[0033] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

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

[0035] like Figure 1-Figure 3 As shown, this embodiment proposes a washing and drying machine. In order to meet the washing requirements, the outer barrel 100, the inner barrel 200 and the motor (not shown) are configured in the outer shell 100 of the washing and drying machine. During the washing process, the motor drives the inner barrel 200 to rotate in the outer barrel 100 to achieve the washing process of the clothes. In order to dry the clothes in the inner barrel 200, a drying module 300 and a condensing module 400 are configured accordingly. The drying module 300 generally includes a drying air duct 301, a heater 302 and a fan 303. The fan 303 can drive the gas flow so that the air in the outer barrel 100 circulates and flows into the drying air duct 301, and the heater 302 is powered on to generate heat to dry the airflow flowing through the drying air duct 301. As for the condensing module 400, it mainly condenses and removes the lint from the air output from the outer barrel 100.

[0036] Specifically, the air output from the outer tub 100 is processed by the condensing module 400 and then enters the drying air duct 301, and then flows into the outer tub 100 after being heated by the drying module 300, so as to dry the clothes in the outer tub 100, thereby completing one cycle of the airflow. The airflow is controlled to circulate repeatedly between the outer tub 100, the condensing module 400 and the drying module 300 until the clothes in the outer tub 100 are dried.

[0037] On the premise of meeting the requirements of condensation and lint removal, in order to meet the requirements of compact structure design, the condensation module 400 includes a condensation water tank 1. The bottom of the condensation water tank 1 forms a water storage area (not marked); wherein the condensation water tank 1 is arranged at the rear end of the outer barrel 100 and the condensation water tank 1 has an extension cavity extending from the lower part of the outer barrel 100 toward the front end of the outer barrel 100; the air in the outer barrel 100 enters the condensation water tank 1, condenses the lint through the water in the water storage area, and then enters the drying air duct 301 for heating and drying before entering the outer barrel 100.

[0038] Specifically, the condensation water tank 1 is arranged on the back of the outer barrel 100. At the same time, part of the condensation water tank 1 is also extended on the outer wall of the outer barrel 100 to form an extended cavity. In this way, the extended cavity can be used to increase the volume of the water storage area to increase the contact area between cold water and air, thereby meeting the requirements of air condensation and lint removal.

[0039] Since the condensation water tank 1 is mostly distributed on the outer wall of the outer barrel 100, the air space between the outer barrel 100 and the outer shell 1000 is fully utilized to accommodate the condensation water tank 1. The overall thickness of the condensation water tank 1 at the end of the outer barrel 100 can be designed to be thinner, as long as the outer barrel 100 can normally output air to the condensation water tank 1, thereby realizing a compact design of the internal structure of the outer shell 1000.

[0040] The condensation water tank 1 is connected between the outer tub 100 and the drying module 300. The humid air in the outer tub 100 enters the condensation water tank 1. After the air contacts the cold water in the water storage area of ​​the condensation water tank 1 and is condensed and the lint is removed, the air is output to the drying module 300 for air drying and heating. Then, the high-temperature dry air is transported to the outer tub 100 to achieve drying of the clothes. As for the specific performance entity of the drying module 300, the drying structure in the washing and drying machine in the conventional technology can be adopted, which is not limited or elaborated here.

[0041] In some embodiments, the condensation water tank 1 is located at the bottom of the outer tub 100 and is offset to one side of the outer tub 100. Specifically, the condensation water tank 1 is located at one of the bottom corners of the outer tub 100 and the outer shell, so that the free space between the outer tub 100 and one of the bottom corners of the outer shell can be repeatedly used to install a sufficiently large condensation water tank 1, which is more conducive to the requirement of compact overall structural design.

[0042] In other embodiments, for the convenience of assembly, an air outlet 1001 is provided at the bottom of the outer barrel 100, and the air outlet 1001 is connected to the condensed water tank 1. Specifically, in the actual assembly process, the condensed water tank 1 is installed on the end surface of the outer barrel 100 and is connected to the air outlet 1001 at the same time, so that the air in the outer barrel 100 enters the condensed water tank 1 through the air outlet 1001.

[0043] In one embodiment, the condensation module 400 further includes: a partition 4, which is arranged in the condensation water tank 1, and the partition 4 divides the condensation water tank 1 into an air intake area 101 and an exhaust area 102; wherein the air outlet 1001 is connected to the air intake area. Specifically, by setting the partition 4, the condensation water tank 1 is divided into an air intake area 101 and an exhaust area 102 by the partition 4. The air output from the outer barrel 100 first enters the air intake area 101, and the air is blocked by the partition 4 to more effectively contact the cold water in the bottom water storage area, thereby better playing the role of condensation and lint removal. Finally, the air passes over the partition 4 and enters the exhaust area 102, and the air in the exhaust area 102 that has been processed by condensation and lint removal enters the drying air duct 301.

[0044] In some embodiments, the outer barrel 100 is usually provided with a first drain pipe 1002 to drain the water inside. Correspondingly, the outer shell 1000 is also provided with a drain assembly 500, which includes: a drain pump 501 and a drain pipe 502, the drain pump is provided with a water inlet and a water outlet, and the drain pump is provided in the outer shell; one end of the drain pipe is connected to the water outlet of the drain pump, and the other end of the drain pipe extends outward to the outside of the outer shell; after starting the drain pump 501, the water in the outer barrel 100 can be drained. At the same time, the condensation water tank 1 is also provided with a second drain pipe 11, and the condensation water tank 1 is also provided with an overflow pipe 12. After the drying operation is completed, the second drain pipe 11 can be opened to drain the water in the condensation water tank 1 into the drain pump 501, and the water is discharged through the drain pump 501; at the same time, when there is too much water in the condensation water tank 1, the excess water overflows from the overflow pipe 12, and then the overflow water is also discharged through the drain pump 501.

[0045] In addition, in the present embodiment, a water inlet pipe (not shown) is further provided on the condensate water tank 1, through which water can be filled into the condensate water tank 1, and the water inlet pipe can complete the water inlet operation through the water inlet mechanism of the washing and drying machine, and the second drain pipe 11 can be switched on and off by configuring a valve. There is no restriction on the water inlet method of the water inlet pipe and the switching method of the second drain pipe 11.

[0046] In addition, the outer barrel 100 and the condensation water tank 1 can be assembled in a split structure or an integrated structure. That is, the outer barrel 100 and the condensation water tank 1 are split structures, and the condensation water tank 1 can be installed on the outer barrel 100 by screw fastening or clamping. Alternatively, the condensation water tank 1 is formed integrally on the outer barrel 100, for example, 3D printing can be used to form an integral condensation water tank 1 on the outer barrel 100.

[0047] In a preferred embodiment, in order to improve the efficiency of removing the wire scraps, the condensation water tank 1 is further provided with a first baffle 2 and a second baffle 3. The first baffle 2 is located in the extension cavity and extends from the upper side of the condensation water tank 1 to the lower side, and the second baffle 3 is located in the extension cavity and extends from the lower side of the condensation water tank 1 to the upper side. In addition, along the airflow direction inside the condensation water tank 1, the lower end of the first baffle 2 is located in front of the upper end of the second baffle 3, and an air inlet area 101 is formed between the first baffle 2, the second baffle 3, the partition 4 and the air inlet 11, and an exhaust area 102 is formed between the first baffle 2, the second baffle 3, the partition 4 and the air outlet 12.

[0048] During the drying process, a certain amount of water needs to be injected into the condensation water tank 1, and the water is stored in the water storage area, so that the water in the water storage area can be used to clean the lint. In the case where the drying module is not started, the water level in the condensation water tank 1 needs to submerge the lower end of the first baffle 2. In this way, the air inlet area 101 and the exhaust area 102 can be isolated by the first baffle 2 and the water in the water storage area.

[0049] After the drying module 300 is started, the airflow carrying lint outputted from the outer barrel 100 enters the air inlet area 101 in the condensed water tank 1 through the air inlet 1001. Since the air inlet area 101 and the exhaust area 102 are separated by the first baffle 2 inserted in the water, the water in the air inlet area 101 is pressed into the exhaust area 102 under the action of air pressure, and finally, the airflow enters between the first baffle 2 and the second baffle 3 through the bottom of the first baffle 2. When the airflow flows over the surface of the first baffle 2, the airflow fully contacts the water layer on the surface of the first baffle 2 to achieve the effect of absorbing lint.

[0050] At the same time, under the action of the airflow, water will impact the surface of the second baffle 3, thereby forming a large range of water splashes on the upper part of the second baffle 3. The airflow flowing between the first baffle 2 and the second baffle 3 will be further cleaned by the generated water splashes, thereby achieving the purpose of efficiently removing the lint in the airflow.

[0051] Preferably, along the horizontal projection direction, the lower end of the first baffle 2 and the upper end of the second baffle 3 form a projection overlap area. Specifically, the lower end of the first baffle 2 is lower than the upper end of the second baffle 3 in height, so that the lower end of the first baffle 2 and the upper end of the second baffle 3 have a projection overlap area in the lateral projection direction, so that after the airflow bypasses the bottom of the first baffle 2, it can be further guided by the second baffle 3. In this way, it can be ensured that the airflow can flow between the first baffle 2 and the second baffle 3 and enter the exhaust area 102. The airflow flows between the first baffle 2 and the second baffle 3. On the one hand, the airflow can fully contact the water layer on the surface of the first baffle 2 and the second baffle 3 to remove the wire scraps. On the other hand, it can also ensure that the airflow can fully contact the water splashes generated by the second baffle 3 during the rising process, so as to effectively improve the efficiency of wire scrap removal.

[0052] When the overflow pipe 12 is arranged on the condensation water tank 1 , in order to ensure that the lower end of the first baffle plate 2 can be submerged below the water surface, the lower edge height of the first baffle plate 2 should be arranged to be lower than the height of the overflow pipe 12 .

[0053] In order to better optimize the effect of removing the wire scraps, in this embodiment, the lower end of the first baffle 2 is preferably bent toward the direction of the second baffle 3. Specifically, after the airflow is guided by the lower end of the first baffle 2, it will flow toward the direction of the second baffle 3. On the one hand, the airflow can be further guided to flow through the second baffle 3 to remove the wire scraps. On the other hand, while the airflow flows upward along the second baffle 3, it can also further impact the water layer above to form a larger range of water splashes.

[0054] Similarly, the upper end of the second baffle plate 3 is bent toward the direction of the first baffle plate 2. Specifically, the airflow guided by the second baffle plate 3 will flow toward the direction of the first baffle plate 2 after being guided by its upper end, so that the airflow can be transferred back to the first baffle plate 2 to guide the flow, so as to make full use of the water layer on the surface of the first baffle plate 2 to remove the wire scraps.

[0055] A more preferred solution is that the lower end of the first baffle 2 and the upper end of the second baffle 3 are both bent.

[0056] In some embodiments, an air guide 21 extending toward the exhaust area 102 may be provided on the upper portion of the first baffle 2. The air guide 21 is located above the second baffle 3 and further away from the air inlet area 101 than the second baffle 3. Specifically, in the process of the airflow passing over the lower end of the first baffle 2 and continuing to flow upward along the first baffle 2, the airflow will be shielded and guided by the upper air guide 21 to extend the retention time of the airflow in the condensate water tank 1, so as to achieve full contact between the airflow and the water for the wire scrap removal operation, so as to effectively improve the efficiency of the wire scrap removal. The air guide 21 is preferably designed to extend obliquely downward, so that the airflow can be guided to flow toward the water surface at the bottom again through the air guide 21, so that the airflow hits the water surface behind the second baffle 3 again for wire scrap removal.

[0057] In addition, there are many forms for the specific structure of the first baffle 2 and the second baffle 3. For example, the first baffle 2, the second baffle 3 and the air guide 21 can all be designed as arc structures, or can all be designed as bent arc structures; in this way, the airflow flowing between the lower end of the first baffle 2 and the upper end of the second baffle 3 can form a vortex to fully contact with water to improve the effect of removing wire scraps; at the same time, the air guide 21 located above the second baffle 3 can form a vortex airflow by guiding the airflow to further optimize the effect of removing wire scraps. Similarly, the first baffle 2 and the second baffle 3 are also set as folded edge structures to achieve blocking and guiding of the airflow.

[0058] 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.
