Description

Drying equipment and washing equipment

[0001] This application claims priority to Chinese Patent Application No. 2024116872530, filed on November 22, 2024, entitled “Drying Apparatus and Washing Equipment”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This invention relates to the field of washing technology, specifically providing a drying device and a washing equipment. Background Technology

[0003] Washer-dryer combos are designed to provide modern families with convenient laundry washing and drying services. However, lint from clothes shed during the drying process can easily adhere to the heater with the airflow, affecting its performance and drying effect. To solve this problem, a filter is installed at the air inlet of the heater in the drying system.

[0004] For ease of cleaning, filters are typically pull-out and housed within the washer-dryer combo. In some related technologies, the filter's sidewalls are often designed as filter mesh frames. However, while this multi-faceted perforated filter optimizes filtration efficiency and ventilation, it still has a significant drawback: lint, captured during the drying process, accumulates at the various openings. This accumulated lint is easily dislodged from the openings by gravity or minor vibrations during the extraction process when the user cleans the filter. This dislodged lint then enters the drying duct, not only increasing the difficulty of cleaning but also potentially adhering to the heater, leading to reduced heating efficiency and even affecting the overall performance of the equipment.

[0005] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0006] The present invention aims to solve the above-mentioned technical problems, namely, to solve the problem that existing filters easily cause lint to fall into the air duct and contaminate the heater during use.

[0026] In the locked position, the first end and the second end are respectively pressed against the inner wall of the receiving groove and the stop portion under the elastic force of the first elastic member;

[0027] Pressing the first end causes the rotating arm to rotate and drives the second end to slide from the stop to the guide so that the filter box is separated from the housing.

[0028] Optionally, the filtering component further includes:

[0029] The second elastic member has one end connected to the filter box and the other end connected to the housing.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0047] Please refer to Figures 1-3, which show a drying apparatus according to an embodiment of this application. The drying apparatus is disposed in the housing 5 of a device (e.g., a washer-dryer combo) in which the drying apparatus is applied.

[0048] Specifically, the drying device includes a housing 1, a heating component 2, a filter component 3, and a fan 4, etc., and aims to solve the problem in the prior art that the filter easily causes lint to fall off and contaminate the heating component 2.

[0049] Specifically, the housing 1 is designed with an air inlet 10 and an air outlet to ensure the airflow path during the drying process. The heating element 2 is located inside the housing 1, providing the necessary heat energy for the drying process. To prevent lint from directly adhering to the heating element 2 and affecting its performance, a filter element 3 is placed between the air inlet 10 and the heating element 2. The fan 4 drives the airflow from the air inlet 10 through the first opening 311 into the filter box 31, and guides the airflow sequentially through the filter element and the second opening 312, before entering the heating element 2 for heating. The direction of airflow is indicated by the arrows in Figure 3.

[0050] Furthermore, the filter assembly 3 includes a filter box 31 and a filter element disposed inside the filter box 31. The housing 1 is also provided with a pull-out opening, through which the filter box 31 can be pulled out and disposed inside the housing 1.

[0051] Furthermore, the filter box 31 adopts a box structure with multiple closed sidewalls, with a first opening 311 only on the sidewall facing the air inlet 10 and a second opening 312 on the sidewall facing the heating assembly 2. The filter element is positioned adjacent to the second opening 312. This design allows airflow to enter through the first opening 311 when passing through the filter box 31, then be efficiently intercepted by the filter element, and finally flow out through the second opening 312. In this process, tiny lint and other impurities can be effectively trapped in the filter element, thereby preventing them from contaminating the heating assembly 2.

[0052] Compared to the traditional design using a filter frame 32, this semi-enclosed filter box 31 can significantly reduce the accumulation of lint and other impurities inside the filter box 31, thereby preventing these impurities from falling into the air duct during the process of pulling out the filter box 31 and reducing pollution in the air duct.

[0053] In one embodiment, the filter element consists of a filter frame 32 and a filter layer. The filter frame 32 supports and fixes the filter layer, which effectively filters lint and other impurities, preventing these impurities from entering the heating area of ​​the device. The filter layer is typically a filter material, such as glass fiber, synthetic fibers (e.g., polyester and polypropylene), or non-woven fabric.

[0054] Specifically, referring to Figure 4, one end of the filter frame 32 is hinged to the filter box 31. This hinged design allows the filter frame 32 to be opened and closed flexibly, making it convenient for users to clean and maintain it when needed.

[0055] The filter layer is mounted on the filter frame 32 and located on the side away from the heating element 2, i.e., inside the filter box 31. This ensures that lint and other impurities are not only adsorbed onto the filter layer but also prevent them from easily falling into other parts of the drying unit or the air duct. Especially when cleaning or replacing the filter layer, the user can remove the entire filter box 31 along with the filter layer. This not only prevents lint from falling into the air duct but also thoroughly cleans the filter layer.

[0056] In one embodiment, the drying apparatus further includes a flow guiding component 33 disposed inside the housing 1 and located between the air inlet 10 and the heating component 2. The flow guiding component 33 is used to guide the flow path of the airflow, thereby improving the drying effect of the drying apparatus.

[0057] Specifically, through the precise guidance of the flow guide component 33, the airflow can avoid disordered flow and the generation of eddies. This directional flow enhances heating efficiency, making the entire heating process more uniform and efficient.

[0058] Furthermore, the precise guidance of the airflow guide component 33 allows the airflow to pass through the heating zone in a smoother and more uniform manner, which helps to improve the uniformity of airflow heating and thus improve the drying effect of the drying device.

[0059] In one possible implementation, referring to Figure 3, the flow guiding component 33 is disposed inside the filter box 31 and close to the second opening 312. In this way, the airflow can enter the filter box 31 through the first opening 311, then flow through the flow guiding component 33 to achieve airflow diversion, and enter the heating device through the second opening 312.

[0060] In another possible implementation, the flow guiding component 33 is disposed between the second opening 312 and the heating component 2. The airflow, after being filtered by the filter component 3 and flowing out from the second opening 312, can also pass through the heating zone in a smoother and more uniform manner after being guided by the flow guiding component 33, thereby achieving heating of the airflow.

[0061] In a preferred embodiment, referring to 3 and 5, the flow guiding assembly 33 includes a connecting portion 331 and a flow guiding plate connected to the connecting portion 331.

[0062] Specifically, the connecting part 331 is a support frame structure, which is disposed outside the filter box 31 and adjacent to the first opening 311 of the filter box 31. In addition, the support frame is fixedly connected to the housing 1. One end of the guide plate is connected to the connecting part 331, and the other end extends into the interior of the filter box 31 through the first opening 311.

[0063] Furthermore, a space is formed between the guide plate and the bottom wall of the support frame, which allows the filter box 31 to be placed in the space during the pulling process, thus ensuring the effective flow guiding function of the guide plate and avoiding interference between the filter box 31 and the guide plate.

[0064] Furthermore, compared to traditional designs, such as structures where the flow guide is located inside the filter box 31, the innovative design in this embodiment significantly simplifies the internal structure of the filter box 31, thereby bringing many advantages.

[0065] Specifically, this simplification makes cleaning the inside of the filter cartridge 31 more convenient and efficient. By reducing the complex flow guidance structure, the filter cartridge 31 has fewer dead corners and hard-to-clean areas, reducing the impact of long-term accumulated dirt and dust on the filtration effect. This allows users to more easily clean every corner of the filter cartridge 31 for a thorough cleaning.

[0066] Furthermore, multiple guide plates are arranged side by side, and guide channels are formed between adjacent guide plates and between the guide plates and the inner wall of the filter box 31. The airflow enters the interior of the filter box 31 along these guide channels, which helps to reduce turbulence and eddies in the airflow inside the filter box 31 and ensures that the airflow enters the heating device in a smooth and uniform manner.

[0067] Referring to Figure 5 and Figure 3, the following explanation uses the example of setting two guide vanes. The two guide vanes are the first guide vane 332 and the second guide vane 333, with the second guide vane 333 located near the second opening 312.

[0068] The first guide plate 332 and the second guide plate 333 both extend into the filter box 31, forming three guide channels inside the filter box 31. The airflow enters the filter box 31 along these three guide channels.

[0069] Furthermore, both the first guide plate 332 and the second guide plate 333 have a curved portion at one end inside the filter box 31 that faces the second opening 312. This curved design helps guide the airflow and ensures a smooth transition, so that the airflow can flow accurately to the second opening 312.

[0070] In addition, the first deflector 332 is longer than the second deflector 333. This difference in length helps to guide the airflow naturally toward the second opening 312 when it enters along this channel, reducing possible airflow dispersion and turbulence.

[0071] In one embodiment, the filter assembly 3 is further provided with a locking mechanism located at the pull-out end of the filter box 31. This locking mechanism can securely lock the filter box 31 inside the housing 1, ensuring the stability of its connection. When it is necessary to replace or clean the filter assembly 3, the locking mechanism can release the filter box 31, allowing it to easily detach from the housing 1.

[0072] Specifically, the locking mechanism can take many forms, such as mechanical snap-on, magnetic snap-on, or slide rail locking.

[0073] It should be noted that this embodiment uses the locking structure to lock the filter box 31 onto the housing 1 as an example for detailed explanation. This design demonstrates how the locking mechanism ensures the stability of the filter box 31 inside the device. However, the application of the locking structure is not limited to this. The locking structure can also lock the filter box 31 in a wider range of applications, such as locking it onto the housing 5 of a washer-dryer combo, or onto the outer shell of other devices.

[0074] In one embodiment, referring to Figures 6-8, the filter box 31 is provided with a receiving groove 313 on the side near the pull-out end, and the housing 1 is provided with a limiting groove 11 at the corresponding position. The limiting groove 11 is provided with a stop part 112 and a guide part 111.

[0075] Furthermore, a rotating arm 314 is provided inside the receiving groove 313, and the rotating arm 314 can rotate around its axis. The two sides of the axis of rotation of the rotating arm 314 are respectively the first end 3141 and the second end 3142 of the rotating arm 314. The first end 3141 is located inside the receiving groove 313, while the second end 3142 has a locking protrusion 3143, which can slide within the limiting groove 11.

[0076] Referring to Figure 6, the two key positions of the rotating arm 314 in the filter box 31, namely locking and unlocking, are shown in detail.

[0077] Furthermore, a first elastic element 315 is connected between the inner wall of the receiving groove 313 and the first end 3141, so that the combination of the first end 3141 and the first elastic element 315 is similar to a spring button. The function of the first elastic element 315 is to provide a stable and lasting elastic force, so that the rotating arm 314 is held in a specific position in its natural state.

[0078] Specifically, in the locked position, the first end 3141 of the rotating arm 314 abuts against the inner wall of the receiving groove 313 under the elastic force of the first elastic member 315, while the locking protrusion 3143 of the second end 3142 is limited to the stop portion 112, forming a tight locking state.

[0079] When unlocking is required, the user can gently press the first end 3141 of the rotating arm 314 to start it rotating (i.e., rotating counterclockwise as shown by the arrow in Figure 6). This rotation causes the locking protrusion 3143 of the second end 3142 to slide from the stop part 112 to the guide part 111, and then the filter box 31 is pulled out, finally unlocking the filter box 31 from the housing 1.

[0080] When the user completes the unlocking process and releases the first end 3141 of the rotating arm 314, driven by the rebound force of the first elastic element 315, the first end 3141 will move toward the inner wall of the receiving groove 313 and eventually abut against the side wall of the receiving groove 313 to achieve a stable state.

[0081] When the user needs to relock the filter box 31 onto the housing 1, pressing the first end 3141 of the rotating arm 314 causes the rotating arm 314 to rotate counterclockwise around its axis. The locking protrusion 3143 of the second end 3142 of the rotating arm 314 engages in the limiting groove 11. When the first end 3141 is released, under the elastic force of the first elastic element 315, the locking protrusion 3143 slides along the guide portion 111 to the stop portion 112 and stabilizes in that position, thereby relocking the filter box 31 onto the housing 1.

[0082] In one embodiment, the filter assembly 3 further includes a second elastic member 316, one end of which is connected to the filter box 31 and the other end of which is connected to the housing 1. In the locked position, the second elastic member 316 abuts against the filter box 31 and the housing 1. When the filter box 31 is unlocked, the second elastic member 316 can provide a boosting force to make the filter box 31 move in a direction away from the housing 1.

[0083] Specifically, in the locked position, the second elastic element 316 remains in its pre-compressed state. When the first end 3141 is pressed to initiate the unlocking process, the elastic force of the second elastic element 316 is converted into an outward thrust, which assists the filter box 31 in detaching from the housing 1 through the contact point between the filter box 31 and the housing 1. This thrust ensures that the filter box 31 can be smoothly separated from the housing 1, reducing resistance and inconvenience during operation, and making the replacement or maintenance of the filter box 31 simpler and smoother.

[0084] In a preferred embodiment, referring to FIG9, a guide channel 317 is provided on the outer side wall of the filter box 31, and a stop (not shown in the figure) is provided on the inner side wall of the housing 1. The second elastic member 316 is embedded in the guide channel 317 to ensure that it can maintain a straight line and stability during the movement between the filter box 31 and the housing 1.

[0085] Specifically, when the filter box 31 is in the locked position with the housing 1, one end of the second elastic member 316 abuts against the side wall of the guide channel 317. This abutment forms a stable support point, allowing the second elastic member 316 to withstand and transmit the force required during the locking process. Simultaneously, the other end of the second elastic member 316 makes close contact with a stop on the housing 1. The stop is designed to prevent the filter box 31 from accidentally sliding or loosening in the locked state, further strengthening the fixation of the filter box 31 within the housing 1.

[0086] When the user presses the first end 3141 of the rotating arm 314 to release the lock, the second elastic element 316, due to its pre-compressed state, can quickly release the thrust, assisting the filter box 31 to slide smoothly out of the housing 1.

[0087] When the filter box 31 needs to be pushed back into the housing 1, as the filter box 31 is pushed deeper, the guide channel 317 provided on the outer wall of the filter box 31 effectively guides the filter box 31 along a predetermined path, reducing the risk of misalignment during installation. Gradually, one end of the second elastic member 316 begins to approach the stop member inside the housing 1, and as the filter box 31 is pushed further in, one end of the elastic member gradually contacts the stop member and is further compressed, while its other end tightly abuts against the inner wall of the guide channel 317.

[0088] In the locked state, the second elastic element 316 remains in a compressed state and forms a balance point between the filter box 31 and the housing 1, ensuring the stable fixation of the filter box 31, while also reserving elastic buffer for the next unlocking action.

[0089] By providing a guide channel 317 on the outer wall of the filter box 31, the movement of the second elastic element 316 can be effectively guided, so that it remains stable during the locking and unlocking process of the filter box 31 and the housing 1, avoiding accidental detachment or displacement, thereby improving the reliability and ease of operation of the entire filter assembly 3.

[0090] It should be noted that, in this design, the side of the filter box 31 closest to the stop is preferably a stepped sidewall to prevent the filter box 31 from interfering with the stop during insertion, thereby ensuring a smooth insertion process.

[0091] In another preferred embodiment, referring to FIG9, a groove is provided on the guide channel 317, and a sliding member 318 is slidably connected on the groove. One end of the second elastic member 316 abuts against the inner wall of the guide channel 317, and the other end abuts against the sliding member 318. When the filter box 31 is inserted into the housing 1, the sliding member 318 first abuts against the stop member. As the insertion goes deeper, the second elastic member 317 is gradually compressed.

[0092] The design of the slider 318 and the groove can prevent interference between the filter box 31 and the stop, thus ensuring a smooth insertion process.

[0093] The present invention also provides a washing device, including the drying device as described above, and the drying device is disposed in the housing 5 of the washing device. Since the drying device has the above-mentioned technical effects, the washing device using the drying device also has the above-mentioned effects, which will not be described again here.

However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the scope of protection of the present invention.
