Those skilled in the art will understand that words such as "first" and "second" do not limit the quantity or order of execution, and words such as "first" and "second" do not necessarily limit differences. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0030] The existing rear duct condensation method causes water waste during use. The utility model provides a condensation duct assembly that optimizes the removal of water vapor in the drying airflow without affecting the original structure of clothing processing equipment with drying function, such as a condensing washer-dryer, so as to avoid the waste of water resources. Specifically, the utility model increases the contact area between the airflow and the cooling water by adding a breaking structure 2 in the shell 1. The water vapor in the airflow is more easily condensed by the cooling water, and the cooling water can also condense more water vapor in the airflow, thereby avoiding the waste of water resources and improving the user experience.

[0031] According to the first aspect of the embodiment of the present application, Figures 1 to 5 As shown, a condensation duct assembly is provided, including a shell 1, a condensation structure and a dispersion structure 2. An air duct 11 is formed in the shell 1, and an air inlet 12 and an air outlet 13 are provided on the shell 1 for air flow contact heat exchange to condense and dehumidify the air flow; and the dispersion structure 2 is arranged in the air duct 11, and is used to disperse the cooling water when the cooling water flows in the air duct 11.

[0032] Through the above technical solution, when the airflow enters the air duct 11 through the air inlet 12 and when the cooling water flows in the air duct 11, the cooling water will be dispersed by the dispersion structure 2, increasing the contact area between the cooling water and the airflow in the air duct 11, and indirectly increasing the contact area between the water vapor in the airflow and the cooling water, making it easier for the water vapor in the airflow to be condensed by the cooling water, and the cooling water can also condense more water vapor in the airflow. In this way, when gas dehumidification is applied to a condensing washer-dryer and the cooling water is condensed water, when removing the water vapor in the drying airflow, the dispersion structure 2 is used to disperse the condensed water, so that the water vapor in the drying airflow is more easily condensed by the condensed water through heat exchange, and the condensed water can also condense more water vapor in the airflow, thereby reducing the consumption of condensed water and further saving water resources. At the same time, because the dispersion structure 2 is arranged in the air duct 11, for example, when the flow direction of the cooling water is opposite to that of the gas, the dispersion structure 2 can also play an interception role, preventing the airflow from driving the cooling water out of the housing 1.

[0033] It should be noted that the breaking up mentioned above and below is essentially a description of the liquid state. After the cooling water is broken up, multiple water droplets will appear to spread outward.

[0034] When drying clothes, the drying airflow evaporates the moisture on the clothes into water vapor, and the drying airflow drives the water vapor away from the clothes. When the condensing air duct assembly in the present application is in use, due to the high temperature of the drying airflow and water vapor, when the drying airflow and water vapor come into contact with the cooling water at a lower temperature, the water vapor in the airflow will be cooled and condensed into liquid water, mixed with the cooling water, and thus separated from the drying airflow, achieving dehumidification of the drying airflow. It should be noted that when gas dehumidification is applied to a condensing washer-dryer, generally speaking, tap water can be selected as the cooling water. The temperature of tap water is lower than the temperature of the drying airflow, and it is also easy to obtain, which is more convenient for the use of the condensing air duct assembly.

[0035] At the same time, in the present application, the shape and size of the shell 1 and the air duct 11 can be adaptively designed according to the equipment to which the condensing air duct assembly is applied. For example, when the condensing air duct assembly is applied to a larger-sized dryer, the size of the shell 1 and the air duct 11 can also be adaptively increased, and the shape can also be adaptively designed according to the structure near the installation location.

[0036] In some embodiments, the scattering structure 2 may include an active member 21 movably disposed in the air duct 11, the active member 21 being configured such that: on the flow path of the cooling water, the active member 21 moves to actively contact the cooling water and scatter the cooling water; or, the scattering structure 2 includes a passive member 23 fixedly disposed in the air duct 11, the passive member 23 being configured such that: on the flow path of the cooling water, the cooling water flows and actively contacts the passive member 23, so that the passive member 23 scatters the cooling water. In this way, the scattering structure 2 actively scatters the cooling water through the active member 21, or the cooling water actively contacts the passive member 23, so that the cooling water is passively scattered. The design of the scattering structure 2 can be adaptively selected according to the application. As described above, when the dimensions of the housing 1 and the air duct 11 are designed to be larger, the scattering structure 2 can be the active member 21 disposed in the air duct 11, the active member 21 having a certain range of motion, which can cover more of the flow path of the cooling water, thus avoiding the scattering structure 2 from being too large and reducing the volume occupied by the scattering structure 2 in the air duct 11. When the size of the shell 1 and the air duct 11 is designed to be small, the space of the air duct 11 is limited and the active component 21 is not easy to move. At this time, the breaking up structure 2 can be selected as the passive component 23. Through the flow of cooling water, the cooling water contacts the passive component 23, so that the cooling water is passively broken up.

[0037] Taking the example of a breaking up structure 2 including an active member 21 movably arranged in the air duct 11, the active member 21 can be a first plate body, and the breaking up structure 2 also includes a driving member 22. The driving member 22 can be a swinging motor. The output shaft of the swinging motor is connected to the first plate body, and is used to drive the first plate body to swing in the air duct 11, so that the first plate body actively contacts the cooling water and breaks up the cooling water. In this way, the first plate body will continuously contact the cooling water during the continuous swinging process, and the impact force when the first plate body contacts the cooling water can break up the cooling water. At the same time, the swinging motor can be remotely controlled, which is more convenient for the use of the gas dehumidification device. In addition to being a swinging motor, the driving member 22 can also be a rotating motor. The first plate body is connected to the output shaft of the rotating motor. The rotating motor drives the first plate body to rotate. The first plate body will also continuously contact the cooling water during the rotation process.

[0038] Taking the example of the scattered structure 2 including a passive member 23 fixedly arranged in the air duct 11, the passive member 23 can be a second plate body arranged on the flow path of the cooling water, and a plurality of through holes 24 for gas and liquid circulation are opened on the second plate body. Figure 2 and Figure 4. When the cooling water flows through the second plate body, the cooling water will contact the second plate body and generate an impact force, which causes the cooling water to be scattered. The scattered cooling water will flow out from the through hole 24, and the airflow of the air duct 11 will also pass through the through hole 24 when passing through the second plate body. When the airflow and cooling water pass through the through hole 24 respectively, the airflow and cooling water can be fully contacted, thereby improving the dehumidification effect. At the same time, the second plate body can also play an intercepting role, slowing down the flow speed of the airflow and cooling water, so that the airflow and cooling water can have sufficient time to contact, further improving the dehumidification effect.

[0039] To prevent the second plate from slowing down the flow of air and cooling water, in some embodiments, the edges of the ends of the through-holes 24 may be provided with chamfers 25 for guiding the flow. The chamfers 25 can guide the flow of air and cooling water, facilitating their passage through the second plate.

[0040] In some embodiments, the condensation structure may further include a water inlet device, a water outlet device, and a liquid inlet 3 and a liquid outlet 4 opened on the shell 1, the liquid inlet 3 being connected to the water inlet device and the air duct 11 respectively, and the liquid outlet 4 being connected to the water outlet device and the air duct 11 respectively, the liquid inlet 3 being arranged above the liquid outlet 4, and the cooling water being discharged from the liquid outlet 4; the water inlet device and / or the water outlet device may be controlled to adjust the water inlet flow rate and / or the water outlet flow rate according to the humidity and / or drying process of the air flow in the air duct 11. In this way, the cooling water entering the air duct 11 from the liquid inlet 3 can automatically flow from top to bottom and toward the liquid outlet 4 under the action of gravity, and the condensation air duct assembly no longer needs to be additionally provided with a driving structure to promote the flow of cooling water in the air duct 11, thereby reducing the cost of the condensation air duct assembly. The scattering structure 2 can be arranged between the liquid inlet 3 and the liquid outlet 4, so that when the cooling water flows from top to bottom, it can actively flow through the scattering structure 2 and be scattering. At the same time, liquid outlet 4 allows cooling water to continuously flow out, thus preventing the cooling water from heating up due to prolonged use within air duct 11 and ensuring effective cooling water use. Furthermore, the water inlet and / or outlet devices can be controlled to adjust the water inlet and / or outlet flow rates based on the humidity of the airflow in air duct 11 and / or the drying process. This ensures the cooling water flow rate within air duct 11 and prevents excessive or insufficient cooling water. For example, when the humidity of the airflow entering air duct 11 is high, the water inlet device can be controlled to increase the cooling water flow rate.

[0041] In this case, the air inlet 12 and the air outlet 13 can be spaced apart in the vertical direction. Taking the liquid inlet 3 being arranged above the liquid outlet 4 as an example, generally speaking, the air outlet 13 can be arranged above the air inlet 12. Taking the liquid inlet 3 being arranged above the liquid outlet 4 as an example, in this way, the flow direction of the cooling water is opposite to the flow direction of the air flow, and the cooling water is not easily carried out of the housing 1 by the air flow.

[0042] Furthermore, taking the aforementioned arrangement of the air outlet 13 above the air inlet 12 and the liquid inlet 3 above the liquid outlet 4 as an example, when the condensing washer-dryer is just beginning its drying cycle, the drying airflow is at a low temperature and carries relatively little moisture. Alternatively, as the drying cycle nears its end, much of the moisture in the clothing has already been dried, and the drying airflow carries relatively little moisture. In this case, less cooling water can be used to condense the drying airflow. Due to the low amount of cooling water, the water droplets formed after being dispersed by the dispersion structure 2 are smaller in volume and weight. These smaller droplets are then blown by the airflow, causing the cooling water to be carried out of the housing 1. Therefore, to further prevent the cooling water from being carried out of the housing 1 by the airflow, a guide groove 5 can be provided on the inner wall of the housing 1 to avoid the dispersion structure 2. One end of the guide groove 5 is connected to the liquid inlet 3, and is used to guide the cooling water and form a water film on the guide groove 5. A small amount of cooling water flowing within the guide groove 5 will aggregate to form a water film, thereby preventing the cooling water from being dispersed by the airflow and carried out of the housing 1 at low flow rates. When the flow rate of the cooling water is small, the cooling water can pass through the guide groove 5 instead of the breaking up structure 2 , thereby preventing the cooling water from being broken up and carried out of the housing 1 by the air flow.

[0043] When the flow rate of cooling water is large, the cooling water can actively overflow the guide groove 5, so that the cooling water can be dispersed through the dispersion structure 2. The guide groove 5 does not need to extend to the liquid outlet 4, which can shorten the distance of the guide groove 5 and facilitate the processing of the guide groove 5. When the guide groove 5 passes through the dispersion structure 2 and avoids the dispersion structure 2, it can avoid being dispersed when the cooling water flow rate is small. It should be noted that the above-mentioned cooling water flow rate is small, which is actually a relative concept and is described based on the maximum flow rate of cooling water. The size of the guide groove 5 can be designed according to the maximum flow rate of cooling water.

[0044] In some embodiments, a first humidity sensor and a second humidity sensor are further provided in the air duct 11. The first humidity sensor is provided in the air inlet 12, and the second humidity sensor is provided in the air outlet 13. A valve electrically connected to the first humidity sensor and the second humidity sensor, respectively, may be provided on the liquid inlet 3. The first humidity sensor is capable of detecting the humidity of the airflow that has not undergone dehumidification treatment. Based on the data detected by the first humidity sensor, the opening of the valve on the liquid inlet 3 can be controlled. When the data detected by the first humidity sensor is high, it indicates that there is more water vapor in the airflow. The opening of the valve can be increased to increase the flow rate of cooling water entering the air duct 11 from the liquid inlet 3. Conversely, when the data detected by the first humidity sensor is low, it indicates that there is less water vapor in the airflow. The opening of the valve can be reduced to reduce the flow rate of cooling water entering the air duct 11 from the liquid inlet 3. The second humidity sensor can detect the humidity of the air flow that has been dehumidified. According to the data detected by the second humidity sensor, the opening of the valve on the liquid inlet 3 can be controlled. When the data detected by the second humidity sensor is high, it means that the air flow that has been dehumidified still contains a lot of water vapor. At this time, the opening of the valve can be increased to increase the flow rate of cooling water entering the air duct 11 from the liquid inlet 3 to ensure the dehumidification effect of the air flow.

[0045] In some embodiments, the dehumidification assembly further includes a fan that can be connected to the air inlet 12 and the air outlet 13, respectively, and the fan is used to promote the flow of air in the air duct 11. This makes it easier for air to enter the air duct 11 and to flow out of the air duct 11, thereby preventing air from accumulating in the air duct 11 for too long and causing the air to reabsorb moisture.

[0046] According to the second aspect of the embodiment of the present application, a clothing processing device is provided, which is provided with a clothing processing drum 6 and a drying system connected to the clothing processing drum 6, the clothing processing drum 6 includes an outer drum and an inner drum, and the drying system is provided with a condensing air duct assembly of any of the above-mentioned embodiments and has all the beneficial effects of the above-mentioned condensing air duct assembly, which will not be repeated here. Specifically, the condensing air duct assembly provided by the present invention is arranged on a condensing washing and drying machine, and the effect is particularly significant. Taking the condensing air duct assembly provided by the present invention as an example of being arranged on a condensing washing and drying machine, the condensing air duct assembly can dehumidify the air flow after drying clothes. At this time, the air inlet of the above-mentioned condensing air duct assembly can be connected to the air outlet on the outer drum of the condensing washing and drying machine, and the air outlet of the above-mentioned condensing air duct assembly can be connected to the air inlet on the outer drum of the condensing washing and drying machine. Among them, the shell is formed on the rear drum of the outer drum, the air duct constitutes the rear air duct of the drying system, the air outlet of the condensing air duct assembly is connected to the outer drum, and the air inlet 12 of the condensing air duct assembly is connected to the outer drum. In this way, the dried gas can directly enter the air duct 11 from the air inlet 12 for dehumidification. At the same time, the dehumidified gas can also be directly returned to the inner drum for recycling through the air outlet 13, which is more convenient for the layout and use of the condensation duct assembly. It should be noted that the above-mentioned mutual communication between the two refers to the ability of gas or liquid to flow between the two, and does not indicate or limit the connection relationship between the two.

[0047] In summary:

[0048] 1. The condensing air duct assembly provided by the present invention is provided with a breaking-up structure 2. When airflow enters the air duct 11 through the air inlet 12 and cooling water flows in the air duct 11, the cooling water is broken up by the breaking-up structure 2, increasing the contact area between the cooling water and the airflow in the air duct 11. This indirectly increases the contact area between the water vapor in the airflow and the cooling water, making it easier for the water vapor in the airflow to be condensed by the cooling water. The cooling water can also condense more water vapor in the airflow, thereby reducing the consumption of condensed water and further conserving water resources.

[0049] 2. A guide groove 5 for avoiding the breaking up structure 2 can also be opened on the inner wall of the shell 1. When the flow rate of the cooling water is small and it is broken up, the cooling water can pass through the guide groove 5 instead of the breaking up structure 2, thereby preventing the cooling water from being carried out of the shell 1 by the airflow when the flow rate is small.

[0050] The above is only a preferred embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
