Therefore, this application is not intended to be limited to the embodiments shown, but rather to be in line with the broadest scope consistent with the principles and features disclosed in this application.

[0030] On the one hand, as Figures 1 to 8 shown, an embodiment of this application provides a lint collection device 1 including a connecting air duct 2 and a filter screen assembly 3. The connecting air duct 2 has a first end 21a and a second end 22a which are oppositely arranged. The connecting air duct 2 is provided on the front side of the inner tub 5 of the washing machine and is located between the drying air duct 4 and the door seal 51 of the washing machine. The first end 21a penetrates through the side wall of the door seal 51 and then communicates with the inner tub 5. The second end 22a extends along the outer surface of the inner tub 5 to communicate with the drying air duct 4. The filter screen assembly 3 is installed at the first end 21a, and the filter screen assembly 3 is used to filter the air entering the connecting air duct 2 from the inner tub 5.

[0031] In recent years, with the acceleration of the pace of life, in order to save the time for drying clothes, washing machines with a drying function are purchased and used by more and more people. Such washing machines have a drying air duct 4, which sucks air from the front side of the inner tub 5, heats it, and then blows it onto the clothes in the inner tub 5 to achieve the purpose of drying; during the long-term use of the washing machine, lint will flow in the drying channel along with the air, and the air will carry the lint onto the clothes to be dried, which may cause allergies in users with sensitive skin; the lint will also accumulate and remain in the inner tub 5, producing an unpleasant smell in a humid and hot environment, and even generating mold; the lint may also block the air duct, affecting the drying efficiency of the washing machine and causing energy waste. Currently, common washing machines with a drying function on the market also have a lint filter, but due to design reasons, the lint filter needs to be set at the top of the inner tub 5, which will make the height of the whole machine higher than that of a conventional washing machine, making it difficult to place the whole machine in a conventional washing machine cabinet and affecting the placement.

[0032] The lint collection device 1 provided in the embodiment of the present application is used to be installed on the side of the inner tub 5 of the washing machine. The drying air duct 4 and the inner tub 5 are communicated through the lint collection device 1. Among them, the lint collection device 1 includes a connecting air duct 2 for passing air and a filter screen assembly 3 for collecting lint. The inner tub 5 has a door seal 51. The first end 21a of the connecting air duct 2 passes through the side wall of the door seal 51, so that the connecting air duct 2 is communicated with the inner tub 5. The filter screen assembly 3 is arranged at the first end 21a. When the connecting air duct 2 intakes air from the inner tub 5, the lint in the air can be collected or filtered by the filter screen assembly 3, so that the air entering the drying air duct 4 from the connecting air duct 2 remains clean. With such a setting, since the connecting air duct 2 extends on the front side of the inner tub 5 and does not extend to a position exceeding the top of the inner tub 5, the height of the whole machine can be reduced, ensuring that the height of the washing machine with the lint collection device 1 will not be higher than that of a conventional washing machine.

[0033] In some embodiments, the connecting air duct 2 includes a first connecting section 21 and a second connecting section 22 that are connected in communication. The first connecting section 21 and the second connecting section 22 are detachably connected. The first end 21a is located at the lower end of the first connecting section 21, and the second end 22a is located at the upper end of the second connecting section 22. At least part of the drying air duct 4 is arranged on the top of the inner tub 5. The door seal 51 is arranged on the front side of the inner tub 5. The first connecting section 21 penetrates the top wall of the door seal 51 along the front side surface of the inner tub 5, so that the first end 21a faces the inside of the inner tub 5. The second connecting section 22 extends upward to the top of the inner tub 5, so that the second end 22a is connected to the drying air duct 4.

[0034] Specifically, the first connecting section 21 and the second connecting section 22 are detachably connected. The drying air duct 4 includes a connecting pipe 41, an upper air duct 42, a left air duct 43, an air duct connecting section 44, and a right air duct 45 that are connected in sequence. The connecting pipe 41 is used to communicate the upper air duct 42 and the connecting air duct 2. The right air duct 45 is used to blow air into the inner tub 5. The connecting pipe 41 is a corrugated hose. Part of the connecting pipe 41 is located on the top of the inner tub 5, and the other part hangs down to the front side surface of the inner tub 5. The second connecting section 22 extends upward along the inner tub 5 into the connecting pipe 41. The first connecting section 21 extends downward along the front side surface of the inner tub 5 and penetrates into the inside of the door seal 51, so that the first end 21a faces the inner tub 5. With such a setting, it is convenient to clean and maintain the filter screen assembly 3. After drying is completed, the first connecting section 21 can be removed to clean the filter screen assembly 3, ensuring the filtering performance of the filter screen assembly 3. In some other embodiments, the first connecting section 21 and the second connecting section 22 are integrally injection-molded.

[0035] Further, the air first passes through the filter screen 32 assembly for filtration, enters the connecting pipe 41 through the connecting air duct 2 and then enters the upper air duct 42. The washing machine is provided with a fan assembly, which provides power for the high-temperature and high-humidity air to enter the left air duct 43, enters the evaporator for dehumidification through the air duct connecting section 44, is heated by the condenser and then enters the right air duct 45 through the air duct connecting section 44, and finally the high-temperature and dry gas is introduced into the inner tub 5 for drying.

[0036] In some embodiments, the connecting air duct 2 includes a pressing buckle 23 and a clamping convex part 24. The pressing buckle 23 is arranged on the first connecting section 21, the clamping convex part 24 protrudes from the outer surface of the first connecting section 21, and the inner surface of the second connecting section 22 is provided with a clamping hole 22b and a plugging hole 22c. The clamping hole 22b and the plugging hole 22c are arranged oppositely. The clamping convex part 24 is used for clamping the plugging hole 22c, and the pressing buckle 23 is detachably plugged into the clamping hole 22b.

[0037] Specifically, the outer surface of the first connecting section 21 has a notch, the pressing buckle 23 protrudes into the notch, the pressing buckle can move within the notch, and in the natural state, the pressing buckle 23 protrudes towards the outside of the first connecting section 21. The clamping convex part 24 is located on the opposite side of the pressing buckle 23. In this embodiment, there are two clamping convex parts 24, and the two clamping convex parts 24 are arranged at intervals. The inner surface of the second connecting section 22 is provided with a clamping hole 22b and two plugging holes 22c. The clamping convex parts 24 are first plugged into the plugging holes 22c one by one, and then the pressing buckle 23 is pressed towards the inside of the first connecting section 21 to clamp the pressing buckle 23 in the clamping hole 22b, so as to realize the connection between the first connecting section 21 and the second connecting section 22. Pressing the pressing buckle 23 inward again can make the pressing buckle 23 disengage from the clamping hole 22b, and at this time, the first connecting section 21 and the second connecting section 22 can be disassembled. With this setting, the structure of the pressing buckle 23 is simple and the operation is convenient, making the disassembly and assembly of the first connecting section 21 and the second connecting section 22 convenient, and the clamping convex part 24 can increase the connection stability between the two. In some other embodiments, a plurality of first magnetic attraction parts are arranged on one side of the first connecting section 21 facing the second connecting section 22, and a plurality of second magnetic attraction parts are arranged on the edge of the opening of the second connecting section 22, and the first magnetic attraction parts and the second magnetic attraction parts are adsorbed to each other one by one.

[0038] In some embodiments, the second connecting section 22 is sleeved and connected to the first connecting section 21, and a limiting stop strip 21b protrudes from the outer surface of the first connecting section 21. The limiting stop strip 21b is used for abutting against the lower edge of the second connecting section 22 to limit the movement of the second connecting section 22 towards the first connecting section 21.

[0039] Specifically, the second connecting section 22 is sleeved outside the first connecting section 21, and the two are snap-connected together through a pressing buckle 23 and a clamping convex portion 24. Four limiting bars 21b are convexly provided on the outer surface of the first connecting section 21, two limiting bars 21b are provided on the side where the pressing buckle 23 is provided, and two limiting bars 21b are provided on the side where the clamping convex portion 24 is provided. The limiting bars 21b extend in a long strip shape along the left-right direction of the first connecting section 21. The limiting bars 21b can prevent the second connecting section 22 from moving excessively towards the first connecting section 21. With such a setting, when the second connecting section 22 and the first connecting section 21 are connected, the pressing buckle 23 will not be blocked due to excessive movement of the second connecting section 22. In some other embodiments, a limiting groove 31a is provided on the outer surface of the first connecting section 21, and an abutting convex portion is provided on the inner surface of the second connecting section 22. When the second connecting section 22 is sleeved on the first connecting section 21, the abutting convex portion can fall into the limiting groove 31a, and the bottom wall of the limiting groove 31a is used to abut against the abutting convex portion.

[0040] In some embodiments, an arc-shaped air duct 21c is provided inside the first connecting section 21. The inlet of the arc-shaped air duct 21c faces the inner barrel 5, and the outlet of the arc-shaped air duct 21c faces the second connecting section 22 and communicates with the second connecting section 22.

[0041] Specifically, an arc-shaped air duct 21c is provided inside the first connecting section 21, so that the first connecting section 21 has an arc-shaped structure. There is an included angle between the inlet direction and the outlet direction of the arc-shaped air duct 21c. The inlet of the arc-shaped air duct 21c faces the inner barrel 5, and the outlet of the arc-shaped air duct 21c faces the second connecting section 22 above. With such a setting, the first end 21a can be as close as possible to the inside of the inner barrel 5, so that the first end 21a has the ability to guide air, can quickly guide the air in the inner barrel 5 to the inlet of the arc-shaped air duct 21c, and quickly introduce the air into the second connecting section 22. In some other embodiments, the first connecting section 21 has a straight cylinder structure, and the inlet of the straight cylinder structure faces the lower side surface of the door seal 51 after extending into the door seal 51.

[0042] In some embodiments, the filter assembly 3 is hermetically installed at the inlet of the arc-shaped air duct 21c, and the outer peripheral edge of the filter assembly 3 abuts against the inner surface of the arc-shaped air duct 21c.

[0043] Specifically, the filter assembly 3 is arranged at this position to be able to contact the air in the inner barrel 5 as soon as possible, so as to filter out the lint in the air outside the filter assembly 3. The outer peripheral edge of the filter assembly 3 can seal the inlet of the arc-shaped air duct 21c. With such a setting, there is no gap between the filter assembly 3 and the inner surface of the first connecting section 21, and air will not flow into the first connecting section 21 from the gap, ensuring that the air entering the connecting air duct 2 has no lint.

[0044] In some embodiments, the filter assembly 3 includes a bracket 31 and a filter screen 32. The filter screen 32 is fixed within the bracket 31. The bracket 31 is provided with a groove 31a, and an installation protrusion 21d protrudes from the inner surface of the arc-shaped air duct 21c. The installation protrusion 21d is inserted into the groove 31a, and the installation protrusion 21d can press the bracket 31 against the inner surface of the arc-shaped air duct 21c.

[0045] Specifically, the bracket 31 is a rectangular frame structure, and the filter screen 32 is fixed at the vacant position in the middle of the bracket 31. Two grooves 31a are provided on the upper edge of the bracket 31. Correspondingly, two installation protrusions 21d protrude from the inner surface of the arc-shaped air duct 21c. The bracket 31 is placed obliquely in the arc-shaped air duct 21c. At this time, the installation protrusion 21d is inserted into the groove 31a, and the installation protrusion 21d can press the groove 31a, thereby pressing the entire bracket 31 against the inner surface of the arc-shaped air duct 21c. Such a setting is to achieve a sealed connection between the bracket 31 and the inlet of the arc-shaped air duct 21c. The mesh number of the filter screen 32 is from 100 mesh to 200 mesh. In this embodiment, the mesh number of the filter screen 32 is 120 mesh.

[0046] In some embodiments, the outer peripheral edge of the bracket 31 is made of an elastic material.

[0047] Specifically, the outer peripheral edge of the bracket 31 is made of elastic silicone material. When the bracket 31 is installed in the arc-shaped air duct 21c, the outer peripheral edge of the bracket 31 can undergo a certain deformation, that is, the bracket 31 is in interference fit connection with the inlet of the arc-shaped air duct 21c. Such a setting can increase the friction between the bracket 31 and the inner surface of the arc-shaped air duct 21c, thereby increasing the installation stability of the bracket 31 and making it not easy to disengage from the first connection section 21. In some other embodiments, anti-slip particles are provided on the inner surface of the arc-shaped air duct 21c, and the outer peripheral edge of the bracket 31 is used to contact the anti-slip particles.

[0048] In some embodiments, the second connection section 22 is in interference fit connection with the drying air duct 4, and a limiting ring protrusion is provided on the outer surface of the second connection section 22. The limiting ring protrusion is used to abut against the outer peripheral edge of the inlet of the drying air duct 4.

[0049] Specifically, the second connection section 22 is in interference fit connection with the connecting pipe 41 in the drying air duct 4, so that the connection stability between the second connection section 22 and the connecting pipe 41 is relatively high. A limiting ring protrusion is provided on the outer surface of the second connection section 22. The limiting ring protrusion extends circumferentially along the second connection section 22 in a ring shape, and the upper surface of the limiting ring protrusion is used to abut against the edge of the pipe orifice of the connecting pipe 41. Such a setting can determine whether the second connection section 22 is installed properly by whether the limiting ring protrusion abuts against the edge of the pipe orifice of the connecting pipe 41 when the second connection section 22 is installed and connected to the drying air duct 4. When the limiting ring protrusion abuts against the connecting pipe 41, it is considered installed properly.

[0050] On the other hand, an embodiment of the present application provides a washing machine, which includes the lint collection device 1, the inner tub 5 and the drying air duct 4 as described above, and the inner tub 5 is communicated with the drying air duct 4 through the lint collection device 1.

[0051] The lint collection device and the washing machine provided by the embodiments of the present application have been introduced in detail above. Specific examples are used in this article to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the method and its core idea of the present application; at the same time, for those skilled in the art, according to the idea of the present application, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present application.
