Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0033] Embodiment 1, as Figure 1-Figure 5 As shown, this embodiment proposes a condensation and lint removal mechanism, comprising a housing 1 and an upper windshield assembly 2 and a lower windshield assembly 3 arranged in the housing 1. The housing 1 is provided with an air inlet 11 and an air outlet 12. When in use, a certain amount of water is injected into the housing 1 to condense the inflowing air and remove lint.

[0034] In actual use, the condensing lint removal mechanism is installed in the housing of the washing and drying machine, such as Figure 7As shown, the washing and drying machine is usually equipped with an outer barrel 100 and a drying module 200, wherein the drying module 200 is used to transport dry air into the outer barrel 100 and inhale the humid air in the outer barrel 100 to achieve air circulation, and the shell 1 in the condensation and lint removal mechanism is connected between the outer barrel 100 and the drying module 200, and the humid air in the outer barrel 100 enters the shell 1 through the air inlet 11, and after the lint removal treatment, it is output to the drying module 200 through the air outlet 12 for air drying and heating, and then the high-temperature dry air is transported to the outer barrel 100 to achieve the drying treatment of the clothes.

[0035] As for the specific entity of the drying module 200, the drying structure of the washing and drying machine in the conventional technology can be adopted, which will not be limited or elaborated here.

[0036] Among them, the upper wind shield assembly 2 and the lower wind shield assembly 3 configured in the shell 1 are used to guide the air flow to increase the contact area between air and water. The specific structural forms of the upper wind shield assembly 2 and the lower wind shield assembly 3 are explained in conjunction with the accompanying drawings.

[0037] The upper windshield assembly 2 is provided with two upper windshield plates 21 and a top plate 22 arranged opposite to each other. The upper windshield plates 21 are arranged in the housing 1 and extend downward from the upper side of the housing 1, and the top plate 22 is arranged in the housing 1 and connected between the tops of the two upper windshield plates 21.

[0038] The lower wind shield assembly 3 is provided with two lower wind shield plates 31 which are arranged opposite to each other. The lower wind shield plates 31 are disposed in the housing 1 and extend from the bottom to the top of the housing 1 .

[0039] The lower end of the upper wind shield 21 is located between the upper ends of the two lower wind shields 31 , the air inlet is located between the two upper wind shields 21 and the top plate 22 , and the air outlet is located on the outside of the upper wind shield 21 or the top plate 22 .

[0040] Before the clothes drying operation, water is first injected into the housing 1, and when the clothes drying module 200 is not started, the water level in the housing 1 needs to submerge the lower end of the upper wind shield 21. In this way, the upper wind shield 21, the top plate 22, the lower wind shield, and the water in the housing 1 can separate the air inlet 11 from the air outlet 12. In this way, an air inlet area 101 can be formed inside the housing 1 between the air inlet and the inner walls of the two upper wind shields 21 and the inner wall of the top plate 22, and an air outlet area 102 can be formed between the air outlet and the outer walls of the two upper wind shields 21 and the outer wall of the top plate 22.

[0041] In the process before the clothes drying operation, the air output from the outer barrel 100 first enters the outer shell 1 through the air inlet 11. The air entering through the air inlet 11 is temporarily stored between the two upper wind shields 21 and the top plate 22 due to the blockage of the bottom water surface. As the air pressure between the upper wind shield 21 and the top plate 22 continues to increase, the water in the air inlet area 101 is pressed into the air outlet area 102 under the action of the air pressure; finally, the airflow enters between the upper wind shield 21 and the lower wind shield 31 through the bottom of the upper wind shield 21.

[0042] Along the airflow direction inside the housing 1, the lower end of the upper windshield 21 is located in front of the upper end of the lower windshield 31 on the corresponding side. When the airflow flows over the surface of the upper windshield 21, the airflow fully contacts the water layer on the surface of the upper windshield 21 to absorb the lint. Under the action of the airflow, water will impact the surface of the lower windshield 31, thereby forming a large range of water splashes on the upper part of the lower windshield 31. The airflow flowing between the upper windshield 21 and the lower windshield 31 will be further cleaned by the generated water splashes, thereby achieving the purpose of efficiently removing lint in the airflow.

[0043] At the same time, since the upper wind shield 21 and the lower wind shield 31 are arranged in pairs on both sides of the air inlet 11, the air can pass through the areas between the upper wind shield 21 and the lower wind shield 31 on both sides respectively, so that the air can be condensed and the lint removal can be achieved more quickly and efficiently, thereby meeting the drying requirements for large items such as clothing and bedding, and is more conducive to improving the user experience.

[0044] In some embodiments, along the transverse projection direction of the housing 1, the lower end of the upper wind shield 21 and the upper end of the lower wind shield 31 can form a projection overlap area. Specifically, in the height direction, the lower end of the upper wind shield 21 is lower than the upper end of the lower wind shield 31, so that the lower end of the upper wind shield 21 and the upper end of the lower wind shield 31 have a projection overlap area in the transverse projection direction, and the airflow can be further guided by the lower wind shield 31 after bypassing the bottom of the upper wind shield 21. In this way, it can be ensured that the airflow can flow between the upper wind shield 21 and the lower wind shield 31 and enter the air outlet area 102. The airflow flows between the upper wind shield 21 and the lower wind shield 31. On the one hand, the airflow can fully contact the water layer on the surface of the upper wind shield 21 and the lower wind shield 31 to remove the wire scraps, and on the other hand, it can also ensure that the airflow can fully contact the water splashes generated by the lower wind shield 31 during the rising process, so as to effectively improve the efficiency of removing the wire scraps.

[0045] In another embodiment, the air outlet is arranged above the top plate 22, that is, the air outlet is arranged on the top of the housing 1. Figure 6As shown, in order to reduce the amount of water mist overflowing from the air outlet 12, it is preferred that water retaining portions 221 extending outward are provided at both ends of the top plate 22, and the two water retaining portions 221 are distributed on both sides of the air outlet. Specifically, the water retaining portions 221 are located below the air outlet 12 and distributed on both sides of the air outlet 12. The water retaining portions 221 are shielded during the rising process of the airflow, and the water mist and mixed water droplets in the airflow can be blocked, so as to reduce the amount of water mist entering the clothes drying module 200, thereby improving the clothes drying efficiency.

[0046] In order to better optimize the effect of removing the wire scraps, in this embodiment, the lower end of the upper wind shield 21 is preferably bent toward the lower wind shield 31 on the corresponding side. Specifically, after the airflow is guided by the lower end of the upper wind shield 21, it will flow toward the lower wind shield 31. On the one hand, the airflow can be further guided to flow through the lower wind shield 31 to remove the wire scraps. On the other hand, while the airflow flows upward along the lower wind shield 31, it can also further impact the water layer above to form a larger range of water splashes.

[0047] Similarly, the upper end of the lower wind shield 31 is bent toward the upper wind shield 21 on the corresponding side. Specifically, the airflow guided by the lower wind shield 31 will flow toward the upper wind shield 21 after being guided by its upper end, so that the airflow can be reversed to the upper wind shield 21 to guide the flow, so as to make full use of the water layer on the surface of the upper wind shield 21 to remove the wire scraps.

[0048] A more preferred solution is that the lower end of the upper wind shield plate 21 and the upper end of the lower wind shield plate 31 are both bent.

[0049] In some embodiments, an air guide 211 extending toward the outer side of the upper wind shield 21 may be provided on the upper part of the upper wind shield 21, and the air guide 211 is located above the lower wind shield 31 at the corresponding side position, and is further away from the air inlet area 101 relative to the lower wind shield 31. Specifically, in the process of the airflow passing over the lower end of the upper wind shield 21 and continuing to flow upward along the upper wind shield 21, the airflow will be shielded and guided by the upper air guide 211 to extend the retention time of the airflow in the housing 1, so that the airflow can fully contact with the water to remove the wire scraps, so as to effectively improve the efficiency of the wire scraps removal. The preferred design is that the air guide 211 extends obliquely downward, so that the airflow can be guided to flow toward the water surface at the bottom again through the air guide 211, so that the airflow hits the water surface behind the lower wind shield 31 again to remove the wire scraps.

[0050] In one embodiment, the housing 1 of the condensing lint removal mechanism is further provided with a water inlet 13, and the bottom of the housing 1 is further provided with a switchable drain port 14, through which water can be injected into the housing 1, and the drain port 14 can be used to drain the water in the housing 1 to replace it with new water. The water inlet 13 can be operated by the water inlet mechanism of the washing and drying machine, and the drain port 14 can be controlled by configuring a valve, and the water inlet method of the water inlet 13 and the switch method of the drain port 14 are not limited.

[0051] In another embodiment, an overflow port 15 may be provided on the housing 1 to discharge excess water in the housing 1 through the overflow port 15. In order to prevent air from leaking out through the overflow port 15, the condensation and lint removal mechanism further includes a water seal box 4, on which a water outlet 41 is provided, and the water seal box is arranged outside the housing 1; an overflow pipe 5 is also provided on the housing 1, and the overflow pipe 5 is connected to the overflow port 15, and the free end of the overflow pipe extends into the water seal box. Specifically, a certain amount of water is stored in the water seal box 4 to immerse the free end of the overflow pipe, so that the air in the housing 1 will not leak out through the overflow port 15. The height position of the port at the free end of the overflow pipe is designed to be lower than the height of the water outlet. As for the housing 1, it is equipped with two overflow ports, which are located on the outer side of the lower windshield plate 31 on the corresponding side, and each overflow port is provided with an overflow pipe. In actual use, overflow is performed through the overflow ports on both sides respectively to ensure that the water levels of the lower wind shields 31 on both sides remain substantially consistent.

[0052] Embodiment 2, as Figure 7As shown, this embodiment proposes a washing and drying machine, including an outer barrel 100 and a drying module 200, and also includes the condensation lint removal mechanism described in the above embodiment 1. The drying module 200 has an air blowing port and an air suction port, the air blowing port is connected to the outer barrel 100, the air inlet 11 of the condensation lint removal mechanism is connected to the outer barrel 100, and the air outlet 12 of the condensation lint removal mechanism is connected to the air suction port of the drying module 200. When the washing and drying machine is in the drying operation, the drying module 200 extracts humid airflow from the outer barrel 100, and first enters the condensation and lint removal mechanism through the air inlet 11 to remove the lint in the airflow; then, the humid airflow with the lint removed enters the air intake of the drying module 200 through the air outlet 12 of the condensation and lint removal mechanism, and then flows into the drying module 200 to form a high-temperature dry airflow, and then flows into the outer barrel 100 through the air outlet of the drying module 200 to dry the clothes in the outer barrel 100, thereby completing one cycle of the airflow. The airflow is controlled to circulate repeatedly between the outer barrel 100, the condensation and lint removal mechanism, and the drying module 200 until the clothes in the outer barrel 100 are dried. In this way, the washing and drying machine of this embodiment can simultaneously realize the function of removing lint during the drying process.

[0053] In this embodiment, the specific structural form of the washing and drying machine is not limited here, and the condensation lint removal mechanism can be built into the shell of the washing and drying machine to maintain the overall aesthetics of the washing and drying machine.

[0054] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for a person skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to replace some of the technical features therein by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions claimed to be protected by the present invention.
