[0043] Example 1

[0044] In one specific embodiment, the condensation device provided in this application includes a main body 1 and a spray assembly 2. The main body 1 has a first cavity 11 and a filter screen 12. The filter screen 12 is located inside the first cavity 11 and is used to filter impurities or other particulate matter generated during the condensation process. The circumferential edge of the filter screen 12 is closely fitted with the circumferential edge of the first cavity 11 to improve the filtration effect. The main body 1 is generally set to be circular or elliptical, and can be set as needed. The main body 1 is provided with a first cavity 11. Correspondingly, the first cavity 11 is set to be a circular cavity structure or an elliptical cavity structure, and can be set accordingly according to the shape of the main body 1.

[0045] The spray assembly 2 is located inside the first cavity 11 and above the filter screen 12. It sprays water onto the filter screen 12 from top to bottom. This is because lint and other impurities adhere to the lower wall of the filter screen 12. The spray assembly 2 washes the filter screen 12 from top to bottom, allowing the washed lint and other impurities to flow down with the water. Simultaneously, the spray assembly 2 is positioned closer to the surface of the filter screen 12, increasing the water flow and improving the rinsing effect. The spray section 21 has several spray holes, with at least two spray holes having different spray directions. This increases the spray range of the spray assembly 2, allowing the water flow to be sprayed onto the filter screen 12 at multiple angles and through multiple holes, thus increasing the spray range and improving the lint removal effect.

The spray part 21 is provided with a plurality of spray holes, and at least two spray holes have different spray directions to increase the spray range of the spray assembly 2, so that the sprayed water is sprayed on the filter screen 12 at multiple angles and multiple holes, thereby increasing the spray range and improving the lint washing effect.

[0049] Example 2

[0050] This embodiment further improves upon the condensation device of Embodiment 1.

[0051] In this embodiment, the spray assembly 2 further includes a connecting part 22, which is located on the outer wall of the spray part 21 and is used to connect to an external water source; the connecting part 22 communicates with the tubular hollow cavity of the spray part 21; the connecting part 22 is detachably fixedly connected to the main body part 1.

[0052] The inner wall of the main body 1 is provided with a mounting hole 13, which extends along the wall thickness direction of the main body, and the connecting part 22 is located inside the mounting hole 13.

[0053] Understandably, to achieve connection with an external water source, the sprinkler assembly 2 also includes a connecting part 22, which communicates with the sprinkler part 21 and is used to supply water to the sprinkler part 21. Specifically, the connecting part 22 is disposed on the outer wall of the sprinkler part 21 and passes through the main body 1.

The connecting part 22 is responsible for introducing the external water source into the sprinkler part 21, ensuring smooth water flow.

[0054] Accordingly, the inner wall of the main body 1 is provided with a mounting hole 13, which extends along the wall thickness direction of the main body 1 and is used to install the connecting part 22. The connecting part 22 is fitted into the mounting hole 13. The detachable structural design facilitates cleaning and maintenance, improving the maintainability of the equipment. Specifically, the connecting part 22 can be configured as a tubular structure, which is fitted into the mounting hole 13 and achieves a detachable fixed connection with the main body 1.

[0055] Example 3

[0056] This embodiment further improves the condensation device of Embodiment 2.

[0057] In this embodiment, to facilitate the installation of the connecting part 22 and the main body 1, first mounting seats 23 are provided on both axial sides of the connecting part 22. The first mounting seats 23 are preferably welded to the connecting part 22. Each first mounting seat 23 has a first fixing mounting hole 221, which is a through hole. A second mounting seat 14 is provided below the mounting hole 13 of the main body 1. The second mounting seat 14 abuts against the first mounting seat 23.

[0058] By providing first mounting seats 23 on both sides of the axial direction of the connecting part 22, the installation stability is improved and the force is balanced.

[0062] The connecting part 22 is fitted into the mounting through hole of the sealing plug 24, and the sealing plug 24 is fitted into the mounting hole 13 of the main body 1. The sealing plug 24 achieves a sealed connection between the connecting part 22 and the main body 1, preventing water leakage or seepage, ensuring the normal operation of the sprinkler system, and providing a precise installation position for the connecting part 22 to ensure its accurate position.

[0063] Example 5

[0064] This embodiment further improves upon the condensation device of any of the above embodiments.

[0065] The condensation device provided in this application includes a main body 1 and a spray assembly 2. The main body 1 has a first cavity 11 and a filter screen 12. The filter screen 12 is located inside the first cavity 11 and is used to filter impurities or other particulate matter generated during the condensation process. The circumferential edge of the filter screen 12 is closely fitted with the circumferential edge of the first cavity 11 to improve the filtration effect. The main body 1 is generally set to be circular or elliptical, and can be set as needed. The main body 1 is provided with a first cavity 11. Correspondingly, the first cavity 11 is set to be a circular cavity structure or an elliptical cavity structure, and can be set accordingly according to the shape of the main body 1.

[0066] The spray assembly 2 is located inside the first cavity 11 and above the filter screen 12. It sprays water onto the filter screen 12 from top to bottom. This is because lint and other impurities adhere to the lower wall of the filter screen 12. The spray assembly 2 washes the filter screen 12 from top to bottom, allowing the washed lint and other impurities to flow down with the water. Simultaneously, the spray assembly 2 is positioned closer to the surface of the filter screen 12, increasing the water flow and improving the rinsing effect. The spray section 21 has several spray holes, with at least two spray holes having different spray directions. This increases the spray range of the spray assembly 2, allowing the water flow to be sprayed onto the filter screen 12 at multiple angles and through multiple holes, thus increasing the spray range and improving the lint removal effect.

[0067] In this embodiment, in order to increase the spray range of the spray assembly 2, the spray holes are divided into three parts. The first part of the spray holes has an angle of 135-150° with the horizontal direction, the second part of the spray holes has an angle of 90-110° with the horizontal direction, and the third part of the spray holes has an angle of 30-55° with the horizontal direction. This can achieve a multi-directional and multi-layer spray effect, so that the spray water can cover the entire filter screen 12 more evenly, thereby improving the spray effect on the lint on the filter screen 12.

[0068] Specifically, the angle between the first part of the spray holes and the horizontal direction is preferably 135 degrees, the angle between the second part of the spray holes and the horizontal direction is 90 degrees, and the angle between the third part of the spray holes and the horizontal direction is 45 degrees, thereby forming a multi-layered and multi-directional spray, which further enables the spray water to cover the entire filter screen 12 more evenly, increases the spray range, and improves the spray effect.

[0069] Example 6

[0070] This embodiment further improves upon the condensation device of any of the above embodiments.

[0071] In this application, the spray section 21 is a tubular hollow cavity formed by a closed curve. The spray section 21 can be specifically configured as an annular tubular structure, and the annulus can be configured as a circular ring or an elliptical structure. In other embodiments, the spray section 21 can also be configured as a rectangular tubular structure, thereby further increasing the spray area and reducing the weight of the spray section 21. The structure of the closed curve increases the strength and stability of the spray section 21, and also helps to form a uniform spray effect.

[0072] Example 7

[0073] This embodiment further improves upon the condensation device of Embodiment Six.

[0074] In this embodiment, the spray section 21 is composed of an upper spray section 21 and a lower spray section 21 with radial cross sections welded together, which facilitates manufacturing and assembly, and also facilitates future local maintenance and replacement.

[0075] Example 8

[0076] In this embodiment, the spray section 21 is an elliptical spray section 21, and a plurality of spray holes are provided around the elliptical spray section 21. At least two spray holes have different spray directions to increase the spray range of the spray assembly 2, so that the sprayed water is sprayed on the filter screen 12 at multiple angles and multiple holes, thereby increasing the spray range and improving the lint rinsing effect.

[0077] In this embodiment, in order to increase the spray range of the spray assembly 2, the spray holes are divided into three parts. The first part of the spray holes has an angle of 135-150° with the horizontal direction, the second part of the spray holes has an angle of 90-110° with the horizontal direction, and the third part of the spray holes has an angle of 30-55° with the horizontal direction. This can achieve a multi-directional and multi-layer spray effect, so that the spray water can cover the entire filter screen 12 more evenly, thereby improving the spray effect on the lint on the filter screen 12.

[0078] Specifically, the angle between the first part of the spray holes and the horizontal direction is preferably 135 degrees, the angle between the second part of the spray holes and the horizontal direction is 90 degrees, and the angle between the third part of the spray holes and the horizontal direction is 45 degrees, thereby forming a multi-layered and multi-directional spray, which further enables the spray water to cover the entire filter screen 12 more evenly, increases the spray range, and improves the spray effect.

[0079] The elliptical spray section 21 is a tubular hollow cavity formed by a closed curve. The elliptical spray section 21 further increases the spray area and reduces the weight of the spray section 21. The closed curve structure increases the strength and stability of the spray section 21, and also helps to form a uniform spray effect.

[0080] The spray section 21 is composed of an upper spray section 21 and a lower spray section 21 with radial cross sections welded together, which facilitates manufacturing and assembly, and also makes it convenient for future local maintenance and replacement.

[0081] In other embodiments, the spray section 21 can also be configured as a rectangular spray section 21. The structure of the spray section 21 can be configured as needed, as long as the same technical effect can be achieved.

[0082] In one specific embodiment, the condensing device provided in this application includes a main body 1 and a spray assembly 2. First, the upper spray section 21 and the lower spray section 21 of the spray section 21 are welded together to form the spray section 21. Then, a sealing plug 24 is fitted onto the connecting section 22. The assembled component is inserted into the mounting hole 13 of the main body 1. Screws are installed in the first fixing mounting hole 221 and the second fixing mounting hole 141 of the first mounting base 23 and the second mounting base 14. The condensing device is then fixed together with the filter screen 12 using two screws to form an integral condenser assembly. The condensing device is then fitted with a sealing ring and installed between the outer barrel and the drying tunnel using large screws. This structure is easy to install and can form a wide-range water flow with multiple holes when water enters the condenser to wash away the lint on the filter screen 12.

[0083] The main body 1 and the filter screen 12 are designed as an integrated structure for easy installation. The filter screen 12 is designed as a flat structure with drainage holes at its base to prevent residual water from forming. Meanwhile, the spray section 21 is installed from top to bottom, so that the spray holes are closer to the surface of the filter screen 12. During spraying, the water flow pressure on the filter screen 12 is greater, improving the rinsing effect. The upper spray section 21 and the lower spray section 21 are welded together to form the spray section 21, which has a hollow structure in the middle to facilitate airflow and make the water flow smoother when water enters. The spray section 21 has multiple holes, and some of the spray holes are set as angled holes, so that the sprayed water is sprayed on the filter screen 12 at multiple angles and holes, increasing the spray range and greatly improving the lint rinsing effect.

[0084] Based on the condensation device provided in the above embodiments, this application also provides a drying device, including:

[0085] The fan, the heating device, and the condensing device of any of the above embodiments,

[0086] The fan is located between the condensing unit and the heating unit, with its two ends connected to the condensing unit and the heating unit respectively.

[0087] When the drying device is installed inside the drum washing machine, it is connected to the door seal of the drum and connected to the rear tub of the drum through the opening of the first cavity 11, thus realizing a complete airflow circulation.

[0088] During the drying process, the high-humidity air after washing enters the condenser from the back of the drum. After being condensed by the condensate, the resulting low-humidity air enters the fan. The fan rotates and generates airflow, which sends the low-humidity air to the heating device to bake and heat the air. The air is then returned to the clothes in the drum to dry them.

[0089] The condensation device provided in this application includes a main body 1 and a spray assembly 2. The main body 1 has a first cavity 11 and a filter screen 12. The filter screen 12 is located inside the first cavity 11 and is used to filter impurities or other particulate matter generated during the condensation process. The circumferential edge of the filter screen 12 is closely fitted with the circumferential edge of the first cavity 11 to improve the filtration effect. The main body 1 is generally set to be circular or elliptical, and can be set as needed. The main body 1 is provided with a first cavity 11. Correspondingly, the first cavity 11 is set to be a circular cavity structure or an elliptical cavity structure, and can be set accordingly according to the shape of the main body 1.

[0090] The spray assembly 2 is located inside the first cavity 11 and above the filter screen 12. It sprays water onto the filter screen 12 from top to bottom. This is because lint and other impurities adhere to the lower wall of the filter screen 12. The spray assembly 2 washes the filter screen 12 from top to bottom, allowing the washed lint and other impurities to flow down with the water. Simultaneously, the spray assembly 2 is positioned closer to the surface of the filter screen 12, increasing the water flow and improving the rinsing effect. The spray section 21 has several spray holes, with at least two spray holes having different spray directions. This increases the spray range of the spray assembly 2, allowing the water flow to be sprayed onto the filter screen 12 at multiple angles and through multiple holes, thus increasing the spray range and improving the lint removal effect.
