Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of clothes processing equipment, and particularly provides a clothes processing equipment. BACKGROUND

[0002] With the continuous development of science and technology, clothes processing equipment such as washing machines, clothes dryers and washing-drying integrated machines has become a common household appliance in people's lives. In the prior art, taking the washing-drying integrated machine as an example, thread scraps will appear during the drying process of clothes, and too many thread scraps will easily block the fan and heating pipe and other components, so that the drying effect is not ideal or the machine fails, and therefore it is necessary to filter and collect the thread scraps. A traditional thread scrap collection method is to set a thread scrap filter screen in the drying air duct, but the filtering effect of the thread scrap filter screen is limited, and the thread scrap filter screen will be covered with thread scraps in a very short time. The thread scrap filter screen arranged in the air duct is not convenient for effectively collecting and cleaning the thread scraps, which greatly reduces the user experience.

[0003] Correspondingly, there is a need in the art for a new clothes processing equipment to solve the problems existing in the prior art. SUMMARY

[0004] The present application aims to solve the above technical problems, i.e. to solve the problem of too many thread scraps in the drying process of the existing clothes processing equipment and the difficulty in collecting and cleaning the thread scraps.

[0005] The present application provides a clothes processing equipment, which comprises a box body, a clothes processing drum and a drying air duct arranged in the box body, both ends of the drying air duct being communicated with the clothes processing drum, a filter assembly allowing airflow to pass through and capable of filtering thread scraps being arranged inside the drying air duct, the filter assembly comprising a filter member, a cleaning member and a collection member, the cleaning member comprising a rotating shaft located at the windward side of the filter member and a plurality of curved panels distributed along the circumference of the rotating shaft, the curved panels being in contact with the windward surface of the filter member near the side edges of the filter member, so that the curved panels rotate around the axis of the rotating shaft under the action of the airflow to scrape off the thread scraps on the filter member, and the collection member is arranged below the cleaning member for containing the thread scraps scraped off from the filter member.

[0006] Through the above arrangement, in the drying stage of the clothes treatment equipment, lint moves in the drying air duct along with the airflow and is intercepted by the filtering member. Under the action of the airflow circulating in the drying air duct, the curved panel rotates around the rotating shaft, thereby scraping off the lint attached to the filtering member. The scraped-off lint gathers into a group on the surface of the curved panel and falls into the collecting member when the lint gathers to a certain extent so that the gravity it receives is greater than the buoyancy it receives. This avoids the situation that the lint blocks the drying air duct or reattaches to the clothes during the drying process. The user does not need to manually clean the lint on the filtering member after the drying is completed, thereby improving the lint filtering efficiency and also improving the user experience. Through the above ingenious arrangement, the curved panel can rotate around the rotating shaft by means of the action of the airflow in the drying air duct in the drying stage, thereby scraping off the lint on the filtering member, without the need to set a driving device.

[0007] In the preferred technical solution of the above clothes treatment equipment, a scraping hook structure is formed on the side edge of the curved panel that is in contact with the windward surface of the filtering member.

[0008] Through the above arrangement, when the curved panel rotates around the rotating shaft under the action of the airflow, the scraping hook structure on the side edge of the curved panel that is in contact with the windward surface of the filtering member can more effectively scrape off the lint attached to the filtering member, so that the lint attached to the filtering member can be cleaned more timely, thereby further improving the filtering effect of the filtering member.

[0009] In the preferred technical solution of the above clothes treatment equipment, the rotating shaft is sleeved with a sleeve, a plurality of the curved panels are fixedly connected or integrally formed with the sleeve, a limiting member is arranged at one end of the rotating shaft away from the filtering member, and an elastic member is arranged between the limiting member and the sleeve to be sleeved on the rotating shaft, so as to make the side edge of the curved panel close to the filtering member always in contact with the windward surface of the filtering member under the action of the elastic member.

[0010] Through the above arrangement, the limiting member and the elastic member can make the side edge of the curved panel close to the filtering member always in contact with the windward surface of the filtering member, thereby avoiding the situation that the side edge of the curved panel cannot effectively scrape off the lint on the filtering member after being worn out due to long-time use, so that the cleaning member can effectively clean the lint on the filtering member for a long time.

[0011] In the preferred technical scheme of the above-mentioned clothes treatment equipment, the drying air duct comprises a vertical air duct and a horizontal air duct in communication with the upper end of the vertical air duct, the filter member is arranged at a position close to the vertical air duct in the horizontal air duct, the cleaning member and the collection member are both located in the vertical air duct, the collection member is arranged at a position close to the first side inner wall in the vertical air duct, and the second side inner wall of the vertical air duct relative to the first side inner wall has a passage allowing airflow to pass between the second side inner wall and the collection member, the collection member comprises a base body, a U-shaped passage is formed in the base body, an upper surface of the base body is formed with a lint collection port located below the filter member, a first end of the U-shaped passage is in communication with the lint collection port, and a second end of the U-shaped passage is in communication with the clothes treatment drum, and in the use state, the U-shaped passage stores liquid to block the U-shaped passage.

[0012] Through the above arrangement, in the drying stage of the clothes treatment equipment, the airflow can pass through the passage between the second side inner wall of the vertical air duct relative to the first side inner wall and the collection member, so that the lint can be attached to the filter member under the action of the airflow, and the lint removed by the curved panel can directly fall into the lint collection port, and then enter the first end of the U-shaped passage in communication with the lint collection port. The liquid stored in the U-shaped passage can wet the removed lint, so as to avoid the airflow near the lint collection port blowing up the lint in the U-shaped passage. In the use state, the liquid stored in the U-shaped passage blocks the U-shaped passage, avoiding the situation that the airflow in the drying air duct causes airflow in the U-shaped passage due to the negative pressure generated near the lint collection port in the process of flowing, so as to avoid the situation that the lint is blown up by the airflow in the U-shaped passage and cannot accurately fall into the U-shaped passage in the process of falling into the U-shaped passage. Even in the case that the cleaning member fails to effectively remove the lint on the filter member and causes the filter member to be completely blocked, the airflow entering the drying air duct will enter the U-shaped passage from the first end of the U-shaped passage, blow the liquid in the U-shaped passage into the clothes treatment drum together with the lint, and then be discharged through the exhaust passage in the clothes treatment drum, so as to complete the filtering, collecting and discharging of the lint, improve the lint filtering efficiency, and improve the user's experience.

[0013] In the preferred technical scheme of the above-mentioned clothes treatment equipment, a vertical connecting passage is formed between the lint collection port and the first end of the U-shaped passage, and the cross-sectional area of the connecting passage decreases from top to bottom.

[0014] Through the above arrangement, the area of the thread scrap filtering port is larger than the cross-sectional area of the U-shaped channel, so that the scraped thread scrap can more conveniently fall into the thread scrap collecting port and along the connecting channel into the U-shaped channel under the action of gravity, facilitating the collection of thread scrap and improving the thread scrap collection effect. In addition, when the airflow velocity in the drying air duct is large and a large negative pressure is generated at the thread scrap collecting port, the connecting channel with the decreasing cross-sectional area from top to bottom can make the liquid in the U-shaped channel flow into the connecting channel at a lower height under the action of negative pressure, so that the U-shaped channel reaches the connected state, thereby avoiding the liquid in the U-shaped channel from entering the drying air duct from the thread scrap collecting port under the action of negative pressure, and avoiding the thread scrap from being contaminated and adhered in the drying air duct.

[0015] In the preferred technical scheme of the above laundry treating apparatus, the cross-sectional area of the connecting channel gradually decreases from top to bottom.

[0016] Through the above arrangement, the thread scrap in contact with the inner wall of the connecting channel more smoothly slides into the U-shaped channel, so that the scraped thread scrap can be more conveniently and quickly collected.

[0017] In the preferred technical scheme of the above laundry treating apparatus, the collecting member includes a base body, an upper surface of the base body is formed with a thread scrap collecting port located below the filtering member, and the base body is formed with a containing cavity located below the thread scrap collecting port, and in the use state, the containing cavity contains liquid.

[0018] Through the above arrangement, after the thread scrap attached to the filtering member is scraped, it can directly fall into the thread scrap collecting port and then into the containing cavity to complete the collection of thread scrap, without the need for manual collection by the user.

[0019] In the preferred technical scheme of the above-mentioned clothes treatment equipment, the filter assembly comprises a first filter assembly and a second filter assembly, the first filter assembly comprises a first filter member, a first cleaning member and a first collection member, the second filter assembly comprises a second filter member, a second cleaning member and a second collection member; the drying air duct comprises a vertical air duct and a horizontal air duct in communication with the upper end of the vertical air duct, the first filter member is arranged at a position close to the vertical air duct in the horizontal air duct, the first cleaning member and the first collection member are both located in the vertical air duct, the first collection member is arranged at a position close to the first side inner wall in the vertical air duct, and the second side inner wall of the vertical air duct relative to the first side inner wall has a passage allowing airflow to pass between the second side inner wall and the first collection member, the first collection member comprises a first base body, a U-shaped passage is formed in the first base body, a first lint collection port located below the first filter member is formed on the upper surface of the first base body, the first end of the U-shaped passage is in communication with the first lint collection port, the second end of the U-shaped passage is in communication with the clothes treatment drum, and in the use state, the U-shaped passage contains liquid; the second collection member comprises a second base body, a second lint collection port located below the second filter member is formed on the upper surface of the second base body, and a containing cavity located below the second lint collection port is formed on the second base body, and in the use state, the containing cavity contains liquid.

[0020] Through the above arrangement, the clothes treatment equipment forms a complete set of two-stage lint filtering system, in the drying stage, the lint in the drying air duct can be filtered and cleaned twice under the action of airflow, which can avoid the situation that bacteria breed in the drying air duct due to the residual lint after the lint in the drying air duct is filtered once, or the lint is blown back into the clothes treatment drum and attached to the clothes, improve the lint filtering effect and efficiency, and optimize the user experience.

[0021] In the preferred technical scheme of the above-mentioned clothes treatment equipment, the collection member is further provided with a flushing device for removing the lint in the collection member.

[0022] Through the above arrangement, after the scraped lint falls into the collection member, the collection member can be flushed with water by the flushing device to discharge the lint in the collection member, without the need for the user to manually clean the lint in the collection member.

[0023] In the preferred technical scheme of the above-mentioned clothes treatment equipment, the filter assembly is detachably connected with the drying air duct.

[0038] Reference will be made below to Figures 1 to 6 The clothes treatment equipment of the present application is described in detail. Among them, Figure 1 is a structure diagram of the outer drum and the drying air duct assembly of the drum-type washing and drying integrated machine in an embodiment of the present application; Figure 2 is a sectional view of the outer drum and the drying air duct assembly of the drum-type washing and drying integrated machine in an embodiment of the present application Figure 1 ; Figure 3 is Figure 2 an enlarged view of part A in Figure 4 is a sectional view of the first curved panel in an embodiment of the present application; Figure 5 is a sectional view of the outer drum and the drying air duct assembly of the drum-type washing and drying integrated machine in an embodiment of the present application Figure 2 ; Figure 6 is Figure 5 an enlarged view of part B in

[0039] Specifically, as Figures 1 to 4As shown, the drum washer-dryer includes a cabinet (not shown in the figure), the cabinet is provided with an outer drum 1 and a rotatable drum (not shown in the figure) arranged in the outer drum 1, and a drying air duct is arranged outside the outer drum 1, wherein both ends of the drying air duct are communicated with the drum, the drying air duct includes a vertical air duct 21 and a horizontal air duct 22 communicated with the upper end of the vertical air duct 21, the cross section of the vertical air duct 21 and the horizontal air duct 22 is square, and a first filter assembly is detachably arranged in the vertical air duct 21 for filtering lint flowing with the airflow in the drying air duct, and facilitating the inspection, maintenance and replacement of the first filter assembly. The first filter assembly includes a first filter member, the first filter member includes a first bracket 31 and a first annular filter screen 32, the first bracket 31 is fixed in the vertical air duct 21 by screwing, clamping or bonding, etc., and the first annular filter screen 32 is fixed on the first bracket 31 by screwing or clamping, etc., and the first annular filter screen 32 is in a horizontal state. The first annular filter screen 32 can be made of a mesh cloth with small density, or a grid structure, and the material and density of the first annular filter screen 32 can be flexibly set by the person skilled in the art in actual application. The first filter assembly further includes a first cleaning member, the first cleaning member includes a first rotating shaft 41, the center of the first bracket 31 is formed with a clamping groove, one end of the first rotating shaft 41 is vertically clamped in the clamping groove of the first bracket 31, and a first sleeve 42 is sleeved on the first rotating shaft 41. Figure 3 and Figure 4 As shown, the first sleeve 42 is integrally formed with a plurality of first curved panels 51, the side edges of the first curved panels 51 are in contact with the windward surface of the first annular filter screen 32, and a first scraping hook 52 is formed on the contact part of the first curved panel 51, so that when the first curved panel 51 rotates tightly on the first annular filter screen 32 under the driving of the airflow, the first scraping hook 52 can scrape off the lint attached on the first annular filter screen 32, a part of external threads is arranged on the other end of the first rotating shaft 41, a first nut 43 is screwed on the external threads of the first rotating shaft 41 to realize limiting, and a first spring 44 is sleeved on the first rotating shaft 41 between the first nut 43 and the first sleeve 42, so that the side edges of the plurality of first curved panels 51 close to the first annular filter screen 32 are always in contact with the windward surface of the first annular filter screen 32 under the action of the first spring 44, thereby scraping off the lint on the first annular filter screen 32.

[0040] It should be noted that the first support 31 and the first annular filter screen 32 can be integrally arranged, facilitating installation and disassembly and replacement. In addition, the first sleeve 42 and the plurality of first curved panels 51 can also be detachably connected, such as clamping the first curved panel 51 on the first sleeve 42 to achieve connection. The first scraping hook 52 can be a structure extending outwardly from the side edge of the first curved panel 51, or a scraping hook fixed on the side edge of the first curved panel 51. The above two setting modes can be freely selected, as long as the first scraping hook 52 can scrape the lint on the first annular filter screen 32 when the first curved panel 51 is tightly attached to the first annular filter screen 32 and rotates. Forming the first scraping hook 52 on the part where the first curved panel 51 contacts the first annular filter screen 32 is only a preferred setting mode, which can be adjusted in actual application. For example, in a feasible setting mode, the first curved panel 51 can also not be provided with the first scraping hook 52, and the lint attached to the first annular filter screen 32 can be scraped off by the side edge of the first curved panel 51.

[0041] As shown in Figure 3 , a first collection member in communication with the outer cylinder 1 is arranged below the first annular filter screen 32. A first lint collection opening 62 located below the first annular filter screen 32 is formed on the upper surface of a first base body 61 of the first collection member. A containing cavity 63 located below the first lint collection opening 62 is formed on the first base body 61. Specifically, the first base body 61 is recessed from the first lint collection opening 62 on the upper surface to form a groove-shaped structure. A first water outlet 65 in communication with the outer cylinder 1 is formed on the side wall of the groove-shaped structure close to the outer cylinder 1. The containing cavity 63 is formed in the groove-shaped structure. The first lint collection opening 62, the containing cavity 62, and the first water outlet 65 are in communication to form part of the drying air duct. A first water flushing opening 64 is arranged on the side wall of the groove-shaped structure opposite to the first water outlet 65. The first water flushing opening 64 is connected with the water supply pipeline of the washer-dryer all-in-one machine. During the drying process, the containing cavity 63 stores a small amount of water supplied by the first water flushing opening 64, which can wet the lint balls falling into it and prevent the scraped lint balls from being blown up by the airflow. When the drying is completed, a large amount of water is discharged into the containing cavity 63 through the first water flushing opening 64 to flush the collected lint in the containing cavity 63 to the outer cylinder 1 from the first water outlet 65, and finally discharged through the drain pipe connected to the bottom of the outer cylinder 1.

[0042] As shown in Figure 5 and Figure 6 , a second filter assembly is also detachably arranged in the drying air duct downstream of the first filter assembly, so as to perform secondary filtration on the lint remaining in the airflow after being filtered by the first filter assembly. The second filter assembly is detachably arranged in the drying air duct, so as to facilitate inspection, maintenance and replacement of the second filter assembly.

[0043] Specifically, the second filtration assembly includes a second filter component, a second collection component, and a second cleaning component. The second filter component is located in the horizontal air duct 22 near the vertical air duct 21. The second filter component includes a second support and a second annular filter screen (not shown in the figure, but the specific structure can be found in [reference needed]). Figure 3 The first support 31 and the first annular filter 32 are structurally connected. The second support is fixed to the inner wall of the horizontal air duct 22 by screwing, snapping, or bonding. The second annular filter is fixed to the second support by screwing or snapping, and the second annular filter is in a vertical position. The second annular filter can be made of a high-density mesh or have a grid structure. Those skilled in the art can flexibly set the material and density of the second annular filter in practical applications. The second cleaning component is horizontally arranged on the windward side of the second annular filter and located within the vertical air duct 21. The second cleaning component includes a second rotating shaft 71. A groove is formed in the center of the second support. One end of the second rotating shaft 71 is vertically snapped into the groove of the second support. A second sleeve 72 is fitted onto the second rotating shaft 71. Figure 6 As shown, multiple second curved panels 75 are fixed on the second sleeve 72. The side edges of the second curved panels 75 contact the windward surface of the second annular filter screen, and second scrapers are formed at the contact points of the second curved panels 75 (the specific structure can be found in [reference]). Figure 4 The first scraper hook 52 in the middle allows the second curved panel 75 to scrape off the lint adhering to the second annular filter screen when it rotates tightly against the second annular filter screen under the drive of airflow. A portion of the external thread is provided on the other end of the second rotating shaft 71, and the second nut 73 is screwed onto the external thread of the second rotating shaft 71 to achieve a limit. A second spring 74 is provided between the second nut 73 and the second sleeve 72 and sleeved on the second rotating shaft 71, so that under the action of the second spring 74, the side edges of the multiple second curved panels 75 near the second annular filter screen are always in contact with the windward side of the second annular filter screen, thereby scraping off the lint on the second annular filter screen.

[0044] It should be noted that the second support and the second annular filter screen can be integrally arranged, facilitating installation and disassembly and replacement. In addition, the second sleeve 72 and the plurality of second curved panels 75 can be detachably connected, such as clamping the second curved panel 75 on the second sleeve 72 to achieve connection. The second scraping hook can be a structure formed by extending outwardly from the side edge of the second curved panel 75, or a scraping hook fixed on the side edge of the second curved panel 75. The above two modes can be freely selected, as long as the second scraping hook can scrape the lint on the second annular filter screen when the second curved panel 75 is tightly attached to the second annular filter screen. Forming the second scraping hook on the part of the second curved panel 75 contacting the second annular filter screen is only a preferred arrangement, which can be adjusted in actual application, such as in a feasible arrangement, the second curved panel 75 can also not be provided with the second scraping hook, and the lint attached to the second annular filter screen can be scraped off by the side edge of the second curved panel 75.

[0045] A second collecting member in communication with the outer cylinder 1 is arranged below the second annular filter screen, the second collecting member is arranged on the inner wall close to the direction of the outer cylinder 1 in the vertical air duct 21, and the inner wall of the vertical air duct 21 close to the direction of the outer cylinder 1 has a passage allowing airflow to pass between the second collecting member, a U-shaped passage 82 is formed in the second base body 81 of the second collecting member, the upper surface of the second base body 81 forms a second lint collecting port 83 below the second filter member, the first end of the U-shaped passage 82 is in communication with the second lint collecting port 83 through a connecting passage 84, the cross-sectional area of the connecting passage 84 gradually decreases from top to bottom, forming a funnel-shaped passage, so that the scraped lint can more smoothly fall into the U-shaped passage 82 along the inner wall of the connecting passage 84, the second flushing port 85 is arranged in the vertical air duct 21 close to the second lint collecting port 83, the second flushing port 85 is connected with the water supply pipeline of the washing-drying integrated machine, and the second water outlet 86 is arranged on the second end of the U-shaped passage 82, and the second water outlet 86 is in communication with the outer cylinder 1.

[0046] In the drying process, the residual lint after the first filtering can be further filtered by the second annular filter screen. Under the action of the airflow, the second curved panel 75 rotates around the second rotating shaft 71, and the second scraping hook is used to scrape off the lint attached to the second annular filter screen. When there is a large amount of lint to be scraped off, the lint can be gathered into a ball. When the weight of the lint ball is greater than the buoyancy it receives, the lint ball falls into the funnel-shaped connecting channel 84 and enters the U-shaped channel 82. The water in the U-shaped channel 82 can wet the lint ball, so that the lint ball is stored in the U-shaped channel 82. After the drying is completed, a large amount of water is discharged into the U-shaped channel 82 through the second water outlet 85 to flush the lint collected in the U-shaped channel 82 from the second water outlet 86 into the outer cylinder 1, and finally discharged through the drain pipe connected to the bottom of the outer cylinder 1. The water stored in the U-shaped channel 82 blocks the U-shaped channel 82, avoiding the situation that the airflow in the drying air duct causes negative pressure near the second lint collecting port 83, causing airflow in the U-shaped channel 82, thereby avoiding the situation that the lint is blown up by the airflow in the U-shaped channel 82 during the process of falling into the U-shaped channel 82, and cannot accurately fall into the U-shaped channel 82. Even if the second scraping hook fails to effectively remove the lint on the second annular filter screen, causing the second annular filter screen to be completely blocked, the airflow entering the vertical air duct 21 will enter the U-shaped channel 82 from the first end of the U-shaped channel 82, blowing the liquid and lint in the U-shaped channel 82 into the outer cylinder 1 and then discharging, thereby completing the second filtering, collecting and discharging of the lint.

[0047] It should be noted that the cross-sectional area of the connecting channel 84 can also be discontinuously reduced from top to bottom. At the same time, the cross-section of the vertical air duct 21 and the horizontal air duct 22 can also be circular or polygonal. At the same time, the specific structure and shape of the first filtering member and the second filtering member can also be adjusted accordingly according to the setting of the vertical air duct 21 and the horizontal air duct 22, so that the edges of the first filtering member and the second filtering member can filter the lint when installed. In addition, the first filtering assembly and the second filtering assembly in the drying air duct are only an exemplary setting mode, and multiple filtering assemblies can also be provided. The adjustment of the number and setting position of the filtering assemblies does not limit the protection scope of the present application. In addition, the U-shaped channel 82 and the containing cavity 63 store water, and the first water inlet 64 and the second water inlet 85 are connected with the water supply pipeline of the washer-dryer, which is only a specific setting mode. In actual application, adjustments can be made, such as setting a liquid storage tank on the washer-dryer, connecting the first water inlet 64 and the second water inlet 85 with the liquid storage tank, and storing water, a mixture of water and disinfectant, and other liquids in the liquid storage tank. In the use state, the U-shaped channel 82 and the containing cavity 63 can store a mixture of water and disinfectant, which can not only be used to flush out the lint, but also can inhibit the growth of bacteria. The first spring 44 and the second spring 74 in the above embodiment can also be replaced by a rubber sleeve or other suitable elastic members.

[0048] In another possible embodiment, only the first filter assembly or the second filter assembly of the above-described embodiments can be provided.

[0049] So far, the technical solutions of the present application have been described in combination with the preferred embodiments shown in the drawings, but it is easy for those skilled in the art to understand that the protection scope of the present application is obviously not limited to these specific embodiments.
