Description

Technical Field

[0001] This utility model relates to the field of clothing processing equipment, and more specifically, to a lint filter assembly for a clothes dryer and a clothes dryer having the same. Background Technology

[0002] With the increasing demand from modern families for energy efficiency and environmental protection, heat pump dryers have gradually become a popular household appliance. Compared with traditional heated dryers, heat pump dryers have higher energy efficiency and lower emissions. Furthermore, they provide a gentler hot air temperature, causing less damage to clothes.

[0003] During the drying process of a heat pump dryer, clothes are prone to lint. Lint can easily flow with the airflow and enter the air duct, eventually adhering to the surface of the evaporator, condenser, and other components. This reduces the dryer's efficiency and can affect its lifespan.

[0004] Chinese patent CN201710845778.6 discloses a lint collection device and a clothes dryer. The lint collection device includes: a main body, which is a cavity structure with an air inlet at one end and a first filter screen at the other end and on its side wall; and a second filter element, rotatably disposed within the cavity structure, with one end connected to one side wall of the cavity structure. When the second filter element moves to a first position, its other end contacts the other side wall of the cavity structure, dividing the cavity structure into a first cavity and a second cavity. The air inlet is located within the first cavity. This patent provides a lint collection device with a main body and a second filter element. The rotatable second filter element is disposed within the cavity structure. When the second filter element rotates to the first position, it divides the cavity structure into a first cavity and a second cavity, ensuring both a dual-cavity structure and sufficient airflow, thereby improving the lint collection effect. However, because there are many extremely fine hairs in the hot air, these hairs can easily pass through the mesh of the filter screen and thus adhere to the evaporator and condenser, affecting their heat exchange efficiency and reducing their service life.

[0005] In addition, in order to solve the problem of lint, some manufacturers have installed filter cotton on the side of the ventilation duct near the evaporator and opened a door at the corresponding position on the front of the dryer so that users can take out the filter cotton for cleaning. This method not only destroys the overall aesthetics of the dryer, but also makes it inconvenient for users to operate because the heat pump system is usually located on the base and the door opening position is low. Utility Model Content

[0006] The problem solved by this invention is that, in the prior art, the structure used to filter lint in a clothes dryer is not easy to remove for cleaning.

[0007] To solve the above problems, this utility model provides a lint filter assembly for a clothes dryer, including a lint box and a filter sponge. The lint box includes two or more filter parts, which are nested together to form several filter chambers. A filter sponge is provided on the downwind side of the lint box, and the filter sponge is used to filter out fine lint that passes through the filter parts.

[0008] By setting up two or more filtration stages, the lint content in the hot air can be greatly reduced. Furthermore, the filter sponge 700 with extremely small pore size and variable pore orientation can effectively remove fine lint after passing through the two filtration stages, significantly improving lint removal efficiency, maintaining the cleanliness of the condenser and evaporator surfaces, ensuring the airtightness of the drying duct, and improving drying efficiency.

[0009] Furthermore, the lint box includes a first filter section, a second filter section, and a third filter section. The second filter section is sleeved on the outside of the first filter section, and the third filter section is sleeved on the outside of the second filter section. The first filter section defines a first filter cavity, the first filter section and the second filter section cooperate to define a second filter cavity, and the second filter section and the third filter section cooperate to define a third filter cavity. Each of the first filter section and the second filter section is provided with a plurality of filter screens.

[0010] With the above setup, the airflow passing through the fabric treatment chamber is directly introduced into the first filter chamber, then passes through the second and third filter chambers in sequence, and then enters the drying air duct, thus forming a three-layer filtration structure. This effectively collects lint in the lint box. In addition, the filter sponge on the downwind side can filter out the fine lint that passes through the above filter chambers, thereby effectively preventing lint from escaping into the heat pump system and significantly improving the working efficiency and service life of the heat pump system.

[0011] Furthermore, the first filter section includes a first filter frame and a second filter frame. The first filter frame and the second filter frame are respectively provided with a plurality of first filter screen mounting frames. The first filter screen mounting frames are used to install the first filter screen. The first filter frame and the second filter frame are connected through a first filter bottom, and the first filter frame and the second filter frame are respectively rotatable relative to the first filter bottom. A first snap-fit ​​structure is provided between the first filter frame and the second filter frame. The first snap-fit ​​structure is used for the first filter frame and the second filter frame to engage and engage. After the first filter frame and the second filter frame engage and engage, the first filter section is formed.

[0012] The first filter screen is used to filter the hot air in the first filter chamber, thereby performing primary filtration of the lint therein. The filtered hot air and the lint therein enter the second filter chamber for further filtration. When the first snap-fit ​​structure is separated, the first filter part can be rotated and opened. This setting makes the first filter part an easy-to-disassemble structure, so that it is easy to clean the lint it collects when it is opened, and to filter and collect lint when it is snapped shut.

[0013] Furthermore, the second filter section includes a third filter frame, a fourth filter frame, and a top cover. The third and fourth filter frames are each provided with a plurality of second filter screen mounting frames for mounting the second filter screens. The top cover includes a first top cover and a second top cover. The first top cover is integrally formed with the third filter frame, and the second top cover is integrally formed with the fourth filter frame. The ends of the third and fourth filter frames away from the top cover are connected through a second filter bottom, and the third and fourth filter frames are respectively rotatable relative to the second filter bottom. A second snap-fit ​​part is provided on the first top cover, and a first snap-fit ​​part is provided on the second top cover. The first snap-fit ​​part and the second snap-fit ​​part engage to form the second filter section.

[0014] The second filter screen is used to filter the hot air in the second filter chamber, thereby performing secondary filtration of the lint. The filtered hot air and the lint enter the third filter chamber for further filtration. The first snap-fit ​​part and the second snap-fit ​​part cooperate to form a second snap-fit ​​structure. When the second snap-fit ​​structure is separated, the second filter part can be rotated and opened. This setting makes the second filter part an easy-to-disassemble structure, which is convenient for taking out and putting in the first filter part, and also convenient for cleaning the lint collected when it is opened. When it is locked, it filters and collects lint, which is simple and convenient.

[0015] Furthermore, the third filter section includes a fifth filter frame and a sixth filter frame. Each of the fifth and sixth filter frames has a plurality of third filter screen mounting frames for mounting the third filter screen. The fifth and sixth filter frames are connected via a third filter base, and each of the fifth and sixth filter frames is rotatable relative to the third filter base. A third snap-fit ​​structure is provided between the fifth and sixth filter frames for engaging and locking the fifth and sixth filter frames. The engaging and locking of the fifth and sixth filter frames forms the third filter section.

[0016] The third filter screen is used to filter the hot air in the third filter chamber, thereby performing three-stage filtration of the lint. The filtered hot air and the lint are blown onto the filter sponge for further filtration. When the third snap-fit ​​structure is separated, the third filter section can be rotated and opened. This design makes the third filter section easy to disassemble, which is convenient for taking out and putting in the second filter section, and also makes it easy to clean the lint collected when it is opened. When it is snapped shut, it filters and collects lint, which is simple and convenient.

[0017] Furthermore, the filter sponge is disposed in the drying air duct below the lint box.

[0018] With the above settings, the hot air, after being filtered through the multi-stage lint box, can flow to the condenser and evaporator only after being filtered through the filter sponge. This effectively removes lint from the hot air, ensuring the cleanliness of the heat pump system and improving drying efficiency.

[0019] Furthermore, the third filter section includes a circumferential sidewall and a sponge clamping section. A perforated third filter bottom is provided on the circumferential sidewall. The sponge clamping section is located on the lower side of the third filter bottom. A filter sponge is clamped between the sponge clamping section and the third filter bottom. The sponge clamping section can open or close relative to the third filter bottom.

[0020] The circumferential sidewalls are enclosed plates. After the hot air filtered by the second filter enters the cavity of the third filter, it can only be discharged through the filter sponge clamped at the bottom, thus ensuring the cleanliness of the circulating air, preventing lint from entering the heat pump system, and improving drying efficiency.

[0021] Furthermore, a third snap-fit ​​portion is provided on the sponge clamping portion, and a fourth snap-fit ​​portion is provided on the circumferential sidewall. The third snap-fit ​​portion and the fourth snap-fit ​​portion engage to clamp the filter sponge together with the third filter bottom.

[0022] In this configuration, the circumferential sidewall of the third filter section is a closed annular structure, which allows the lint filter component to form a closed space while filtering, thereby replacing the air duct. This eliminates the need for an additional air duct on the front support, achieving the same effect, simplifying the structure of the dryer and reducing its cost.

[0023] This utility model also discloses a clothes dryer, which includes the lint filter assembly described above.

[0024] The advantages of the dryer described above over the prior art are the same as those of the lint filter component in the dryer described above, and will not be repeated here.

[0025] Furthermore, the dryer includes a front door, and a front support is provided on the front door at a position corresponding to the door body, and the lint filter assembly is provided on the front support.

[0026] This feature allows users to easily remove the lint filter for cleaning simply by opening the dryer door, making the operation simple and convenient and enhancing the user experience.

[0027] Compared with the prior art, the lint filter assembly for a clothes dryer and the clothes dryer having the same as described in this utility model have the following advantages:

[0028] (1) By setting up the first filter section, the second filter section and the third filter section, a multi-layer filtration system is formed. Combined with the setting of the filter sponge, it can effectively prevent lint from entering the heat pump system, thereby improving its operating efficiency and service life.

[0029] (2) By setting the lint filter assembly on the front support, users can operate it by simply opening the dryer door when they need to clean the lint filter assembly, which simplifies the operation steps and improves the user experience.

[0030] (3) By setting the circumferential sidewall and sponge clamping part in the third filter section, multiple filtration is achieved while replacing the setting of filter sponge in the air duct, simplifying the setting structure and reducing product cost. Attached Figure Description

Detailed Implementation

[0049] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the described embodiments are only some, not all, of the embodiments of this utility model. The specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. It should be noted that, unless otherwise specified, the embodiments and features described in the present utility model can be combined with each other.

[0050] The following describes in detail, with reference to the accompanying drawings, a lint filter assembly for a clothes dryer and a clothes dryer having the same assembly as embodiments of the present invention.

[0051] Example 1

[0052] This embodiment provides a lint filter assembly for a clothes dryer, such as... Figures 1-15 As shown, it includes a lint box and a filter sponge 700. The lint box includes two or more filter sections, which are nested together to form several filter chambers. A filter sponge 700 is provided on the downwind side of the lint box. The filter sponge 700 is used to filter out fine lint that passes through the filter sections.

[0053] In existing technologies, hot air in dryers is circulated during the drying process to reduce energy consumption and improve drying efficiency. However, fabrics generate a large amount of lint during drying, which adheres to the condenser and heat exchanger with the circulating hot air, severely affecting heat exchange efficiency. This necessitates the installation of corresponding cleaning devices for the condenser and heat exchanger, which affects the sealing performance of the air duct and makes the dryer's structure more complex and costly. In this application, the use of two or more stages of filtration significantly reduces the lint content in the hot air. Furthermore, the use of filter sponges 700 with extremely small pore sizes and varied pore orientations effectively removes fine lint after passing through the two stages of filtration, significantly improving lint removal efficiency, maintaining the cleanliness of the condenser and evaporator surfaces, ensuring the airtightness of the drying air duct, and enhancing drying efficiency. It should be noted that the filter sponge 700 provided on the downwind side of the lint box means that the filter sponge 700 is provided in the drying air duct on the downwind side of the lint box, and / or the filter sponge 700 is provided at the air outlet of the lint box.

[0054] As one of the alternative embodiments, such as Figures 1-11As shown, the lint box includes a first filter section 100, a second filter section 200, and a third filter section 300. The second filter section 200 is sleeved on the outside of the first filter section 100, and the third filter section 300 is sleeved on the outside of the second filter section 200. The first filter section 100 defines a first filter chamber, the first filter section 100 and the second filter section 200 cooperate to define a second filter chamber, and the second filter section 200 and the third filter section 300 cooperate to define a third filter chamber. Several filter screens are provided on each of the first filter section 100 and the second filter section 200. Through this arrangement, the airflow from the fabric processing chamber is directly introduced into the first filter chamber, then sequentially passes through the second and third filter chambers, and then enters the drying duct, thus forming a three-layer filtration structure. This effectively collects lint in the lint box. Furthermore, the filter sponge 700 on the downwind side can filter out fine lint that has passed through the filter chambers, effectively preventing lint from escaping into the heat pump system and significantly improving the operating efficiency and service life of the heat pump system. It should be noted that the third filter section 300 may or may not have a filter screen, depending on the arrangement of the subsequent filter sponge 700, and will not be limited here.

[0055] Among them, such as Figure 3 , Figure 7 As shown, the first filter section 100 includes a first filter frame 110 and a second filter frame 120. The first filter frame 110 and the second filter frame 120 are respectively provided with a plurality of first filter screen mounting frames. The first filter screen mounting frames are used to install the first filter screen. The first filter frame 110 and the second filter frame 120 are connected through a first filter base 130, and the first filter frame 110 and the second filter frame 120 are respectively rotatable relative to the first filter base 130. A first snap-fit ​​structure is provided between the first filter frame 110 and the second filter frame 120. The first snap-fit ​​structure is used for the first filter frame 110 and the second filter frame 120 to engage and engage. After the first filter frame 110 and the second filter frame 120 engage and engage, the first filter section 100 is formed. The first filter screen is used to filter the hot air in the first filter chamber, thereby performing primary filtration of the lint therein. The filtered hot air and the lint therein enter the second filter chamber for further filtration. When the first snap-fit ​​structure is separated, the first filter part 100 can be rotated and opened. This setting makes the first filter part 100 an easy-to-disassemble structure, so that it is easy to clean the lint it collects when it is opened, and to filter and collect lint when it is snapped shut.

[0056] like Figure 4 , Figure 5 , Figure 7As shown, the second filter section 200 includes a third filter frame 210, a fourth filter frame 220, and a top cover 230. The third filter frame 210 and the fourth filter frame 220 are each provided with a plurality of second filter screen mounting frames for mounting second filters. The top cover 230 includes a first top cover 231 and a second top cover 232. The first top cover 231 is integrally formed with the third filter frame 210, and the second top cover 232 is integrally formed with the fourth filter frame 220. The ends of the third filter frame 210 and the fourth filter frame 220 away from the top cover 230 are connected via a second filter bottom, and the third filter frame 210 and the fourth filter frame 220 are respectively rotatable relative to the second filter bottom. A second snap-fit ​​portion 234 is provided on the first top cover 231, and a first snap-fit ​​portion 233 is provided on the second top cover 232. The first snap-fit ​​portion 233 and the second snap-fit ​​portion 234 engage to form the second filter section 200. The second filter screen is used to filter the hot air in the second filter chamber, thereby performing secondary filtration of the lint. The filtered hot air and the lint enter the third filter chamber for further filtration. The first snap-fit ​​part 233 and the second snap-fit ​​part 234 cooperate to form a second snap-fit ​​structure. When the second snap-fit ​​structure is separated, the second filter part 200 can be rotated and opened. This setting makes the second filter part 200 an easy-to-disassemble structure, which is convenient for taking out and putting in the first filter part 100, and also convenient for cleaning the lint collected when it is opened. When it is locked, it filters and collects lint, which is simple and convenient.

[0057] Specifically, a first limiting structure is provided between the first filter section 100 near the windward side and the second filter section 200. This first limiting structure is used to limit the installation of the first filter section 100. Specifically, a first protruding edge is provided near the windward side of the first filter section 100, extending outwards from the outer periphery of the first filter section 100. A corresponding stepped structure is provided on the inner wall of the second filter section 200, and the first protruding edge and the stepped structure are fitted together. This arrangement facilitates the fitting and limiting of the first filter section 100 and the second filter section 200, aids in the limiting installation of the first filter section 100, and also facilitates the formation of a second filter cavity between them.

[0058] Multiple filter holes are provided on the first top cover 231 and / or the second top cover 232. These filter holes can directly filter out larger impurities, preventing them from entering the lint filter assembly and clogging the filter screen.

[0059] Better, such as Figure 7As shown, a handle hole 240 is provided on each side of the first latching portion 233 and the second latching portion 234. The handle hole 240 facilitates the user's gripping of the lint box for removal or installation. It should be understood that the lint box will gradually clog the filter holes on the filter screen after collecting lint for a long time. The above-mentioned design facilitates the user to remove the lint box for cleaning the lint filter assembly.

[0060] like Figure 3 , Figures 8-11 As shown, the third filter section 300 includes a fifth filter frame 310 and a sixth filter frame 320. Each of the fifth filter frame 310 and the sixth filter frame 320 is provided with a plurality of third filter screen mounting frames for mounting third filters. The fifth filter frame 310 and the sixth filter frame 320 are connected by a third filter base 330, and each of the fifth filter frame 310 and the sixth filter frame 320 is rotatable relative to the third filter base 330. A third snap-fit ​​structure is provided between the fifth filter frame 310 and the sixth filter frame 320 for engaging and locking the fifth filter frame 310 and the sixth filter frame 320. After engaging and locking, the fifth filter frame 310 and the sixth filter frame 320 form the third filter section 300. The third filter screen is used to filter the hot air in the third filter chamber, thereby performing three-stage filtration of the lint. The filtered hot air and the lint are blown onto the filter sponge 700 for further filtration. When the third snap-fit ​​structure is separated, the third filter section 300 can be rotated and opened. This setting makes the third filter section 300 an easy-to-disassemble structure, which is convenient for taking out and putting in the second filter section 200, and also convenient for cleaning the lint collected when it is opened. When it is snapped closed, it filters and collects lint, which is simple and convenient.

[0061] Optionally, a protruding edge is provided at the top of the third filter section 300. This protruding edge is used for assembly with the second filter section 200 and also for the installation of the lint filter assembly. Specifically, a corresponding countersunk platform is provided on the front support 600 of the dryer. The protruding edge is configured to cooperate with the countersunk platform, effectively improving the installation efficiency of the lint filter assembly. In addition, a recessed platform is provided on the second filter section 200 to cooperate with the protruding edge, and the protruding edge is limited by cooperating with the recessed platform. Through the above configuration, the protruding edge can be used for both the installation of the lint filter assembly in the dryer and the assembly of the third filter section 300 with the second filter section 200.

[0062] Specifically, in this embodiment, the filter sponge 700 is disposed in the drying air duct below the lint box. In the above structure, the filter sponge 700 is disposed relatively independently from the lint box. This arrangement ensures that the hot air, after being filtered through multiple stages by the lint box, is further filtered by the filter sponge 700 before flowing to the condenser and evaporator. This effectively removes lint from the hot air, ensuring the cleanliness of the heat pump system and improving drying efficiency. It should be noted that the filter sponge 700 is disposed near the bottom of the lint box, facilitating removal and cleaning of the filter sponge 700 when cleaning the lint box. This avoids the need for a door at the corresponding position on the front of the dryer, maintaining the dryer's aesthetics and facilitating operation.

[0063] Example 2

[0064] This embodiment provides a lint filter assembly for a clothes dryer, such as... Figure 12 As shown, the lint filter assembly has a basically the same structure as that in Embodiment 1, except that the structure of the third filter section 300 is different.

[0065] In this embodiment, the third filter section 300 includes a circumferential sidewall 350 and a sponge clamping section 340. A perforated third filter bottom 330 is provided on the circumferential sidewall 350. The sponge clamping section 340 is located below the third filter bottom 330, and a filter sponge 700 is clamped between the sponge clamping section 340 and the third filter bottom 330. The sponge clamping section 340 can be opened or closed relative to the third filter bottom 330. It should be understood that the circumferential sidewall 350 is a closed plate. After the hot air filtered by the second filter section 200 enters the cavity of the third filter section, it can only be discharged through the filter sponge 700 clamped at the bottom, thereby ensuring the cleanliness of the circulating air, preventing lint from entering the heat pump system, and improving drying efficiency.

[0066] Optionally, a third engaging portion is provided on the sponge clamping part 340, and a fourth engaging portion is provided on the circumferential sidewall 350. The third engaging portion and the fourth engaging portion engage with each other, so that the sponge clamping part 340 and the third filter base 330 clamp the filter sponge together. In this configuration, the circumferential sidewall 350 of the third filter part 300 is a closed annular structure, which can form a closed space for the lint filter assembly while filtering, thereby replacing the air duct. The same effect can be achieved without setting an additional air duct on the front support 600, simplifying the structure of the dryer and reducing its cost. Regarding the installation structure of the filter sponge 700, a corresponding stepped installation structure or slot structure can be provided on the front support 600. For details, please refer to the prior art, which will not be elaborated here.

The lint filter assembly is disposed on the front support 600. This design allows users to easily remove the lint filter assembly for cleaning by opening the dryer door, making operation simple and convenient and improving the user experience.
