Description

Technical Field

[0001] The present invention relates to the technical field of clothing processing devices, and more specifically, to a composite cleaning mechanism, a clothing processing device, and a control method for the clothing processing device. Background Art

[0002] Currently, most washing machines with drying function have rear air inlets, which heat the air in the cold shower duct and then send it into the washing and drying drum to achieve the drying function. Clothes made of different fabrics will produce various types of lint or threads during the drying process, so an air filter is installed at the connection between the drying duct and the outer drum.

[0003] Existing air filters are usually single mesh plane structures, which can prevent some lint from entering the dryer. However, if a large amount of lint accumulates and adheres to the filter and cannot be removed in time, it will cause the air duct to be blocked, affecting the drying effect. The lint may even enter the heated dryer and cause a fire, posing a certain safety hazard. Summary of the Invention

[0035] With the improvement of people's living standards, clothes processing devices have already become one of the indispensable household appliances in daily life.

[0036] On the one hand, when the clothes processing device in the prior art dries clothes, clothes made of different fabrics in the washing and drying drum will produce various types of lint or thread ends during the drying process, so a filter 2 is set in the external drying duct 1 between the drying duct and the outer drum to filter out some of the lint or thread ends and other debris. However, in actual use, the accumulation of debris will affect the ventilation performance of the filter 2, and thus affect the drying effect of the clothes processing device.

[0037] Based on this, Figure 1-Figure 5 As shown, the composite cleaning mechanism according to an embodiment of the present invention is applied to a filter device, which includes a filter screen 2, including:

[0038] The vibration cleaning assembly includes: a vibration motor 7, a vibration connecting rod 10 and a vibration member 4. One end of the vibration connecting rod 10 is connected to the output end of the vibration motor 7, and the other end is connected to the vibration member 4. The vibration member 4 is in contact with the surface of the filter 2 and is used to vibrate and clean the filter 2.

[0039] The spray cleaning component includes: a water inlet pipe 5 and a spray head 3. One end of the water inlet pipe 5 is used to connect with an external water source, and the other end is connected with the spray head 3. The spray head 3 is arranged above the filter screen 2, and the spray head 3 is used to spray and clean the filter screen 2.

[0040] Specifically, the clothes processing device may be a washer-dryer with a drying function.

[0041] The vibration motor 7 can make the vibration part 4 vibrate through the vibration connecting rod 10, and the vibration part 4 is in contact with the surface of the filter 2. When the vibration part 4 vibrates, it can drive the filter 2 to vibrate together. The vibration of the filter 2 itself can shake off the debris between the filter 2, playing a certain cleaning role.

[0042] The spray head 3 is above the filter screen 2 and can spray cleaning liquid onto the filter screen 2. The water pressure and the characteristics of the cleaning liquid can remove the debris on the filter screen 2 and play a certain cleaning role on the filter screen 2.

[0043] The vibration cleaning component and the spray cleaning component can be used together or alternately for cleaning. First, the filter screen 2 is sprayed and cleaned by the spray cleaning component, and then the filter screen 2 is vibrated and cleaned by the vibration cleaning component. The cleaning is performed alternately in this way. During the first spray cleaning, some dirt can be taken away by water pressure and cleaning liquid. When the first spray cleaning is completed and the vibration cleaning begins, some stubborn debris attached to the filter screen 2 can be loosened, and then the debris can be quickly taken away by the second spray cleaning. This reciprocating process can improve the cleaning efficiency of the filter screen 2 and quickly remove dirt, lint and other debris on the surface of the filter screen 2.

[0044] Moreover, when the vibration cleaning component vibrates the filter 2, the water film between the grids of the filter 2 can be destroyed to prevent the water film from affecting the ventilation performance of the filter 2, thereby keeping the drying air in the drying duct unobstructed and ensuring the drying efficiency of the clothes processing device.

[0045] According to the clothing processing device of an embodiment of the present invention, the filter 2 arranged between the outer drum of the clothing processing device and the drying duct can be spray-cleaned and vibrated-cleaned respectively by the spray cleaning component and the vibration cleaning component. The filter 2 can be effectively cleaned by alternating spray cleaning and vibration cleaning, which can not only quickly remove debris on the filter 2, but also destroy the water film on the filter 2 produced by spray cleaning by vibration cleaning, thereby avoiding the water film affecting the ventilation of the filter 2, keeping the drying air in the drying duct unobstructed, and ensuring the drying efficiency.

[0046] In some embodiments, the vibration member 4 is disposed around the periphery of the filtering surface of the filter screen 2 , and the vibration member 4 coincides with the center line of the filter screen 2 .

[0047] Specifically, the vibrator 4 can be a hollow annular body, the outer diameter of the vibrator 4 can be the same as the diameter of the filter 2, the filter 2 can be a circular mesh plane structure, the center of the vibrator 4 and the center of the filter 2 are both on the same vertical line, the two surfaces of the filter 2 are filtering surfaces, which can filter out debris, and the vibrator 4 is arranged around the outermost circle of the filtering surface and can be in contact with the surrounding side of the filter 2, so as to better drive the filter 2 to vibrate while minimizing the impact on the ventilation performance of the filter 2, so that most areas of the filtering surface are not blocked and the drying air can pass normally, thereby avoiding affecting the drying performance of the clothing processing device.

[0048] In some embodiments, the vibration frequency of the vibration motor 7 is set to the resonance frequency of the filter 2 .

[0049] Specifically, the filter 2 itself has a resonant frequency, which is the frequency at which the component (or structure) can produce the maximum response. By adjusting the vibration frequency of the vibration motor 7 so that the vibration frequency of the vibration motor 7 is the same as the resonant frequency of the filter 2, the filter 2 can be vibrated to the maximum extent, thereby improving the vibration cleaning effect. Due to the influence of the structure, the resonant frequencies of the outer drum structure and the filter structure must be different, and the resonant frequency of the outer drum of the clothing processing device can also be avoided.

[0050] In some embodiments, the spray center of the spray head 3 coincides with the center line of the filter screen 2 .

[0051] Specifically, as attached Figure 4The dotted line is a schematic curve of the spray head 3 spraying the cleaning liquid. The spray head 3 can be a circular sprayer. The spray head 3 can spray the cleaning liquid evenly. When the spray head 3 sprays the cleaning liquid, the central area is the spray center. The spray center coincides with the center line of the filter 2, so that the sprayed cleaning liquid can fall on the middle position of the filter 2, making the spray cleaning effect more uniform and avoiding dead corners.

[0052] Preferably, the filter screen 2 may be an upwardly convex arc structure, and the sprayed cleaning liquid may flow from the center of the filter screen 2 to the surrounding areas, thereby improving the cleaning effect, and the convex portion of the filter screen 2 may also better contact with the vibrating member 4.

[0053] The embodiment of the present application further provides a filtering device, which is applied to a clothes processing device. The clothes processing device includes an external drying duct 1 for connecting the drying duct and the outer drum. The external drying duct 1 extends longitudinally and includes: a filter 2 and the aforementioned composite cleaning mechanism;

[0054] Among them, the filter screen 2 is arranged horizontally in the external drying air duct 1, the vibration motor 7 is arranged on the outer wall of the external drying air duct 1, the vibrator 4 is attached to the upper surface of the filter screen 2, and the spray head 3 is arranged above the filter screen 2.

[0055] Specifically, the filtering device may include a filter screen 2 and a frame for fixing the filter screen 2. The filter screen 2 is fixed in the external drying air duct 1 through the frame, and can filter the drying air circulating in the external drying air duct 1 to remove some lint, thread ends and other debris. The vibration motor 7 is arranged on the outer wall of the external drying air duct 1 and can be fixed by other components or fixed to the outer wall of the external drying air duct 1 by bolts.

[0056] In some embodiments, the filter screen 2 is in the shape of an upwardly convex arc surface.

[0057] Specifically, the upwardly protruding arc surface can make the filter 2 itself have a height difference, so that the cleaning liquid sprinkled by the spray cleaning component falls on the center of the filter 2 and flows to the surroundings under the action of gravity instead of dripping directly downward. This can increase the time that the cleaning liquid remains on the filter 2, improve the cleaning effect, and make the spray cleaning more comprehensive, avoiding dead corners.

[0058] The upwardly protruding arc surface can also better contact with the vibrating member 4, ensuring the vibration effect of the vibrating member 4 on the filter screen 2.

[0059] In some embodiments, a sound insulation box 6 is provided on the outer wall of the external drying air duct 1 , sound insulation cotton is provided on the inner wall of the sound insulation box 6 , and a vibration motor 7 is provided in the sound insulation box 6 .

[0060] Specifically, the sound insulation box 6 can be a rectangular box body, which can be fixed to the outer wall of the external drying duct 1 by bolts. The sound insulation box 6 can play a certain protective role for the vibration motor 7, and the vibration motor 7 can be fixed in the sound insulation box 6 instead of on the external drying duct 1, which can reduce the impact of the vibration motor 7 on the external drying duct 1.

[0061] Sound insulation cotton is also provided on the inner wall of the sound insulation box 6. The sound insulation cotton can be glued and connected to the inner wall of the sound insulation box 6 by glue. The sound insulation cotton can make the sound insulation box 6 have a sound insulation function. The vibration motor 7 is arranged in the sound insulation box 6 with a sound insulation function, which can reduce the noise generated by the vibration motor 7.

[0062] In some embodiments, a protective box 9 is provided on the top of the sound insulation box 6 , and part of the pipe body of the water inlet pipe 5 is provided in the protective box 9 .

[0063] Specifically, the protective box 9 can be a rectangular box body, which can be fixed on the top of the sound insulation box 6. The water inlet pipe 5 passes through the protective box 9 from the outside and is connected to the sprinkler head 3. The protective box 9 can play a certain protective role on the connection area between the water inlet pipe 5 and the sprinkler head 3, and can also make the overall components more concentrated and have better aesthetics.

[0064] The embodiment of the present application further provides a clothes processing device, comprising: a drying duct, an outer drum, an external drying duct 1 and the aforementioned filtering device;

[0065] The two ends of the external drying air duct 1 are respectively connected to the drying air duct and the outer cylinder, and the filtering device is arranged on the external drying air duct 1 .

[0066] Specifically, the clothes processing device can be a washer-dryer with a drying function, and the drying air duct is connected to the outer drum through the external drying air duct 1 to realize the circulation of hot air to dry the clothes.

[0067] In some embodiments, a mounting hole is provided on the side wall of the external drying air duct 1 , the vibration connecting rod 10 is inserted into the mounting hole, and a buffer layer 8 is filled between the vibration connecting rod 10 and the mounting hole.

[0068] Specifically, the mounting hole and the vibration connecting rod 10 are filled with a buffer layer 8, which can be a rubber ring. The rubber ring can prevent the vibration connecting rod 10 from hitting the external drying duct 1 during vibration. The rubber ring can also provide certain support for the vibration connecting rod 10, thereby increasing the service life of the vibration connecting rod 10.

[0069] An embodiment of the present application further provides a method for controlling a clothes processing device, comprising: cleaning the filter 2 by continuously alternating spray cleaning and vibration cleaning.

[0070] Specifically, the filter 2 can be cleaned alternately by the vibration cleaning component and the spray cleaning component. The filter 2 is first sprayed and cleaned by the spray cleaning component, and then the filter 2 is vibrated and cleaned by the vibration cleaning component. The cleaning is performed alternately in this way. During the first spray cleaning, some dirt can be taken away by water pressure and cleaning liquid. When the first spray cleaning is completed and the vibration cleaning begins, some stubborn debris attached to the filter 2 can be loosened, and then the debris can be quickly taken away by the second spray cleaning. This reciprocating process can improve the cleaning efficiency of the filter 2 and quickly remove dirt, lint and other debris on the surface of the filter 2.

[0071] In some embodiments, the last action when stopping cleaning the filter 2 is vibration cleaning.

[0072] Specifically, in the alternating cleaning steps of vibration cleaning and spray cleaning, vibration cleaning is used before the final stop of cleaning. This can destroy the water film remaining in the filter 2 before completing the cleaning, thereby preventing the water film from affecting the ventilation performance of the filter 2 and affecting the drying efficiency of the clothing processing device.
