Description

Technical Field

[0001] This utility model relates to the field of lint filtration technology, specifically to a lint filtration mechanism for a fully automatic washing machine. Background Technology

[0002] Patent CN 206616376 U discloses a magic lint filter structure for a fully automatic washing machine, comprising a main body including an outer tub, an inner tub, and a pulsator above the inner tub. The bottom of the inner tub has a drainage grid around its perimeter, and the pulsator has through holes and reinforcing ribs on its back. This application uses a magic lint filter plate structure. Through the optimized design of the drainage grid around the bottom of the tub, the water flow from the pulsator during washing directs lint into the outer tub, effectively isolating the lint. During drainage, the lint is automatically discharged with the water flow.

[0003] In the aforementioned patent, the optimized design of the drainage grid around the bottom of the tub allows the impeller water flow to discharge lint into the outer tub, thus filtering the lint and increasing the inner tub volume. However, as the lint is discharged with the water flow, the water containing the lint usually flows into the sewer, which can cause sewer blockage. It is necessary to install a new filtration system outside the drain pipe to prevent the water containing lint from flowing directly into the sewer, which makes it inconvenient for users when using the washing machine. Utility Model Content

[0004] The purpose of this invention is to provide a fully automatic washing machine lint filtering mechanism to address the aforementioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fully automatic washing machine lint filtering mechanism, comprising: a washing machine shell, an inner drum, an outer drum, and a pulsator. The pulsator is disposed at the bottom of the inner drum, and inclined drainage holes are provided on the pulsator, with adjacent drainage holes having opposite inclination directions. Liquid passage holes are provided on the inner drum, and the liquid passage holes are located below the drainage holes and are interconnected. A water pipe is fixedly connected to the lower end of the outer drum, and a water pump and a filter assembly are provided on the water pipe. The other end of the water pipe is connected to an annular guide tube, and multiple nozzles are arrayed at the bottom of the annular guide tube.

[0006] Furthermore, the outer tub is fixedly connected to the outer shell of the washing machine, and the outer tub is sleeved outside the inner tub, with the bottom of the inner cavity of the outer tub being funnel-shaped.

[0007] Furthermore, a one-way valve is installed inside the water pipe, and the one-way valve is located between the outer cylinder outlet and the filter assembly.

[0008] Furthermore, the filter assembly includes a filter housing, which is fixedly connected to the washing machine housing. A filter box is slidably disposed inside the filter housing, and a first filter screen and a second filter screen are sequentially disposed inside the filter box.

[0009] Furthermore, the filtration accuracy of the first filter screen is greater than the filtration progress of the second filter screen.

[0010] Furthermore, the annular conduit is located at the top of the inner cavity of the washing machine casing, and the annular conduit is fixedly connected to the washing machine casing. The angle between the spray direction of the nozzle and the vertical direction is 20 to 30 degrees.

[0011] In the above technical solution, the lint filtering mechanism for a fully automatic washing machine provided by this utility model has the following beneficial effects:

[0012] 1. This utility model uses a water pump to draw water to the top of the washing machine and sprays it into the washing machine through a nozzle, thereby forming a burst of water flow, which promotes more even mixing of laundry detergent and water, resulting in better washing effect. By installing a filter component on the water pipe, it collects the lint left in the water during the washing process, preventing the lint from being discharged into the sewer and causing sewer blockage.

[0013] 2. By installing a one-way valve in the water pipe, the water can only flow in one direction, preventing the backflow of lint collected in the filter assembly.

[0014] 3. The filter box is slidably installed inside the filter housing. When it is necessary to process the collected lint, simply slide the filter box out of the filter housing to clean the first and second filter screens. The dual-layer filtration design allows for more efficient filtration.

[0015] 4. By arranging the liquid passages at an angle, with adjacent liquid passages tilted in opposite directions, the strong vortex generated when the washing machine rotates the impeller in both directions during the washing of clothes can impact the drainage holes and enter between the inner and outer drums, promoting water flow.

[0016] It should be understood that the foregoing general description and the following detailed description are exemplary and illustrative only, and are not intended to limit this disclosure.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0026] Please see Figures 1-4 A lint filtering mechanism for a fully automatic washing machine includes: a washing machine outer shell 1, an inner drum 3, an outer drum 4, and a pulsator 5. The pulsator 5 is located at the bottom of the inner drum 3. The pulsator 5 has inclined drainage holes 51, and the inclination directions of adjacent drainage holes 51 are opposite. The inner drum 3 has liquid passage holes 31, which are located below the drainage holes 51 and are interconnected. The lower end of the outer drum 4 is fixedly connected to a water pipe 8, and a water pump and a filter assembly are installed on the water pipe 8. The other end of the water pipe 8 is connected to an annular guide tube 6, and multiple nozzles 61 are arrayed at the bottom of the annular guide tube 6.

[0027] Specifically, a water inlet pipe 11 for water intake is fixedly connected to the top of the washing machine outer shell 1, and the cover 2 is the cover of the washing machine outer shell 1. When the detergent and clothes are put into the inner drum 3, the washing machine is started. The drive assembly 7 drives the impeller 5 to rotate in both directions to wash the clothes. The vortex formed by the impeller 5 causes the clothes to tumble, bend, rub, and squeeze continuously, and drives the water flow to the drain hole 51. The water flow enters between the inner drum 3 and the outer drum 4 through the drain hole 51 and the liquid passage hole 31. Under the action of the water pump, the water flow is delivered to the annular guide tube 6 through the water pipe 8 and sprayed out by the nozzle 61, so that the water flow sprays on the constantly tumbling clothes, making the water flow and detergent mix more evenly. The water flow spraying on the clothes also speeds up the washing process and improves the washing efficiency. After the washing is finished, under the action of the clutch in the drive assembly 7, the motor in the drive assembly 7 drives the inner drum 3 to rotate, and spin-dry the clothes in the inner drum 3.

[0028] Furthermore, the outer tub 4 is fixedly connected to the outer casing 1 of the washing machine, and the outer tub 4 is fitted over the inner tub 3, with the bottom of the inner cavity of the outer tub 4 being funnel-shaped.

[0029] For details, please refer to Figure 1 and Figure 3 The bottom of the inner cavity of the outer cylinder 4 is divided into two halves, and each half is set in a funnel shape so that the water flow gathers at the bottom of the funnel and flows to the water pipe 8, which facilitates the water pump to draw water between the outer cylinder 4 and the inner cylinder 3.

[0030] Furthermore, a one-way valve 81 is installed inside the water pipe 8, and the one-way valve 81 is located between the outlet of the outer cylinder 4 and the filter assembly.

[0031] For details, please refer to Figure 3 and Figure 4 By installing a one-way valve 81 inside the water pipe 8, the water flow can only flow in one direction, thus preventing the backflow of lint collected in the filter assembly.

[0032] Furthermore, the filter assembly includes a filter housing 82, which is fixedly connected to the washing machine housing 1. A filter box 9 is slidably disposed inside the filter housing 82. A first filter screen 91 and a second filter screen 92 are sequentially disposed inside the filter box 9. The filtration accuracy of the first filter screen 91 is greater than that of the second filter screen 92.

[0033] Specifically, by installing a filter assembly on the water pipe 8, lint remaining in the water during the washing process is collected. When the water flows through the filter assembly, it first passes through the second filter screen 92, then through the first filter screen 91 and enters the water pump. The double-layer filtration setup makes the filtration effect more effective, better protects the water pump and the nozzle 61, and makes the washing machine more capable of removing lint.

[0034] Furthermore, the annular conduit 6 is located at the top of the inner cavity of the washing machine outer shell 1. The annular conduit 6 is fixedly connected to the washing machine outer shell 1, and the angle between the spray direction of the nozzle 61 and the vertical direction is 20 to 30 degrees.

[0035] For details, please refer to Figure 2 The angle between the spray direction of nozzle 61 and the vertical direction depends on the size of the washing machine. The purpose is to ensure that the water jet from nozzle 61 is sprayed onto the clothes being washed.

[0036] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
