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 drum of the dryer 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 the 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. The existing lint filter of the dryer is usually in the form of a sheet, and a filter net is arranged between the sheet frames, which is inserted vertically or obliquely into the air duct. The filtering area of ​​the sheet-shaped lint filter is small. At the same time, due to the blockage of lint or the unevenness of the grid, this single-layer filter net is easy to cause a decrease in filtering efficiency, and the filter net with a single filtering efficiency is limited in efficiency for filtering lint, resulting in an unsatisfactory filtering effect. Therefore, it is necessary to design a lint filter device that can provide multiple filtering.

[0004] Providing multiple lint filters requires a special connection device for the filter components. The connection device must not only meet the connection requirements between the filter components, so that different filter components can be securely connected when in use, but also not affect the filtration efficiency. In addition, when the filter components need to be cleaned, the connection device must also be able to meet the requirements of frequent disassembly and installation, so that users can easily disassemble the lint filter and clean different filter components separately.

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

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

[0029] A lint filter and clothing processing device of the present invention adopts a multiple filtering method, using filter layers with different filtering efficiencies to filter lint in a dryer or a washer-dryer, and different filter components are detachably fixedly connected through a connecting device.

[0030] The connection device of the present invention enables a detachable connection between the first filter assembly and the second filter assembly, so that the two filter assemblies can be easily disassembled, and different filter assemblies can be cleaned and maintained separately. The connection between the connection part of the connection device and the filter assembly is connected by a snap-fit ​​method, which not only meets the requirement of a secure connection, but also makes the installation and removal of the filter assembly easier.

[0032] The mounting portion of the connection device of the present invention can be fixedly connected to the first filter assembly or detachably connected. When the first filter assembly is also detachably connected to the first filter assembly, the connection device becomes a separate component independent of the filter assembly. In this way, the connection device can be used universally on different filter assemblies, and the fixing and connecting positions can be flexibly selected according to the specific characteristics of different filter assemblies, making the installation and maintenance of the connection device more flexible and convenient.

[0033] When the mounting portion and the first filter assembly are detachably connected, a snap-on structure can be used to achieve a fixed connection between the two, which is similar to the connection with the bracket, and is not only firmly connected but also more convenient to disassemble.

DETAILED DESCRIPTION

[0045] In order to make the purpose, 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 in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0047] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0048] like Figures 1 to 5As shown, the present invention discloses a lint filter and a clothing processing device, comprising: a first filter assembly 1 and a second filter assembly 2 with a lint filtering function, wherein the first filter assembly 1 and the second filter assembly 2 are detachably and fixedly connected to each other through a connecting device 3. The present invention realizes the detachable connection of multiple lint filter assemblies through a connecting device, and the connecting device has a simple structure and flexible installation, which is more convenient for users to disassemble and install, and facilitates users to perform separate maintenance on the filter layers, which is more conducive to timely and effective cleaning of the lint filter; at the same time, the connecting device is firmly connected, meeting the connection requirements of the filter using multiple filtration, so that the lint filter can use filter layers with different filtration efficiencies to filter lint in the clothing processing device, thereby enhancing the efficiency and reliability of lint filtering.

[0049] Example 1

[0050] like Figures 1 to 5 As shown, this embodiment discloses a lint filter for a clothes processing device, including a first filter assembly 1 and a second filter assembly 2 with lint filtering functions. In order to ensure reliable connection and convenient disassembly between the filter assemblies when performing multiple filtering functions of lint filtering, the present invention uses a connecting device to detachably and fixedly connect the first filter assembly and the second filter assembly. 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.

[0051] 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.

[0052] like Figure 1 As shown, the lint filter of this embodiment includes a first filter component 1 detachably connected by a connecting device 3, and a second filter component 2, wherein the second filter component 2 includes a second filter layer 201 having a different filtering efficiency from the first filter component 1 and a bracket 203 for connecting and fixing.

[0053] like Figure 2 As shown, the connection portion includes a clamping portion 303 connected to the mounting portion 301. The clamping portion 303 is clamped and matched with the bracket 203, and the mounting portion 301 is connected to the first filter assembly 1, so as to realize a detachable connection between the bracket 203 and the first filter assembly 1. The second filter layer 201 is located between the first filter assembly 1 and the bracket 203.

[0054] like Figures 1 to 3 As shown, the clamping portion 303 of this embodiment includes a clamping claw, and the bracket 203 has a plurality of bracket support ribs 204, which are cross-distributed and form a grid structure of the bracket. The clamping claw is clamped and connected with the bracket support ribs 204. Figure 2 and 3 As shown, the position where the clamping claw is clamped with the support rib 204 is located at the cross-connection of the support rib 204 of the grid structure of the support 203. Each of the clamping claws has a plurality of claw hooks 304 for clamping, and the number of the claw hooks 304 is the same as the total number of the cross-connected support ribs 204 at the clamping position. The support rib 204 is inserted into and blocks the gap between the adjacent claw hooks of the clamping claw, so as to realize the clamping connection between the clamping claw and the support rib 204.

[0055] Specific as Figure 3 As shown, the number of support ribs at the cross-connection of the support ribs 204 of the grid structure of the bracket 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 bracket 203.

[0056] 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.

[0057] The filtration efficiency of the second filter layer 201 is different from the filtration efficiency of the first filter layer 102 and the bracket 203. Specifically, in this embodiment, the filtration efficiency of the first filter component is lower than that of the second filter layer: the first filter component uses a filter mesh as a filter medium, while the second filter layer uses a sponge as a filter medium. 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] 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 bracket, 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.

[0059] 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, so as to realize the fixed connection between the first filter assembly 1 and the connecting device 3. Alternatively, when the first filter assembly is fixedly connected to the connecting device, the mounting portion is integrally arranged with the first filter assembly. Further, as shown in the figure, the mounting portion 301 is integrally arranged with the supporting rib 103 of the first filter assembly.

[0060] In other embodiments, the mounting portion of the connecting device and the first filter component are connected by providing a mounting claw on the mounting portion that is engaged with the first filter component, so that the first filter component and the connecting device are engaged by the mounting claw, thereby achieving a detachable connection between the connecting device and the first filter component.

[0061] like Figure 1 As shown in , in these embodiments, the first filter component 1 includes: a frame structure 101 of the first filter component connected to the connecting device 3, and a first filter layer 102. The first filter layer 102 is arranged in the frame structure 101 of the first filter component, and its periphery is connected to the frame of the frame structure. In this embodiment, support ribs 103 of the first filter component connected to the connecting device 3 are also arranged in the frame structure 101 of the first filter component. The number of support ribs 103 of the first filter component is plural and distributed in the same plane. Figure 1 As 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.

[0062] The structure of the mounting claw in this embodiment is similar to that of the connecting portion, and the mounting claw is engaged with the support rib 103 of the first filter assembly, and the position where the mounting claw is engaged with the support rib 103 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 from the direction of the bracket, making the connection method of the filter assembly more flexible. The connecting device uses detachable connections at both ends, so that the connecting device can be used on different filter assemblies, and the fixing and connecting positions can be flexibly selected according to the specific characteristics of different filter assemblies, making the installation and maintenance of the connecting device more flexible and convenient.

[0063] Example 2

[0064] 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.

[0065] 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.

[0066] Example 3

[0067] 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.

[0068] 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.

[0069] In other embodiments, the handle may also be connected to a second filter assembly, which will not be described in detail here.

[0070] 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.

[0071] Example 4

[0072] 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.

[0073] Example 5

[0074] 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.

[0075] Example 6

[0076] This embodiment is a supplement to the above embodiment. In this embodiment, a filter screen is arranged on the bracket 203 to form a third filter screen, thereby realizing triple filtering of the lint filter. The third filter layer in this embodiment includes a plurality of bracket support ribs and a filter screen. The filter screen covers the bracket support ribs to form the third filter layer.

[0077] 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. 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.

[0078] 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.

[0080] This embodiment discloses a clothes processing device, which uses the lint filter as described in any of the above embodiments. The clothes processing device includes a dryer or a washer-dryer.

[0081] The integrated washer-dryer of this embodiment includes a washing device and a drying device. The washing device includes a washing tub, and the washing tub includes an outer tub and an inner tub. The drying device includes a heating duct, a drying fan and a condenser. One side of the heating duct is connected to the washing tub, and the other side is connected to one side of the condenser through the drying fan. The other side of the condenser is connected to the washing tub. A heater is arranged in the heating duct. When drying clothes, the airflow generated by the drying fan is heated by the heater in the heating duct to form a high-temperature airflow. The high-temperature airflow flows through the clothes to be dried in the washing tub, heats the clothes, and takes away the evaporated moisture, so that the clothes are dried quickly.

[0082] The clothes dryer or washer-dryer of this embodiment uses a lint filter to remove lint from the air flowing in the machine body to avoid contamination of clothes. The lint filter includes: a first filter component and a second filter component with a lint filtering function, and the first filter component and the second filter component are detachably and fixedly connected to each other through a connecting device. The connecting device has a simple structure and flexible installation, which is more convenient for users to disassemble and install, and facilitates users to maintain the filter layers separately, which is more conducive to timely and effective cleaning of the lint filter; at the same time, the connecting device is firmly connected, meeting the connection requirements of the filter using multiple filtration, so that the lint filter can use filter layers with different filtration efficiencies to filter lint in the clothing processing device, thereby enhancing the efficiency and reliability of lint filtering.

[0083] The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modify the technical contents suggested above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the solution of the present invention.
