Description

Technical Field

[0001] The present invention belongs to the field of clothes dryer equipment, and in particular, relates to a lint filter and a clothes processing device. Background Art

[0002] A clothes dryer is a cleaning household appliance that uses electric heating to evaporate the water in washed clothes instantly. In the winter in the north and the "return of the south wind" in the south, clothes are difficult to dry, so a clothes dryer is particularly needed to dry clothes.

[0003] During the rotation of the dryer drum or the operation of the dryer, dry hot air is input into the drum from the air inlet, the hot air contacts the wet clothes and takes away moisture, and the wet hot air is discharged through the exhaust port, and the hot air circulates continuously in this way to achieve the effect of drying clothes. During the operation of the dryer, the rotation of the drum and the tumbling of the clothes will generate a small amount of clothing lint in the drum, and move with the air flow. When the lint enters the air duct, it will cause secondary pollution to the clothes. In order to prevent lint from entering the air duct, the hot air circulation will pass through a lint filter. Existing dryer lint filters are usually sheet-shaped, and a filter net is arranged between the sheet frames, which is inserted vertically or obliquely into the air duct. The filtration area of ​​the sheet-shaped lint filter is small. At the same time, due to the blockage of lint or the unevenness of the mesh of this single-layer filter net, it is easy to cause a decrease in filtration efficiency, and the filter net with a single filtration efficiency is limited in efficiency for lint filtration, resulting in unsatisfactory filtration effect.

[0004] This single-layer filter has disadvantages in filtering the air flow from outside to inside when the dryer is not in operation and is located in a dusty working environment. It also has great defects in blocking the internal and external environments of the dryer. In addition, the existing filter and the components of the lint filter are usually integrated, which makes it very inconvenient to clean or replace the filter. The entire filter needs to be cleaned every time it is cleaned. This extensive maintenance method that does not distinguish the filtering characteristics of the filter layer also increases the cleaning burden of the user and is not conducive to the timely cleaning of the filter device. At the same time, this integrated setting easily forms a cleaning dead corner at the connection between the filter and the components. The lint in this part cannot be effectively cleaned, and still causes pollution to the air flow system inside the dryer. The existing connection structure between the lint filter and the dryer body is also not conducive to the disassembly and maintenance of the lint filter, and corresponding modifications are required.

[0005] In view of this, the present invention is proposed. Summary of the invention

[0050] like Figures 1 to 5As shown, the present invention discloses a lint filter and a clothing treatment device, comprising a first filter assembly 1 and a second filter assembly 2 which are detachably connected via a connection device 3, wherein the second filter assembly 2 comprises multiple filter layers to achieve multiple filtering of lint. The present invention adopts a multiple filtering method, and utilizes filter layers with different filtering efficiencies to filter lint in the clothing treatment device, thereby enhancing the efficiency and reliability of lint filtering, and effectively achieving the filtering effect when air flows between the internal and external environments of the dryer and the separation of the internal and external environments, while facilitating users to perform separate maintenance on different filter layers, while reducing the difficulty and cost of maintenance and enhancing the pertinence and effectiveness of cleaning. The present invention optimizes the installation structure of the lint filter, making it easier for users to disassemble and install, and more conducive to timely and effective cleaning of the lint filter.

[0051] Example 1

[0052] like Figures 1 to 5 As shown, this embodiment discloses a lint filter for a clothes processing device. The clothes processing device includes a clothes dryer or a washer-dryer. In order to prevent lint from circulating in the drying system, causing air duct blockage, clothes contamination or other malfunctions, the clothes processing device is provided with a lint filter. Figure 4 and Figure 5 As shown, in this embodiment, an opening is provided on the front support panel 01 of the clothes dryer, a lint filtering device is provided in the opening, and a filtering assembly is provided on the lint filtering device to provide lint filtering for the clothes dryer.

[0053] like Figure 1 As shown, the lint filter of this embodiment includes a first filter component 1 and a second filter component 2 which are detachably connected via a connecting device 3, wherein the second filter component 2 includes multiple filter layers to achieve multiple filtering of lint. Specifically, as shown in the figure, the second filter component 2 includes two filter layers with different lint filtering efficiencies—a second filter layer 201 and a third filter layer 203.

[0054] like Figure 1 As shown in , the first filter assembly 1 includes: a frame structure 101 of the first filter assembly connected to the connecting device 3, and a first filter layer 102. The first filter layer 102 is disposed in the frame structure 101 of the first filter assembly, and its periphery is connected to the frame of the frame structure. In this embodiment, support ribs 103 of the first filter assembly connected to the connecting device 3 are also disposed in the frame structure 101 of the first filter assembly. The number of support ribs 103 of the first filter assembly is plural and distributed in the same plane. Figure 1As shown, these support ribs are cross-distributed and form a grid structure, and the first filter layer 102 with a lint filtering function is covered on the support ribs 103 of the first filter assembly (the first filter layer 102 in this embodiment is a filter mesh), forming the main filter component of the first filter assembly 1. This grid structure of this embodiment is more conducive to maintaining the structural stability and strength of the first filter assembly, and ensures the requirements for multiple disassembly and installation of the filter assembly.

[0055] like Figure 1 As shown, the second filter component 2 includes two filter layers, namely a second filter layer 201 and a third filter layer 203 which are detachably connected to the first filter component 1 via a connecting device 3 respectively.

[0056] The third filter layer 203 in this embodiment includes a plurality of third filter layer support ribs 204 and a filter screen 205. Similar to the first filter assembly, the third filter layer support ribs 204 are cross-distributed and form a grid structure of the third filter layer, and the filter screen 205 covers the third filter layer support ribs 204 to form the third filter layer 201.

[0057] like Figure 1 As shown, a second filter layer 201 is arranged between the first filter layer 102 and the third filter layer 203. The filtering efficiency of the second filter layer 201 is different from the filtering efficiency of the first filter layer 102 and the third filter layer 203. Specifically, in this embodiment, the filtering efficiency of the first and third filter layers is lower than that of the second filter layer. The filter medium used is a filter mesh as the filter medium for the first and third filter layers, while the second filter layer is a sponge. Compared with the filter mesh, the sponge has a certain thickness, and the large number of holes inside not only ensures the permeability of the gas, but also ensures the requirement of filtering finer wire scraps. Compared with the previous device that uses a single filter medium for wire scrap filtering, this design improves the wire scrap filtering effect.

[0058] At the same time, this embodiment uses three layers of filtration, and the second filter layer 201 with the highest filtration efficiency is placed between the first filter layer 102 and the third filter layer 203. The air in both directions of the dryer and the external environment can be preliminarily coarsely filtered through the first filter layer or the third filter layer for coarse wire scraps. For wire scraps in the dryer, such coarse wire scraps are often the main factor causing the pipe blockage of the dryer, and the proportion of wire scraps in this part is the largest. Therefore, after the coarse filtration of these two filter layers, the filtration pressure of the second filter layer can be effectively reduced, the effective filtration time of the second filter layer is greatly extended, the frequency of maintenance or replacement of the second filter layer is reduced, and the maintenance difficulty and cost are reduced. At the same time, such a setting allows users to perform separate maintenance on different filter layers according to the wire scrap siltation of different filter layers, which enhances the pertinence and effectiveness of cleaning. In addition, the first and third filter layers are both arranged on the outer layer of the wire scrap filter device, and can be easily cleaned through a dust removal device or a flushing device even without disassembling the filter layer, which is conducive to the user's timely cleaning of the wire scrap filter device and reduces the number of times the wire scrap filter device is disassembled.

[0059] This method of triple filtration in two directions effectively achieves the filtering effect when air flows between the internal and external environments of the dryer and the separation of the internal and external environments, reducing the possibility of air pollution inside the dryer.

[0060] In order to realize the above-mentioned multiple filtering functions of the lint filtering while ensuring the reliable connection and convenient disassembly between the filter components, the present invention uses a connecting device 3 to connect the above-mentioned filter components.

[0061] like Figure 1 and Figure 2 As shown, the connecting device 3 of this embodiment includes a mounting portion 301 and a connecting portion connected to each other, the mounting portion 301 is connected to the first filter component or the second filter component, and the connecting portion is detachably connected to the corresponding second filter component or the first filter component, thereby realizing a detachable connection between the first filter component and the second filter component.

[0062] like Figure 2 As shown, the connecting portion includes a snap-fit ​​portion 303 connected to the mounting portion 301, and the snap-fit ​​portion 303 is snap-fitted with the third filter layer 203 of the second filter component 2; the mounting portion 301 is connected to the first filter component 1; and a detachable connection between the third filter layer 203 and the first filter component 1 is achieved.

[0063] like Figures 1 to 3 As shown, the clamping portion 203 includes a clamping claw, which is clamped and connected to the support rib 204 of the third filter layer. Figure 2 and 3As shown, the position where the clamping claw is clamped with the support ribs 204 of the third filter layer is located at the cross-connection of the support ribs 204 of the third filter layer of the grid structure of the third filter layer 203. Each of the clamping claws has a plurality of claw hooks for clamping, and the number of the claw hooks is the same as the total number of the cross-connected support ribs 204 of the third filter layer at the clamping position. The support ribs 204 of the third filter layer are inserted into and block the gaps between the adjacent claw hooks of the clamping claw, so as to realize the clamping connection between the clamping claw and the support ribs 204 of the third filter layer. Specifically, as shown in FIG. Figure 3 As shown, the number of support ribs at the cross-connections of the support ribs 204 of the third filter layer of the grid structure of the third filter layer 203 in this embodiment is 4, so the number of claw hooks of the claw is also 4, which are engaged with the support ribs to achieve a reliable snap-on connection between the connecting device 3 and the third filter layer 203.

[0064] like Figure 1 and Figure 2 As shown, the connection part of the connection device 3 also includes a plug-in part 302 that connects the mounting part 301 and the clamping part 303. The second filter layer 201 is provided with a plug-in hole 202 that plugs with the plug-in part 302; the plug-in hole 202 is located in the second filter layer 201 and penetrates the thickness direction of the second filter layer 201. The plug-in part 302 is inserted into and passes through the plug-in hole 202 to achieve plug-in connection between the first filter component 1 and the second filter layer 201. Figure 2 As shown, the clamping portion 303 and the plug-in portion 302 of this embodiment are integrally arranged. In other embodiments, the connection portion 303 and the plug-in portion 302 can also be detachably connected by other means such as threading or sleeve connection to achieve the connection between the plug-in portion and the clamping portion.

[0065] The plug-in connection part of the connection device of the present invention makes full use of the second filter layer having a certain thickness and the reliable clamping characteristics of the first filter assembly and the third filter layer, and can conveniently realize the position limiting of the second filter layer by only using the plug-in cooperation of the plug-in hole and the plug-in connection part, so that the position limiting connection structure of the second filter layer is simple, and the installation and removal of the second filter layer are convenient.

[0066] like Figure 1 and 2 As shown, the mounting portion 301 of the connecting device 3 of this embodiment is fixedly connected to the first filter assembly 1, thereby achieving a fixed connection between the first filter assembly 1 and the connecting device 3. Further, as shown in the figure, the mounting portion 301 is integrally arranged with the supporting rib 103 of the first filter assembly.

[0067] In other embodiments, the mounting portion of the connecting device and the first filter assembly are connected by mounting claws that are arranged on the mounting portion and engage with the first filter assembly, so that the first filter assembly and the connecting device are connected by the mounting claws, thereby realizing a detachable connection between the connecting device and the first filter assembly. The mounting claw has a similar structure to the connecting portion, and the mounting claw is engaged with the support ribs of the first filter assembly, and the position where the mounting claw engages with the support ribs of the first filter assembly is located at the cross-connection of the support ribs of the grid structure of the first filter assembly. This configuration allows the connecting device to exist independently of the filter assembly, and the connecting device can be connected from the direction of the first filter assembly or in the direction of the third filter layer, making the connection method of the filter assembly more flexible.

[0068] Example 2

[0069] This embodiment is a structural supplement to the lint filter of Embodiment 1, and discloses a connection device between the lint filter and a clothes processing device.

[0070] The clothes processing device in this embodiment is a clothes dryer or a washer-dryer, and its front support panel is made of a metal material that can be attracted by a magnet. Figure 1 As shown, the first filter assembly 1 of this embodiment includes a magnetic device fixing part 104 of the first filter assembly, and a magnetic device 105 of the first filter assembly matched therewith. The magnetic device 105 of the first filter assembly is detachably connected to the first filter assembly in the magnetic device fixing part 104 of the first filter assembly, and the first filter assembly 1 is connected to the dryer or the washer-dryer by the magnetic device 105 of the first filter assembly and the front support panel of the dryer or the washer-dryer. At the same time, since the second filter assembly of the lint filter device is also connected to the first filter assembly through the connecting device, the entire lint filter device is fixed relative to the clothing processing device by the magnetic device and the front support panel of the dryer or the washer-dryer. This fixing method is more convenient for the installation and removal of the lint filter device from the clothing processing device, and is convenient for the user to inspect and clean the lint filter device.

[0071] Example 3

[0072] This embodiment is a further supplement to the structure of the lint filter of Embodiments 1 and 2. Figure 1 As shown, the lint filter of this embodiment also includes a handle 4, which is fixedly connected to the first filter assembly 1 and detachably connected to the front support panel of the dryer or the washer-dryer, thereby realizing the detachable connection between the lint filter and the dryer or the washer-dryer.

[0073] like Figure 1As shown, the handle 4 is designed as a whole with the first filter assembly 1, and is provided with a magnetic device 401 of the handle, and the function is similar to that of the magnetic device of Example 2. The handle 4 is attracted to the front support panel of the dryer or the washer-dryer through the magnetic device 401 of the handle, so as to realize the detachable connection between the first filter assembly and the dryer or the washer-dryer. The magnetic device 401 of the handle in this embodiment can be fixed on the handle or can be as shown in FIG. Figure 1 The handle shown and similar to the magnetic device of Example 2 is detachably connected.

[0074] In other embodiments, the handle may also be connected to a second filter assembly, which will not be described in detail here.

[0075] The handle and the filter assembly are integrated, which makes it easy to remove the filter assembly from a complex structure, making it more convenient for users to operate, disassemble and install. Cleaning the lint filter is no longer a burden for users, and is more conducive to timely and effective cleaning of the lint filter.

[0076] Example 4

[0077] This embodiment is a supplement to the lint filter of embodiment 1. The difference between this embodiment and embodiment 1 is that the support ribs in the frame structure of the first filter assembly in this embodiment do not cross each other, and multiple parallel support ribs are arranged in a vertical direction, which can be conveniently matched with the flushing device of the lint filter, reducing the lint blocking caused by the horizontal support ribs and reducing the sanitary dead corners when cleaning the first filter layer.

[0078] Example 5

[0079] This embodiment is a supplement to the lint filter of Embodiment 1 and Embodiment 4. The difference between this embodiment and Embodiment 1 and Embodiment 4 is that there are no supporting ribs in the frame structure of the first filter assembly in this embodiment, and the connecting device is fixed to the frame, or the filter screen is rigid, and the connecting device is directly connected to the filter screen to achieve the connection between the first filter assembly and the second filter assembly.

[0080] Example 6
