Description

Technical Field

[0001] This utility model relates to the technical field of clothing processing equipment, specifically providing a dandruff removal device and a clothing processing equipment with a drying function. Background Technology

[0002] In the design of garment processing equipment with drying functions, filters are usually installed inside the drying duct to effectively filter impurities such as lint and fibers carried by the airflow during the drying process. However, after long-term use and the accumulation of a certain amount of impurities, these filters often require manual cleaning or replacement due to their limited self-cleaning ability. This undoubtedly increases the user's maintenance costs and operational complexity.

[0003] Although lint removers with a single-helix structure are available on the market, designed to automatically remove impurities from filters mechanically, this single-helix structure has gradually revealed some significant shortcomings in practical applications. The primary problem lies in its limited cleaning efficiency. Due to the relatively simple working principle of the single-helix structure, its ability to remove large amounts of lint and impurities is limited, making it difficult to meet the growing demand for fast and efficient cleaning. Secondly, the single-helix structure is prone to generating significant eddies and turbulence during operation. This not only affects the flow field stability of the drying duct but may also adversely impact the overall performance of the garment processing equipment, such as reducing drying efficiency and increasing energy consumption. Utility Model Content

[0008] Compared to a single-helix structure, this invention uses a double-helix or multi-helix structure as the working component of the lint removal device, which has the advantage of higher lint removal efficiency.

[0013] In some feasible embodiments of the chip removal device described above, the drive mechanism includes a motor and a transmission assembly, wherein the motor is driven to each of the screws via the transmission assembly.

[0014] In some feasible embodiments of the chip removal device described above, the chip removal device further includes a collection box, and the collection box and the drive mechanism are respectively disposed at both ends of the filter screen.

[0030] Please see Figures 1 to 3This invention provides a lint removal device, which is installed in the drying duct 5 of a clothing processing device such as a dryer, to filter lint from the airflow during the drying process. The lint removal device includes a filter screen 1 and multiple screws 2, all of which are located on the same side of the filter screen 1 and their axes are parallel to each other.

[0031] Specifically, there are two or more screws 2, all parallel to each other and located on the same side of the filter screen 1. When the chip removal device is installed inside the drying air duct 5, the screws 2 are arranged in parallel on the air inlet side of the filter screen 1. This layout design facilitates coordinated operation and improves chip removal efficiency. The number of screws 2 should not be excessive, generally 2 to 4. The specific number of screws 2 can be selected according to actual needs. For example, there can be two screws 2, arranged parallel to each other on the air inlet side of the filter screen 1.

[0032] like Figure 1 or Figure 3 As shown, each screw 2 includes a rotating shaft 21 and a spiral blade 22 disposed on the rotating shaft 21. The spiral blade 22 abuts against at least a portion of the filter screen 1, and the spiral blades 22 of adjacent screws 2 move in opposite directions.

[0033] in, Figure 3 This is a cross-sectional view obtained by cutting the chip removal device along an axis perpendicular to the rotation axis 21. The spiral blades 22 partially abut against the filter screen 1 and continuously scrape away debris from the filter screen 1 during rotation. This multi-screw assembly is more efficient than traditional direct scraping cleaning structures, maintaining the filter screen 1 clean and unobstructed in real time, reducing the frequency of manual cleaning, and thus lowering maintenance costs and time for users. The spiral blades 22 of adjacent screws 2 move in opposite directions. This design helps create a cross-scraping effect on the filter screen 1, further improving chip removal efficiency. Simultaneously, it prevents localized debris accumulation on the filter screen 1, extending its service life.

[0034] In this embodiment, the spiral blades 22 of adjacent screws 2 move in opposite directions. This can be either the rotation direction of the rotating shaft 21 is the same but the spiral blades 22 rotate in opposite directions, or the spiral blades 22 rotate in the same direction but the rotation direction of the rotating shaft 21 is opposite. By moving the spiral blades 22 in opposite directions, lint can be more effectively dispersed and transported, preventing it from accumulating in a certain area and causing blockages. For ease of explanation, the following description uses two screws 2 as an example:

[0035] In one implementation, such as Figures 1 to 3As shown, the spiral blades 22 of the two screws 2 rotate in opposite directions. The chip removal device also includes a drive mechanism 3, which is drivenly connected to the two screws 2 respectively. The drive mechanism 3 includes a motor 31 and a transmission assembly. The transmission assembly includes a driving gear 32 and a driven gear 33 that is drivenly connected to the driving gear 32. The driving gear 32 is connected to the output shaft of the motor 31, and the rotation shaft 21 of each screw 2 is connected to a driven gear 33.

[0036] During operation, the motor 31 drives the drive gear 32 to rotate, which in turn drives the two driven gears 33 to rotate. Each driven gear 33 is connected to the rotating shaft 21 of the corresponding screw 2, thereby driving the rotating shaft 21 and the spiral blades 22 on the rotating shaft 21 to rotate. Under the driving action of the motor 31 with a single power source, multiple screws 2 are driven to rotate simultaneously in the same direction. At this time, when the spiral blades 22 of two adjacent screws 2 rotate in opposite directions, they will generate opposite thrusts during operation. The wire chips are collected on both sides, preventing the two screws 2 from affecting the collection of wire chips. This ensures that the material or debris can be transported or removed more effectively under the push of the screws 2, thereby improving the chip removal efficiency.

[0037] Furthermore, since the driven gears 33 are of the same size, the power generated by the motor 31 can be evenly distributed to each driven gear 33, thereby driving each screw 2 to rotate synchronously. Because the transmission relationship between all driven gears 33 and the driving gear 32 is consistent, it can be ensured that all screws 2 rotate at the same speed or in the same direction according to a preset speed ratio. The synchronous rotation of the two screws 2 through the same drive source (motor 31) and gear transmission helps ensure their coordination and consistency during the chip removal process, thereby improving chip removal efficiency.

[0038] Alternatively, two motors 31 can be set, each connected to a screw 2. The two motors 31 move in the same direction, which can also make the spiral blades 22 of adjacent screws 2 move in opposite directions.

[0039] In another embodiment, the spiral blades 22 of the two screws 2 rotate in the same direction. The drive mechanism 3 includes two motors 31 and two transmission components. The two motors 31 are respectively driven by one screw 2 through the transmission components. The transmission components include a driving gear 32 and a driven gear 33 that is driven by the driving gear 32. The driving gear 32 is connected to the output shaft of the corresponding motor 31. The rotation shaft 21 of each screw 2 is connected to a driven gear 33. The two motors 31 rotate in opposite directions, thereby achieving opposite directions of movement of the two spiral blades 22. Alternatively, only one drive motor 31 can be provided, combined with the transmission components, to drive the two screws 2.

[0040] like Figure 3As shown, the filter screen 1 has a filter surface that is adapted to each screw 2. This is beneficial to increase the contact area between the spiral blades 22 of the screw 2 and the filter screen 1 during rotation. That is, the spiral blades 22 can contact the filter surface more effectively during rotation, thereby more effectively scraping away impurities such as lint and lint captured by the filter surface, which is beneficial to improving the lint removal efficiency.

[0041] Furthermore, the filter surface is a semi-enclosed arc-shaped filter surface, with multiple arc-shaped filter surfaces interconnected to form a continuous structure with a wavy cross-section. The wavy filter surface increases the surface area of ​​the filter screen 1 compared to a flat filter screen; a larger filtration area means more impurities can be captured, thus improving chip removal efficiency. When the spiral blades 22 perform their cleaning task, sweeping away impurities from the filter surface, the wavy filter screen 1 also acts as a temporary impurity collector, effectively accommodating the impurities cleaned by the spiral blades 22. Under the powerful thrust generated by the rotation of the spiral blades 22, these impurities are smoothly pushed and collected into the collection box 4, making the entire chip removal process both efficient and smooth.

[0042] In this embodiment, as Figure 1 and Figure 2 As shown, the chip removal device also includes a collection box 4, and the collection box 4 and the drive mechanism 3 are respectively disposed at both ends of the filter screen 1.

[0043] The collection box 4 is located at the end of the filter screen 1 furthest from the drive mechanism 3. It is mainly used to collect and hold the impurities removed from the filter screen 1 by the spiral blades 22. These impurities may include lint, lint, dust, etc., that fall off the clothes during the drying process. This not only prevents these impurities from clogging the filter screen 1 and affecting the efficiency of hot air circulation, but also prevents them from re-entering the drying air duct 5, thereby avoiding secondary pollution of the clothes. This ensures that the clothes are cleaner and tidier after drying.

[0044] Furthermore, the collection box 4 has a storage opening on the side near the screw 2, and the edge of the storage opening is bent inward to form a scraper that can contact the spiral blade 22 (not shown in the figure).

[0045] By designing the contact between the scraper and the spiral blade 22, when the spiral blade 22 rotates on the rotating shaft 21, it can not only push the impurities on the surface of the filter screen 1 toward the collection port, but also further clean the stubborn impurities attached to the end of the spiral blade 22 in the conveying direction through the friction and scraping action of the scraper, thus enhancing the lint removal effect and ensuring that the removed impurities can be smoothly recycled into the collection box 4.

[0046] This utility model also provides a clothing processing device with a drying function, which includes the dandruff removal device in any of the foregoing technical solutions.

[0047] Specifically, such as Figure 4 As shown, the garment processing equipment also includes a cabinet, inside which a drying air duct 5 is formed, and a lint remover is installed inside the drying air duct 5.

[0048] During the clothes drying process in the clothing processing equipment, a high-temperature airflow generated by the heater is delivered to the inner drum. This high-temperature airflow not only penetrates the clothes, effectively removing moisture, but also carries some impurities along the drying duct 5 until it passes through the filter screen 1 inside the drying duct 5. The filter screen 1, with its excellent filtration performance, successfully intercepts and captures the impurities carried in the airflow. At this point, the spiral blades 22 on the screws 2 begin to play their unique role. During rotation, the spiral blades 22 on both screws 2 work together to continuously scrape away the impurities accumulated on the filter screen 1. Simultaneously, thanks to the thrust generated by the rotation of the spiral blades 22, these scraped impurities are smoothly pushed towards the collection box 4 until they finally reach the collection box 4. This not only achieves efficient filtration of impurities but also ensures that impurities can be collected and recovered. Compared with traditional methods, this clothing processing equipment significantly improves lint removal efficiency, reduces potential damage to the drying duct 5 and the equipment caused by impurities, extends the service life of the equipment, and provides users with a more convenient and efficient clothes drying experience. In addition, the airflow in the drying duct 5 is redistributed and guided by two independent helical blades 22, which helps to offset some of the eddies and resistance, and can reduce the phenomenon of large eddies and turbulence caused by the use of a single helical structure, thereby reducing the impact on the existing flow field.

[0049] Furthermore, the filter 1 is detachably installed in the drying air duct 5, meaning the filter 1 is detachably connected to the housing. This detachable design allows users to easily remove and replace the filter 1, effectively preventing clogging caused by the accumulation of stubborn impurities over time. It also solves the performance degradation problem that may result from long-term wear. Regular cleaning and maintenance not only ensure the continuous and efficient operation of the filter 1 but also significantly extend its lifespan and that of the entire drying equipment.

[0050] In addition, the collection box 4 is also detachably connected to the main body. This detachable design allows users to easily remove the collection box 4 from the garment processing unit for thorough cleaning. This prevents bacteria growth and odor problems caused by impurities remaining in the collection box 4 for extended periods, ensuring the hygiene and cleanliness of the drying equipment.

[0051] Compared to a single-helix structure, this invention uses a double-helix or multi-helix structure as the working component of the lint removal device, which has the advantage of higher lint removal efficiency. Furthermore, two independent helical blades 22 are used between two adjacent screws 2 to redistribute and guide the airflow, which helps to offset some of the eddies and resistance. This reduces the large eddies and turbulence generated by using a single-helix structure, thereby reducing the impact on the existing flow field.

[0052] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
