Description

Technical Field

[0001] The present application relates to the field of electrical appliance technology, and in particular to a filtering mechanism and a washing machine. Background Art

[0002] With the rapid development of science and technology and the demand for more versatile washing machine functions, a multifunctional washing machine that integrates washing and drying functions has come into the public eye. Since this type of washing machine adds a drying function on top of the cleaning function of traditional washing machines, it greatly improves the convenience of handling clothes, and is therefore loved by more and more people.

[0003] In the related art, in order to realize the drying function of the washing machine, a drying component connected to the outer drum of the washing machine is usually provided in the machine body. Generally, the air inlet of the drying component is provided with a filter for filtering impurities such as lint between the inner drum and the outer drum of the washing machine, and is also provided with a mechanism for spraying impurities on the filter to make the impurities fall off. However, the water flow will not only be thrown onto the filter with the rotation of the inner drum, but also accumulate on the filter during spraying, thereby forming a water film. When the user uses the drying function, the airflow will be blocked by the water film and cannot enter the drying component. At this time, the drying channel is prone to dry burning, which will cause damage to the drying component and affect the normal use of the drying component or the washing machine.

DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0042] Unless otherwise defined, all technical terms used in the embodiments of the present application have the same meanings as commonly understood by those skilled in the art.

[0043] In order to make the technical solutions and advantages of the present application more clear, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0044] Combination Figure 1 and Figure 2 As shown, the embodiment of the present application provides a filtering mechanism, which includes a tube body 100, a filter screen 200 and a vent 500. The air inlet end of the tube body 100 is suitable for communicating with the outer drum 300 of the washing machine, and the air outlet end of the tube body 100 is suitable for communicating with the air inlet end of the drying assembly 400.

[0045] It should be noted that the washing machine in the embodiment of the present application can be a drum washing machine. The drying assembly 400 generally includes a drying channel, a heating device and a fan. The gas enters the tube body 100 after passing through the filter 200 between the inner drum 700 and the outer drum 300 of the washing machine, and then enters the drying assembly 400. The gas heated by the heating device flows from the air outlet of the drying assembly 400 to the inner drum 700 of the washing machine to dry the clothes in the inner drum 700. After the hot and humid gas condenses in the condensation part between the inner drum 700 and the outer drum 300 of the washing machine, it flows back to the drying assembly 400 according to the above path and is heated again, thereby realizing the circulation of the gas. The filter 200 can prevent impurities such as lint generated by the clothes during the drying process from entering the drying assembly 400.

[0046] The filter screen 200 is installed in the tube body 100. The vent 500 is coplanar with the filter screen 200, wherein the vent 500 allows the gas in the outer cylinder 300 to pass through and flow into the tube body 100. It is understandable that during the rotation of the inner cylinder 700, some water will be thrown onto the filter screen 200 to form a water film, which will block the flow of gas. However, since the filter mechanism in the embodiment of the present application is provided with the vent 500, and the gas can pass through the vent 500, it is possible to avoid the gas being blocked by the water film on the filter screen and unable to enter the tube body 100. That is, it is ensured that the gas can enter the drying component 400, so that the gas can circulate normally in the drying component 400, so that the drying component 400 will not have the phenomenon of dry burning. In other words, the filter mechanism provided in the embodiment of the present application can ensure that the drying component 400 is in normal working condition.

[0047] The following is combined with Figures 1 to 6 The details and functions of the filtering mechanism provided in the embodiments of the present application are described in more detail.

[0048] In some embodiments, the filter 200 has filter holes (not shown in the figure), and the size of the vent 500 is larger than the size of the filter holes. This ensures that the gas can always flow through the vent 500, and avoids the drying component 400 from being in a ventilated state. It should be noted that the size of the vent 500 can ensure that no water film is formed at the vent 500, that is, the vent 500 is always in an open state, ensuring that the gas can flow through the vent 500.

[0049] Combination Figures 1 to 3As shown, in some embodiments, the outer cylinder 300 is provided with a mounting hole 310, and the mounting hole 310 is located on a side of the outer cylinder 300 close to the drying assembly 400. The port at the air inlet end of the tube body 100 is connected to the mounting hole 310, and the filter screen 200 is arranged inside the port at the air inlet end of the tube body 100, wherein the filter screen 200 is inclined relative to the direction of gravity. In this arrangement, the water on the filter screen 200 is more easily affected by gravity and flows downward along the surface of the filter screen 200 and falls, avoiding excessive accumulation on the filter screen 200 to form a water film.

[0050] Combination Figure 1 and Figure 2 As shown, in some embodiments, the vent 500 is disposed on the filter 200. Alternatively, the vent 500 is formed between the filter 200 and the inner wall of the tube body 100. This ensures that when the gas flows through the surface where the filter 200 is located, it can not only enter the tube body 100 through the filter 200, but also enter the tube body 100 through the vent 500. This ensures that when a water film is formed on the filter 200, the gas can still flow into the drying component 400 through the vent 500, thereby preventing the drying component 400 from being damaged due to dry burning.

[0051] Combination Figure 2 and Figure 3 As shown, in some embodiments, the filter screen 200 is provided with a vent 500 at the lower part and near the edge in the gravity direction. With such a configuration, the water flowing along the surface of the filter screen 200 can also flow out directly from the vent 500, which helps to discharge the water on the filter screen 200. It should be noted that the filter screen 200 is connected to the inner wall of the tube body 100 in the circumferential direction.

[0052] Combination Figure 4 and Figure 5 As shown, in some embodiments, a portion of the filter screen 200 is connected to the inner wall of the tube body 100 in a circumferential direction. Another portion of the filter screen 200 is spaced from the inner wall of the tube body 100 in a circumferential direction to form a vent 500. For example, the filter screen 200 may include connected arc sides and straight sides, wherein the arc sides are connected to the inner wall of the tube body 100, and the straight sides are spaced from the inner wall of the tube body 100 to form a vent 500.

[0053] Combination Figure 4 and Figure 5 As shown, in some embodiments, the side of the filter screen 200 located below the gravity direction is spaced from the inner wall of the tube body 100 to form a vent 500. For example, in the filter screen 200 surrounded by the arc side and the straight side, the straight side is the side located below the gravity direction, so that the vent 500 can also provide a sliding channel for the water flowing along the surface of the filter screen 200 to prevent the water from accumulating into a water film on the filter screen 200.

[0054] Combination Figures 2 to 5 As shown, in some embodiments, the filter mechanism further includes at least one reinforcing rib 600, the two ends of the reinforcing rib 600 are respectively connected to the inner wall of the tube body 100, and the portion between the two ends of the reinforcing rib 600 is connected to the filter screen 200. It should be noted that the reinforcing rib 600 can improve the strength of the filter screen 200 and prevent the filter screen 200 from being deformed. The reinforcing rib 600 and the filter screen 200 can be an integrally formed structure, or they can be fixed together by a fixing member.

[0055] Combination Figures 2 to 5 As shown, in some embodiments, the filter mechanism includes two reinforcing ribs 600, and the two reinforcing ribs 600 are arranged crosswise. Such an arrangement can further improve the strength of the filter screen 200. It should be noted that the two reinforcing ribs 600 can be perpendicular to each other, or they can form an angle of 30 degrees, 60 degrees, etc. In some embodiments, the vent 500 is located in the area below the gravity direction formed by the intersection of the two reinforcing ribs 600. This makes it easier for water flow or impurities to fall from the vent 500 due to gravity.

[0056] like Figure 6As shown, in some embodiments, the tube body 100 includes an inner tube 110 and an outer tube 120, and a receiving chamber 130 is formed between the inner tube 110 and the outer tube 120, and the receiving chamber 130 is used to receive liquid. The outer tube 120 is provided with a water inlet 121, and the inner tube 110 is provided with a water outlet 111, and the water outlet 111 faces the filter 200, and the water inlet 121, the receiving chamber 130 and the water outlet 111 are connected in sequence. It can be understood that the clothes washed in the washing machine will carry impurities such as lint, and during the drying process, the impurities such as lint will flow along with the airflow. Since the airflow will first pass through the filter 200 and then flow into the drying assembly 400, the filter 200 will filter most of the lint, and some lint will remain on the filter 200. By providing the connected water inlet 121, the accommodating cavity 130 and the water outlet 111, water can be sprayed out from the water outlet 111 to flush the impurities such as lint accumulated on the filter 200, so that the impurities can fall to the area between the inner drum 700 and the outer drum 300 of the washing machine under the force of gravity, and then flow to the sewage outlet, thereby cleaning the filter 200 and ensuring that the filter 200 maintains a good filtering effect. It should be noted that in the process of flushing the filter 200, some lint will be washed to the edge after being wetted. Since the above-mentioned vent 500 is located below the filter 200 in the direction of gravity and close to the edge, or the vent 500 is located on the side of the filter 200 in the direction of gravity, the lint is also more likely to fall from the vent 500 located below to the area between the inner drum 700 and the outer drum 300 of the washing machine under the force of gravity, and then flow to the sewage outlet and be discharged together with the dirt. That is to say, by providing the water outlet 111 for flushing impurities such as fluff and the vent 500 for providing a falling channel for the fluff, it is possible to prevent impurities such as fluff from accumulating on the filter 200, thereby improving the cleanliness of the filter 200. It should be noted that the water outlet 111 facing the filter 200 generally means that the liquid sprayed from the water outlet 111 can pass through the filter 200. For example, when the water outlet 111 is located above the filter 200, the liquid sprayed from the water outlet 111 generally passes through the filter 200, and then flows to the drain outlet through the cavity formed between the inner drum 700 and the outer drum 300 of the washing machine.

[0057] like Figure 6 As shown, in some embodiments, the inner tube 110 is provided with a plurality of water outlets 111, and the plurality of water outlets 111 are distributed at intervals along the circumference of the inner tube 110. With such a configuration, the filter screen 200 can be flushed more comprehensively, further improving the cleanliness of the filter screen 200.

[0058] Combination Figures 1 to 6As shown, an embodiment of the present application further provides a washing machine, which includes a filtering mechanism as described in any one of the above embodiments of the present application. It should be noted that the filtering mechanism in the washing machine provided in the embodiment of the present application has the same components and corresponding functions as the filtering mechanism provided in the above embodiments of the present application, so the embodiments of the present application will not be repeated here. The washing machine can be a drum type washing machine. Since the filtering mechanism can ensure that the drying component 400 will not dry burn and ensure that the drying component 400 can work normally, it not only improves the service life of the drying component 400, but also improves the service life of the washing machine.

The present application is intended to cover any variations, uses or adaptations of the present application, which follow the general principles of the present application and include common knowledge or customary techniques in the art that are not disclosed in the present application.
