet 12. Specifically, the breakwater is located the below of air outlet 12, and the rising in-process of air current shelters from via the breakwater, can block the water smoke in the air current and the water droplet that mingles with to reduce the water smoke volume that enters into in the dry clothing module 200, and then improve dry clothing efficiency. When a plurality of water baffles are arranged, the plurality of water baffles are arranged at intervals up and down and are arranged in a transversely staggered mode.

In the embodiment, the specific structural form of the washing and drying machine is not limited herein, and for the lint removing module, the lint removing module may be built inside the air duct of the washing and drying machine to maintain the overall aesthetic property of the washing and drying machine.

The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions.
