[0031] In order to solve the problem that it is difficult to clean the filter part of the condensing device in the prior art, the present application provides a condensing device and a washer-dryer having the same.

[0032] Example 1

[0033] like Figure 3 As shown, the condensing device includes a condensing structure 10 and a filtering structure 20. The condensing structure 10 has a condensing chamber 11, a liquid inlet 12, an air inlet and an exhaust port 13. The condensing chamber 11 is connected to the liquid inlet 12, the air inlet and the exhaust port 13, and the air inlet is located below the exhaust port 13. The filtering structure 20 is arranged in the condensing structure 10, and the filtering structure 20 is located between the air inlet and the exhaust port 13, so that the hot and humid gas enters the condensing chamber 11 through the air inlet, and the impurities in the hot and humid gas are filtered through the filtering structure 20. The heat exchange medium enters the condensing chamber 11 through the liquid inlet 12 to exchange heat with the hot and humid gas in the condensing chamber 11. The heat exchange medium flows to the filtering structure 20 under the action of its own weight to clean the filtering structure 20.

[0034] By applying the technical solution of this embodiment, during the operation of the condensing device, after the hot and humid gas enters the condensing chamber 11 through the air inlet, the hot and humid gas exchanges heat with the heat exchange medium located in the condensing structure 10, so that the water vapor in the hot and humid gas is liquefied into condensate. The gas after the heat exchange is discharged from the condensing device through the exhaust port 13 for recycling. Among them, after the hot and humid gas enters the condensing structure 10, the filter structure 20 can filter impurities such as hair and lint mixed in the hot and humid gas, and the heat exchange medium flows toward the filter structure under the action of its own weight to clean the filter structure, thereby solving the problem of the difficulty in cleaning the filter part of the condensing device in the prior art, so as to keep the filter structure clean and improve the filtering effect of the filter structure.

[0035] In other embodiments not shown in the accompanying drawings, the condensate formed after the heat exchange medium and the hot and humid gas condense flows to the filter structure under the action of its own weight to clean the filter structure. Specifically, during the operation of the condensing device, after the hot and humid gas enters the condensing chamber through the air inlet, the hot and humid gas exchanges heat with the heat exchange medium located in the condensing structure, so that the water vapor in the hot and humid gas is liquefied into condensate, and the gas after the heat exchange is discharged to the outside of the condensing device through the exhaust port for recycling. Among them, after the hot and humid gas enters the condensing structure, the filter structure can filter impurities such as dander and lint mixed in the hot and humid gas, and the heat exchange medium and condensate flow to the filter structure under the action of their own weight to clean the filter structure, thereby solving the problem that the filter part of the condensing device in the prior art is difficult to clean, so that the filter structure is kept clean, thereby improving the filtering effect of the filter structure.

[0036] In this embodiment, the heat exchange medium is condensed water. During the process of flushing the filter structure 20 with condensed water, the heat exchange efficiency between the filter structure 20 and the moist hot air is also increased, thereby improving the drying performance and user comfort.

[0037] Optionally, the filter structure 20 includes a plurality of filter elements, which are spaced apart along the height direction of the condensing device. Figure 3 As shown, the filter structure 20 includes three filter elements, which are spaced apart along the height direction of the condensing device. The three filter elements filter impurities in the hot and humid gas in turn to ensure that clean gas is discharged from the exhaust port 13, thereby improving the filtering efficiency of the filter structure 20.

[0038] Specifically, the air inlet is located below the exhaust port 13 and at the lower end of the filter structure 20. The hot and humid gas enters the condensation chamber 11 from bottom to top through the air inlet and passes through the three filter elements in sequence. The three filter elements filter impurities in the hot and humid gas to ensure that clean gas enters the exhaust port 13.

[0039] It should be noted that the number of filter elements is not limited thereto. Optionally, the filter structure 20 includes two, four, or five filter elements.

[0040] like Figure 3 As shown, the condensation structure 10 includes a first body 14 and a second body 15 connected to the first body 14. The first body 14 and the second body 15 are connected to form a condensation chamber 11. The first body 14 and the second body 15 are respectively located on either side of the filter element. In this way, the first body 14 and the second body 15 are processed separately, and the three filter elements are connected to the first body 14 or the second body 15 respectively. Thereafter, the first body 14 and the second body 15 are connected to form the condensation structure 10, thereby making the processing of the condensation device easier and simpler, reducing the processing difficulty and processing cost.

[0041] like Figure 3 and Figure 4 As shown, the three filter elements include a first filter element 21 and a second filter element 22. The first filter element 21 has a first filter hole 210. The second filter element 22 is located below the first filter element 21 and has a second filter hole larger than the first filter hole 210. This allows the second filter element 22 to perform a coarse filter on the hot and humid gas, while the first filter element 21 then performs a fine filter on the hot and humid gas, thereby enhancing the filtering effect of the filter structure 20.

[0042] Specifically, the hot and humid gas entering the air inlet is first filtered by the second filter element 22 and then filtered by the first filter element 21. The first filter element 21 and the second filter element 22 filter the hot and humid gas respectively, thereby improving the filtering efficiency and filtering effect of the filter structure 20, ensuring that clean gas enters the exhaust port 13.

[0043] like Figure 3 As shown, the first filter element 21 is plate-shaped and is tilted relative to the first body 14 and the second body 15. The first filter element 21 has a first end for connecting to the first body 14 and a second end for connecting to the second body 15. The first end is located below the second end. The first body 14 has a first plate segment for connecting to the first end. The plate surface of the first filter element 21 facing the exhaust port 13 is arranged at a first angle A1 with the first plate segment. Thus, the tilted arrangement of the first filter element 21 within the condensation chamber 11 reduces the impact of the heat exchange medium on the first filter element 21. It also ensures that the heat exchange medium can flow smoothly through the first filter element 21 to the second filter element 22, improving the flow of the heat exchange medium and ensuring that the heat exchange medium can flow through the first filter element 21 to the second filter element 22, thereby cleaning the first and second filters 21 and 22.

[0044] like Figure 3 As shown, the second end portion is located below the liquid inlet 12, and a first height difference H1 is defined between the end surface of the second end portion facing the liquid inlet 12 and the liquid inlet 12. Specifically, the flow direction of the hot and humid gas is opposite to that of the heat exchange medium. To ensure that the heat exchange medium can clean both the first filter element 21 and the second filter element 22, the end surface of the second end portion facing the liquid inlet 12 does not exceed the lowest water level of the liquid inlet 12.

[0045] It should be noted that the positional relationship between the end surface of the second end facing the liquid inlet 12 and the liquid inlet 12 is not limited to this. Optionally, the end surface of the second end facing the liquid inlet 12 is flush with the liquid inlet 12.

[0046] like Figure 3As shown, the second filter element 22 is plate-shaped and is tilted relative to the first body 14 and the second body 15. The second filter element 22 has a third end for connecting to the first body 14 and a fourth end for connecting to the second body 15. The third end is located above the fourth end. The second body 15 has a second plate segment for connecting to the fourth end. The plate surface of the second filter element 22 facing the exhaust port 13 is arranged at a second angle A2 with the second plate segment. Thus, the tilted arrangement of the second filter element 22 within the condensing chamber 11 reduces the impact of the heat exchange medium on the second filter element 22. Furthermore, it ensures that the heat exchange medium can flow smoothly through the second filter element 22 to the lower outlet of the condensing structure 10, improving the flow of the heat exchange medium and ensuring that the heat exchange medium can flow through the first filter element 21 and the second filter element 22 to clean the first filter element 21 and the second filter element 22.

[0047] like Figure 3 As shown, the third end portion is located below the first end portion, and a second height difference H2 is defined between the end surface of the third end portion facing the first end portion and the end surface of the first end portion facing the third end portion. Specifically, the flow direction of the hot and humid gas is opposite to that of the heat exchange medium. To prevent backflow of the hot and humid gas within the condensation chamber 11, the end surface of the third end portion facing the first end portion needs to be no higher than the end surface of the first end portion facing the third end portion.

[0048] It should be noted that the positional relationship between the end surface of the third end facing the first end and the end surface of the first end facing the third end is not limited to this. Optionally, the end surface of the third end facing the first end is flush with the end surface of the first end facing the third end.

[0049] like Figure 3 As shown, the three filter elements also include a third filter element 23. The third filter element 23 is located below the second filter element 22 and has a third filter hole whose diameter is larger than that of the second filter hole. Specifically, the first, second, and third filter holes are all circular, and the diameters D1, D2, and D3 of the first, second, and third filter holes satisfy the following relationship: D1 ≤ D2 ≤ D3. The third filter element 23 performs coarse filtration of impurities in the hot and humid air, removing large particles. The second filter element 22 performs fine filtration of impurities in the hot and humid air, removing remaining large particles. The hot and humid air then passes through the first filter element 21, which performs fine filtration of small particles. The heat exchange medium flushes and cleans impurities remaining on the first, second, and third filter elements 21, 22, and 23.

[0050] like Figure 3As shown, the third filter element 23 is plate-shaped and is tilted relative to the first body 14 and the second body 15. The third filter element 23 has a fifth end for connecting to the first body 14 and a sixth end for connecting to the second body 15. The fifth end is located below the sixth end. The first body 14 also has a third plate segment for connecting to the fifth end. The plate surface of the third filter element 23 facing the exhaust port 13 is arranged at a third angle A3 with the third plate segment. Thus, the tilted arrangement of the third filter element 23 within the condensing chamber 11 reduces the impact of the heat exchange medium on the third filter element 23 and ensures that the heat exchange medium can flow smoothly through the third filter element 23 to the lower outlet of the condensing structure 10, thereby improving the flow of the heat exchange medium and ensuring that the heat exchange medium can flow through the first filter element 21, the second filter element 22, and the third filter element 23 to clean the first filter element 21, the second filter element 22, and the third filter element 23.

[0051] like Figure 3 As shown, the sixth end portion is located below the fourth end portion, and a third height difference H3 is defined between an end surface of the sixth end portion facing the fourth end portion and an end surface of the fourth end portion facing the sixth end portion. Specifically, the flow direction of the hot and humid gas is opposite to that of the heat exchange medium. To prevent backflow of the hot and humid gas within the condensation chamber 11, the end surface of the sixth end portion facing the fourth end portion needs to be no higher than the end surface of the sixth end portion facing the fourth end portion.

[0052] It should be noted that the positional relationship between the end surface of the sixth end facing the fourth end and the end surface of the fourth end facing the sixth end is not limited to this. Optionally, the end surface of the sixth end facing the fourth end is flush with the end surface of the fourth end facing the sixth end.

[0053] In this embodiment, the first height difference H1, the second height difference H2, and the third height difference H3 satisfy the following relationship: H3 ≥ H2 ≥ H1 ≥ 0. Thus, the above arrangement ensures that the heat exchange medium can flow smoothly within the condensing chamber 11 and also improves the heat exchange efficiency between the hot and humid air and the heat exchange medium.

[0054] Optionally, the first angle A1, the second angle A2, and the third angle A3 satisfy the following relationship: 90° ≥ A1 ≥ A2 ≥ A3 ≥ 10°. Thus, the above-described arrangement of the first angle A1, the second angle A2, and the third angle A3 can ensure that the heat exchange medium can flow smoothly within the condensing chamber 11, thereby improving the heat exchange efficiency between the hot and humid air and the heat exchange medium.

[0055] like Figure 1 and Figure 2As shown, the present application also provides a washing and drying machine, including a cylinder 30, a fan 40, a heating device 50 and a condensing device, the air outlet of the cylinder 30 is connected to the air inlet of the condensing device, and the exhaust port 13 of the condensing device is connected to the heating device 50. Among them, the condensing device is the above-mentioned condensing device. Specifically, during the operation of the washing and drying machine, the fan 40 draws the air flow to the position of the heating device 50, the heating device 50 heats the gas, and the heated gas enters the cylinder 30 to dry the clothes, then the high-temperature gas is converted into a sub-high-temperature and high-humidity gas (humid and hot gas), the sub-high-temperature and high-humidity gas (humid and hot gas) enters the condensing structure 10 through the air inlet, the heat exchange medium enters the condensing chamber 11 through the liquid inlet 12 and exchanges heat with the sub-high-temperature and high-humidity gas (humid and hot gas), so that the water vapor in the sub-high-temperature and high-humidity gas (humid and hot gas) is liquefied, and the dry gas enters the heating device 50 through the exhaust port 13 to dry the clothes again until the clothes are fully dried.

[0056] Example 2

[0057] The condensing device in the second embodiment differs from that in the first embodiment in that the connection method between the filtering structure and the condensing structure is different.

[0058] like Figure 5 As shown, the third filter hole has a diameter of D3. A first gap W1 is defined between the end of the first filter element 21 near the first body 14 and the first body 14. A second gap W1 is defined between the end of the second filter element 22 near the second body 15 and the second body 15. A third gap W2 is defined between the end of the third filter element 23 near the first body 14 and the first body 14, wherein: 0 < W1 < W2 < W3 < D3. Specifically, the above-described arrangement of the first gap W1, the second gap W2, and the third gap W3 forms a water flow channel between the first filter element 21, the second filter element 22, and the third filter element 23 and the condensation structure 10, thereby ensuring that the heat exchange medium can flow smoothly within the condensation structure 10.

[0059] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0060] During operation of the condensing device, when the hot and humid gas enters the condensing chamber through the air inlet, it exchanges heat with the heat exchange medium located within the condensing structure, liquefying the water vapor in the hot and humid gas into condensate. The gas, after completing the heat exchange, is discharged from the condensing device through the exhaust port for recycling. After the hot and humid gas enters the condensing structure, the filter structure filters impurities such as lint and lint contained in the hot and humid gas. The heat exchange medium and / or condensate flow toward the filter structure under its own weight to clean the filter structure, thereby resolving the difficulty in cleaning the filter portion of the condensing device in the prior art. This allows the filter structure to remain clean, thereby improving the filtering effect of the filter structure.
