Description

A garment processing device and its lint filtering device Technical Field

[0001] This invention relates to the field of clothing processing technology, and in particular to a clothing processing device and its lint filtering apparatus. Background Technology

[0002] With the improvement of residents' living standards, existing washing machines not only need to meet the needs of washing, but also the need for drying clothes after washing. Washer-dryer combos have emerged to meet this need. The working principle of a washer-dryer combo is roughly as follows: air is heated by a heater and then enters the drum to heat the clothes. The air inside the drum becomes hot and humid, and then the moisture is condensed into water and collected in a water tank through a condensation system, forming a circulation that continuously removes moisture from the clothes to achieve the purpose of drying them. The heater can be, for example, an electric heater or an evaporator in a heat pump system.

[0003] The existing automatic lint filter in the drying process generates a large amount of lint during the middle and later stages of drying. If the lint covering the filter screen is not cleaned in time, the airflow circulation in the duct will be obstructed, and the drying efficiency will drop in real time. Only by cleaning the filter screen in a timely manner and keeping the duct unobstructed and the airflow stable can efficient drying be ensured. If users want to improve efficiency by cleaning the filter screen, they need to pause the program, wait for the temperature inside the drum to drop, and for the fan to stop before they can remove the filter screen for cleaning and restart the program, which is time-consuming and laborious.

[0004] In addition, some products are equipped with an automatic lint cleaning mechanism to automatically clean the lint on the filter screen. The lint automatically cleaned from the filter screen is usually stored in a lint collection box. When there is a lot of lint in the lint collection box, the lint collection box can be removed and the lint poured out.

[0005] However, when the drying program is running and the lint collection box has already stored some lint, a high-speed airflow in the duct may carry some of the lint stored in the lint collection box back into the duct, which will undoubtedly affect the drying effect of the clothes.

[0006] In view of this, the present invention is hereby proposed. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to overcome at least some of the shortcomings of the prior art and provide a lint filtering device for clothing processing equipment. By adding a top opening part to the lint cleaning component, when the cleaning part moves to the first end near the filter, the top opening part opens the flip cover at the lint inlet of the lint collection box, so that the lint cleaned at the front end of the cleaning part falls into the box assembly of the lint collection box through the lint inlet. When the cleaning part moves to the first end away from the filter, the flip cover closes the lint inlet. This not only achieves the purpose of automatic lint cleaning, but also avoids the situation where the high-speed airflow in the air duct carries some of the lint already stored in the lint collection box back into the air duct, which helps to improve the drying effect.

[0008] To solve the above-mentioned technical problems, the present invention provides a lint filtering device for clothing processing equipment, comprising:

[0009] The filter duct has a filter duct inlet and a filter duct outlet;

[0010] A filter is disposed in the air duct from the air inlet to the air outlet of the filter duct; and

[0011] A lint collection box, disposed at the first end of the filter, includes a box assembly having a lint inlet and a flip cover pivotally connected to the box assembly for opening and closing the lint inlet;

[0012] A lint cleaning assembly includes a cleaning section, a top opening section, and a drive mechanism. When the drive mechanism drives the cleaning section and the top opening section to move close to the first end of the filter, the top opening section opens the flip cover to open the lint inlet, allowing the lint cleaned by the front end of the cleaning section to fall into the housing assembly through the lint inlet.

[0013] In some embodiments, the drive mechanism includes a rotating shaft, a transmission unit, and a drive unit;

[0014] The rotating shaft is connected to the cleaning part and / or the top opening part, and the two ends of the transmission unit are respectively connected to the rotating shaft and the drive unit;

[0015] The drive unit drives the rotating shaft to reciprocate between the first and second ends of the filter via the transmission unit, thereby moving the cleaning section and the top opening section.

[0016] In some embodiments, the transmission unit includes a driving gear, a driven gear, and a swing arm;

[0017] The driving gear is connected to the drive unit, the driven gear meshes with the driving gear, and the swing arm connects the driven gear and the rotating shaft.

[0018] In some embodiments, the filter duct includes an upper duct and a lower duct that are snap-fitted together;

[0019] The bottom wall of the downdraft duct is constructed as an arc-shaped structure with an obstacle clearance installation space. The drive unit is located within the obstacle clearance installation space, and the transmission unit is located on the outside of the side wall of the downdraft duct. The side wall of the updraft duct and / or the downdraft duct is provided with an obstacle clearance groove to avoid the swing of the swing arm.

[0020] In some embodiments, the air inlet of the filter duct is disposed on the upper air duct, and the air outlet of the filter duct is disposed on the back plate of the lower air duct.

[0021] The lint collection box is connected to the portion of the downdraft located above the air outlet of the filter duct.

[0022] In some embodiments, a protective cover is provided on the side wall of the downdraft duct where the transmission unit is housed.

[0023] In some embodiments, the housing assembly includes an outer housing and an inner housing detachably disposed within the outer housing;

[0024] The outer casing is connected to the filter duct. The outer casing includes a body and a cover that is fastened to the body. The lint inlet is located on the side wall of the body, opposite to the first end of the filter, and higher than the inner casing so that lint falls into the inner casing.

[0025] In some embodiments, the shielding plate and the counterweight plate have a preset angle, and the free end of the counterweight plate is in contact with the side wall of the body opposite to the wire chip inlet.

[0026] In some embodiments, the counterweight plate has a guide opening, and the cover has a guide post passing through the guide opening on the side facing the main body. When the flip cover pivots relative to the main body, the guide post guides the movement direction of the counterweight plate.

[0027] The present invention also provides a garment processing device, including the lint filter according to the above.

[0028] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0029] (1) The lint filter device of the garment processing equipment provided by the present invention adds a top opening part to the lint cleaning component. When the cleaning part moves to the first end close to the filter, the top opening part opens the flip cover at the lint inlet of the lint collection box, so that the lint cleaned at the front end of the cleaning part falls into the box body component of the lint collection box through the lint inlet. When the cleaning part moves to the first end away from the filter, the flip cover closes the lint inlet. In this way, the purpose of automatically cleaning lint can be achieved, and the situation that the high-speed airflow in the air duct will bring some of the lint already stored in the lint collection box back into the air duct can be avoided, which helps to improve the drying effect.

[0030] (2) The lint filter device of the clothing processing equipment provided by the present invention uses gear transmission to drive the rotating shaft to reciprocate between the first end and the second end of the filter to drive the cleaning part and the top opening part to move. It has high transmission efficiency, long service life and reduces equipment failure rate.

[0031] (3) The lint filter device of the clothing processing equipment provided by the present invention improves the lint inlet covering effect by setting the flip cover as a baffle for covering the lint inlet and a counterweight plate connected to the baffle. The weight of the counterweight plate overcomes the pressure brought by the high-speed airflow in the air duct to the baffle. Attached Figure Description

[0046] It should be noted that these accompanying drawings and textual descriptions are not intended to limit the scope of the invention in any way, but rather to illustrate the concept of the invention to those skilled in the art by referring to specific embodiments. Detailed Implementation

[0047] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0048] In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0049] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0050] As described in the background section, some garment processing equipment in the related art is equipped with an automatic lint cleaning mechanism to automatically clean lint from the filter screen. The lint automatically cleaned from the filter screen is usually stored in a lint collection box. When there is a lot of lint in the lint collection box, the lint collection box is removed and the lint is emptied. However, when the drying program is running and the lint collection box has already stored some lint, there may be a situation where a high-speed airflow in the air duct carries some of the lint stored in the lint collection box back into the air duct, which will undoubtedly affect the drying effect of the garment.

[0051] To address the aforementioned problems, the present invention provides a lint filtering device for a garment processing equipment, comprising a filter duct having a filter duct outlet and a filter duct inlet, a filter disposed at the filter duct outlet, a lint collection box disposed at a first end of the filter, and a lint cleaning assembly for scraping lint off the filter. The lint collection box includes a box assembly having a lint inlet and a flip cover pivotally connected to the box assembly for opening and closing the lint inlet. The lint cleaning assembly includes a cleaning section, a top-opening section, and a driving mechanism. The driving mechanism drives the cleaning section and the top-opening section to reciprocate between the first and second ends of the filter to remove lint accumulated on the filter surface. When the assembly moves close to the first end of the filter, the top-opening section opens the flip cover to open the lint inlet, allowing the lint cleaned by the front end of the cleaning section to fall into the box assembly through the lint inlet. When the assembly moves away from the first end of the filter, the flip cover closes the lint inlet.

[0052] In the above solution, by adding a top opening part to the lint cleaning component, when the cleaning part moves to the first end near the filter, the top opening part opens the flip cover at the lint inlet of the lint collection box, allowing the lint cleaned at the front end of the cleaning part to fall into the box assembly of the lint collection box through the lint inlet. When the cleaning part moves to the first end away from the filter, the flip cover closes the lint inlet. This not only achieves the purpose of automatic lint cleaning, but also avoids the situation where the high-speed airflow in the air duct carries some of the lint already stored in the lint collection box back into the air duct, which helps to improve the drying effect.

[0053] The preferred technical solution of the garment processing equipment and its lint filtering device 100 of the present invention will be described below with reference to the accompanying drawings. The garment processing equipment includes a housing, a cylindrical assembly disposed within the housing, and a drying air duct connected to the cylindrical assembly. A drying circulation air path is formed between the drying air duct and the cylindrical assembly for drying the garments inside the cylindrical assembly. The lint filtering device 100 is connected to the drying air duct for filtering out lint from the drying air duct.

[0054] Figure 1 is a structural schematic diagram of a lint filter device 100 of a garment processing apparatus according to an exemplary embodiment of the present invention; Figure 2 is a schematic diagram of an explosion state when the cleaning part and the top opening part of the lint filter device 100 move to a first end close to the filter according to an exemplary embodiment of the present invention; Figure 3 is a schematic diagram of an explosion state when the cleaning part and the top opening part of the lint filter device 100 move to a second end away from the filter according to an exemplary embodiment of the present invention; Figure 4 is a structural schematic diagram of a lint cleaning assembly according to an exemplary embodiment of the present invention; Figure 5 is a structural schematic diagram of a lint collection box according to an exemplary embodiment of the present invention; Figure 6 is an exploded view of the structure in Figure 5.

[0055] As shown in Figures 1 to 3, the lint filtering device 100 includes a filter duct 110 having a filter duct inlet 1111 and a filter duct outlet 1121, a filter 120 disposed in the filter duct 110 along an air path from the filter duct inlet 1111 to the filter duct outlet 1121, a lint collection box 130 disposed at a first end of the filter 120, and a lint cleaning assembly 140 for scraping lint off the filter 120. The lint collection box 130 includes a box assembly having a lint inlet 13111 and a flip cover 132 pivotally connected to the box assembly for opening and closing the lint inlet 13111. The lint removal assembly 140 includes a cleaning part 141, a top opening part 142, and a drive mechanism 143. The drive mechanism 143 drives the cleaning part 141 and the top opening part 142 to reciprocate between the first end and the second end of the filter 120 to remove the lint accumulated on the surface of the filter 120.

[0056] The filter duct inlet 1111 is connected to the outlet of the cylinder assembly via the inlet component 150, and the filter duct outlet 1121 is connected to the inlet of the cylinder assembly via the outlet component 160 to form a circulating air path.

[0057] In some embodiments, the filter 120 has an overall arc-shaped filter surface that covers the air passage between the filter duct inlet 1111 and the filter duct outlet 1121, thereby increasing the filter area and improving the filtration effect. As an example, the filter 120 is curved upwards; in other words, the convex side of the filter 120 faces the filter duct inlet 1111, and the concave side faces the filter duct outlet 1121. Preferably, the filter 120 includes a filter frame and a filter screen disposed on the filter frame. The mesh size of the filter screen is determined according to actual conditions, and this invention does not impose any limitations on it.

[0058] Referring to Figure 2, when the drive mechanism 143 drives the cleaning part 141 and the top opening part 142 to move closer to the first end of the filter 120, the top opening part 142 first opens the flip cover 132 to open the lint inlet 13111, allowing the lint cleaned by the front end of the cleaning part 141 to fall into the housing assembly through the lint inlet 13111. Referring to Figure 3, when the drive mechanism 143 drives the cleaning part 141 and the top opening part 142 to move further away from the first end of the filter 120, the flip cover 132 automatically closes the lint inlet 13111.

[0059] It should be noted that the flip cover 132 is in its normal state when the lint inlet 13111 is closed. Only when automatic lint cleaning is required will the drive mechanism 143 drive the cleaning part 141 and the top opening part 142 to move, thereby allowing the top opening part 142 to open the flip cover 132 and expose the lint inlet 13111. This achieves the purpose of automatic lint cleaning and also avoids the situation where high-speed airflow in the air duct carries some of the lint already stored in the lint collection box 130 back into the air duct, which helps to improve the drying effect.

[0060] In some embodiments, as shown in FIG4, the drive mechanism 143 includes a rotating shaft 1431, a transmission unit 1432, and a drive unit 1433; wherein, the rotating shaft 1431 is connected to the cleaning part 141 and / or the top opening part 142, and the two ends of the transmission unit 1432 are respectively connected to the rotating shaft 1431 and the drive unit 1433, and the drive unit 1433 is, for example, a motor; the drive unit 1433 drives the rotating shaft 1431 to reciprocate between the first end and the second end of the filter 120 through the transmission unit 1432 to drive the cleaning part 141 and the top opening part 142 to move.

[0061] As an example, the top opening portion 142 has a shaft hole connected to the rotating shaft 1431 and a fixing groove for mounting the cleaning portion 141. The shaft hole of the top opening portion 142 passes through the rotating shaft 1431 and is fixed by a snap-fit. The cleaning portion 141 is mounted on the top opening portion 142 via the fixing groove, so that both the cleaning portion 141 and the top opening portion 142 are simultaneously driven by the rotating shaft 1431. Alternatively, the cleaning portion 141 has a shaft hole connected to the rotating shaft 1431 and a fixing groove for mounting the top opening portion 142. The shaft hole of the cleaning portion 141 passes through the rotating shaft 1431 and is fixed by a snap-fit. The top opening portion 142 is mounted on the cleaning portion 141 via the fixing groove, so that both the cleaning portion 141 and the top opening portion 142 are simultaneously driven by the rotating shaft 1431.

[0062] In addition, in some other examples, the drive mechanism 143 may include two rotating shafts 1431 that are respectively connected to the top opening portion 142 and the cleaning portion 141. Both rotating shafts 1431 are connected to the transmission unit 1432, and both the top opening portion 142 and the cleaning portion 141 have shaft holes that are connected to the rotating shafts 1431.

[0063] It should be noted that, as long as the top opening portion 142 and the cleaning portion 141 can be driven by the rotating shaft 1431 to reciprocate between the first and second ends of the filter 120, those skilled in the art can determine the shape of the top opening portion 142 and the cleaning portion 141 and their connection structure with the rotating shaft 1431 based on their specific arrangement within the filter duct 110. Optionally, the cleaning portion 141 can adopt a brush, scraper, or other structure.

[0064] In some embodiments, the transmission unit 1432 includes a driving gear 14321, a driven gear 14322, and a swing arm 14323; wherein the driving gear 14321 is connected to the drive unit 1433, the driven gear 14322 is meshed with the driving gear 14321, and the swing arm 14323 connects the driven gear 14322 and the rotating shaft 1431. In the above scheme, the drive unit 1433 uses gear transmission to drive the rotating shaft 1431 to reciprocate between the first and second ends of the filter 120 to drive the cleaning part 141 and the top opening part 142 to move, which has high transmission efficiency, long service life, and reduces equipment failure rate.

[0065] In some embodiments, referring again to Figures 2 and 3, the filter duct 110 includes an upper duct 111 and a lower duct 112 that are snap-fitted together to hold the filter 120; the bottom wall of the lower duct 112 is constructed as an arc-shaped structure with clearance installation space, the drive unit 1433 is disposed within the clearance installation space, and the transmission unit 1432 is disposed on the outside of the side wall of the lower duct 112; clearance grooves are provided on the side walls of the upper duct 111 and / or the lower duct 112 to allow the swing arm 14323 to swing. This not only facilitates the installation of the filter 120 in the filter duct 110 and improves the stability of the filter 120, but also, by optimizing the structural design of the lint filter device 100, ensures that it fits tightly with other structures inside the garment processing equipment housing, reducing space waste and improving overall neatness.

[0066] The upper air duct 111 and the lower air duct 112 can be connected by fasteners, snap-fit ​​connections, or other connection methods, as long as the filter 120 can be clamped between the upper air duct 111 and the lower air duct 112. Those skilled in the art can determine the connection method between the two based on the specific structure of the upper air duct 111 and the lower air duct 112.

[0067] In some embodiments, two position sensors 1122 are also provided on the side wall of the downdraft duct 112 where the transmission unit 1432 is housed. These sensors sense the position of the swing arm 14323, thereby determining whether the cleaning section 141 and the top opening section 142 have reached the first and second ends of the filter 120 based on the position of the swing arm 14323. The position sensors 1122 can be of a contact type or a non-contact type, such as infrared or laser.

[0068] Furthermore, a protective cover 113 is provided on the side wall of the downdraft duct 112 where the transmission unit 1432 is installed, for protecting the transmission unit 1432 and the position sensor 1122 installed on the side wall.

[0069] In some embodiments, the filter duct inlet 1111 is disposed on the upper duct 111, and the filter duct outlet 1121 is disposed on the back plate of the lower duct 112; wherein, the lint collection box 130 is connected to the portion of the lower duct 112 located above the filter duct outlet 1121. In other words, the first end of the filter 120 is located at the top, and the second end is located at the bottom. Thus, when the drive mechanism 143 drives the cleaning part 141 and the top opening part 142 to move from the second end of the filter 120 towards the first end of the filter 120, the lint cleaned by the front end of the cleaning part 141 can be temporarily stored in the space between the cleaning part 141 and the top opening part 142, preventing the lint from flying in the upper duct 111.

[0070] As an example, there is a certain angle between the cleaning part 141 and the top opening part 142, which is approximately between 70° and 100°, so as to ensure that the space formed between the two can temporarily store the wire debris.

[0071] In some embodiments, as shown in Figures 5 and 6, the lint collection box 130 includes an outer box 131 and an inner box 135 detachably disposed within the outer box 131. The outer box 131 is connected to the filter duct 110 and includes a body 1311 and a cover 1312 that engages with the body 1311. The lint inlet 13111 is disposed on the side wall of the body 1311, opposite to the first end of the filter 120, and is higher than the inner box 135 to allow lint to fall into the inner box 135. As an example, a rear cover 134 may also be detachably disposed on the rear side of the outer box 131 to protect the inner box 135.

[0072] Furthermore, the flip cover 132 is disposed inside the body 1311, and the flip cover 132 includes a shield 1321 pivotally connected to the body 1311 for opening and closing the shavings inlet 13111, a shield 1321 pivotally connected to the body 1311, and a counterweight 1322 connected to the shield 1321.

[0073] Specifically, the baffle plate 1321 is pivotally connected to the body 1311 of the outer box 131 via the pivot shaft 133. When the drive mechanism 143 drives the cleaning part 141 and the top opening part 142 to move to the first end near the filter 120, the top opening part 142 uses the driving force of the drive mechanism 143 to overcome the gravity of the baffle plate 1321 and the counterweight plate 1322, so that the baffle plate 1321 rotates around the pivot shaft 133 to the position of exposing the lint inlet 13111. The lint that has been cleaned up and is located at the front end of the cleaning part 141 then falls into the inner box 135 for storage through the lint inlet 13111.

[0074] When the drive mechanism 143 drives the cleaning part 141 and the top opening part 142 to move to the first end away from the filter 120, it is equivalent to removing the force applied to the baffle plate 1321. Under the combined action of its own weight and the weight of the counterweight plate 1322, the baffle plate 1321 automatically rotates around the pivot axis 133 to the position of closing the lint inlet 13111. Moreover, when the drying program is running, under the action of the weight of the counterweight plate 1322, the drying gas flowing through the filter air duct 110 cannot blow open the baffle plate 1321, preventing the lint stored in the inner box 135 from being brought back into the filter air duct 110 and affecting the filtration effect.

[0075] As an example, the counterweight plate 1322 can also be regarded as the top cover of the inner box 135. When the baffle plate 1321 and the counterweight plate 1322 automatically rotate to the position of closing the wire chip inlet 13111, the counterweight plate 1322 covers the open inner box 135.

[0076] In some embodiments, a handle 13121 is provided on the side of the cover 1312 facing away from the body 1311. This allows the cover 1312 to be opened by the handle 13121 when a certain amount of lint is stored in the inner box 135 of the box assembly. The flip cover 132 can then be manually flipped over to remove the inner box 135 from the outer box 131, the lint can be emptied, and the inner box 135 can be placed back into the outer box 131. This avoids the need for complete disassembly of the lint collection box 130, facilitating user operation and improving the user experience.

[0077] Preferably, the inner box 135 is removably installed in the outer box 131, making it more convenient for users to operate.

[0078] Furthermore, the baffle plate 1321 and the counterweight plate 1322 have a preset angle, which is approximately between 80° and 100°. Preferably, the preset angle between the baffle plate 1321 and the counterweight plate 1322 is 90°. Moreover, the free end of the counterweight plate 1322 is in contact with the side wall of the body 1311 opposite to the lint inlet 13111. This allows the contact force between the counterweight plate 1322 and the body 1311 of the outer casing to overcome the thrust of the drying gas in the filter duct 110 on the baffle plate 1321. It should be noted that the side wall of the body 1311 opposite to the lint inlet 13111 should be provided with a relief surface that avoids the free end of the counterweight plate 1322 when the baffle plate 1321 and the counterweight plate 1322 rotate. The convex side of this relief surface faces the outside of the casing assembly.

[0079] In some embodiments, the counterweight plate 1322 is provided with a guide opening 13221, and the cover 1312 is provided with a guide post 13122 passing through the guide opening 13221 on the side facing the main body 1311. When the flip cover 132 pivots relative to the main body 1311, the guide post 13122 guides the movement direction of the counterweight plate 1322, preventing the counterweight plate 1322 from deviating during the movement, causing the counterweight plate 1322 to return to its original position with sluggishness and lack of smoothness, which would prevent the shielding plate 1321 from closing the lint inlet 13111.

[0080] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
