Description

Technical Field

[0001] The present invention relates to the technical field of clothing processing, and in particular to a clothes drying device. Background Art

[0002] Drying equipment can generate hot air flow in the circulating air duct. When the hot air flow passes through the clothes, it can take away the moisture on the surface of the clothes and dry the clothes. During the drying process, the clothes will produce a lot of fine hair. The hair will flow in the circulating air duct with the air flow. If it is not filtered, these hair will adhere to the inner wall of the air duct and the fan and other components installed in the air duct. Over time, it is easy to breed bacteria and mildew. For heat pump dryers, it will also block the evaporator, condenser and other precision components, causing the heat exchange function of the evaporator and condenser to be reduced or even fail.

[0003] Therefore, for heat pump type dryers, in order for the evaporator and condenser to work efficiently throughout their lifespan, a filter will be added to the front side of the base. However, most of the existing filters need to be taken out and cleaned after multiple operating steps, and users are likely to not clean them or take a long time to clean them. The blockage caused by the long-term uncleaning of the filters affects the patency of the entire air duct, causing the performance of the evaporator and condenser to be greatly reduced, and the drying time to be longer. In response to this problem, some dryers may directly ignore the reduction in efficiency of the product in later use, and thus cancel the filters in front of the two devices to avoid the problem of blocked air ducts. In other words, existing dryers cannot take into account both the functions of filtering lint and ensuring smooth air ducts, and the user experience is poor.

[0043] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0044] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" 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, it can be the internal connection of two elements or the interaction relationship between two elements.

[0046] In the description of this embodiment, the terms "upper", "lower", "left", "right" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operate in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0047] like Figure 1 and Figure 2 As shown, this embodiment provides a clothes drying device, such as a clothes dryer, a washer-dryer, etc. The clothes drying device includes a drying air duct 1 and a filter device 2 arranged in the drying air duct 1, and the filter device 2 can filter the airflow. Figure 3 As shown, the filter device 2 includes a filter assembly 21 and a support assembly 22. The filter assembly 21 is arranged around the support assembly 22 in a cyclic manner. The airflow in the drying air duct 1 flows through the opposite sides of the filter assembly 21 in sequence. The support assembly 22 can clean the wire scraps on the filter assembly 21 in transit. That is, the filter assembly 21 is arranged around the support assembly 22 in a ring and can be cyclically transported relative to the support assembly 22.

[0048] By arranging the filter device 2 in the drying air duct 1, the airflow in the drying air duct 1 can be filtered. Specifically, since the filter assembly 21 of the filter device 2 is wound on the support assembly 22, the airflow needs to flow through the opposite sides of the filter assembly 21, that is, the airflow is filtered by two layers of filter mesh, which effectively improves the filtering accuracy and ensures the cleanliness of the airflow in the drying air duct 1. When the airflow flows through the filter assembly 21, the mixed wire scraps therein adhere to the filter assembly 21. When the filter device 2 needs to be cleaned, the filter assembly 21 is driven to circulate relative to the support assembly 22. At this time, the support assembly 22 can clean the wire scraps attached to the filter assembly 21 during the transmission process, so as to avoid excessive wire scraps clogging the mesh of the filter assembly 21, and prevent the filter device 2 from blocking the flow of airflow due to being not cleaned after long-term use.

[0049] That is, the filter device 2 in this embodiment can achieve self-cleaning through the movement of the filter mesh assembly 21 relative to the support assembly 22, which can not only effectively filter the lint in the drying duct 1, but also ensure the smooth flow of airflow in the drying duct 1, avoid airflow obstruction, ensure the drying effect, and enhance the user experience.

[0050] like Figure 1 and Figure 2 As shown, the direction of the straight arrow in the figure is the flow direction of the airflow, and the filter device 2 is preferably arranged at the air inlet of the drying air duct 1. That is, the airflow entering the drying air duct 1 is first filtered and cleaned by the filter device 2, and then passes through other components to ensure the cleanliness of the inner wall and internal components of the drying air duct 1.

[0051] like Figure 3 and Figure 4 As shown, the filter device 2 also includes a driving mechanism 23, the output end of the driving mechanism 23 is connected to a transmission wheel 24, the filter mesh assembly 21 includes a filter mesh body 211 and a transmission belt 212 arranged on the filter mesh body 211, the filter mesh body 211 is wound around the support assembly 22 to form a ring, the airflow passes through the opposite sides of the filter mesh body 211 and is filtered clean, and the transmission belt 212 is in transmission cooperation with the transmission wheel 24. The driving mechanism 23 can drive the transmission wheel 24 to rotate, and when the transmission wheel 24 rotates, it drives the transmission belt 212 to transmit, and the transmission belt 212 further drives the filter mesh body 211 to circulate relative to the support assembly 22, so that the support assembly 22 cleans the wire scraps attached to the filter mesh body 211.

[0052] Optionally, the transmission wheel 24 is a gear, and a plurality of meshing teeth are distributed circumferentially at intervals on one side of the transmission belt 212 facing the gear, and the meshing teeth mesh with the gear to achieve cyclic transmission of the transmission belt 212. That is, the transmission wheel 24 and the transmission belt 212 constitute a synchronous belt mechanism.

[0053] Specifically, Figure 3 and 5 As shown, a transmission belt 212 is provided at both ends of the filter mesh body 211, and a transmission wheel 24 is provided corresponding to the two transmission belts 212. The two transmission wheels 24 are coaxially connected through a transmission shaft, and one of the transmission wheels 24 is connected to the output end of the driving mechanism 23, so that the driving mechanism 23 can simultaneously drive the two transmission wheels 24 to rotate, and then, the two transmission wheels 24 drive the corresponding transmission belts 212 to transmit synchronously, so as to realize the cyclic transmission of the filter mesh body 211. The arrangement of the two transmission wheels 24 and the two transmission belts 212 makes the operation of the filter mesh body 211 more stable.

[0054] Optionally, in this embodiment, the driving mechanism 23 can rotate forward and reverse to realize the transmission of the filter assembly 21 in two opposite directions, so as to clean more thoroughly. The driving mechanism 23 can be a micro motor.

[0055] See also Figure 4 and Figure 5 The filter device 2 further includes a rotatable pressing wheel 25, and the pressing wheel 25 and the transmission wheel 24 are respectively arranged on opposite sides of the transmission belt 212. When the transmission wheel 24 drives the transmission belt 212 to move, the pressing wheel 25 is driven by the transmission belt to roll with the surface of the transmission belt 212. That is, the transmission belt 212 is sandwiched between the pressing wheel 25 and the transmission wheel 24, which effectively improves the movement accuracy of the transmission belt 212 and can prevent the transmission belt 212 from being separated from the transmission wheel 24.

[0056] Specifically in this embodiment, the transmission wheel 24 is located on the inner side of the transmission belt 212, and the pressure wheel 25 is located on the outer side of the transmission belt 212. Moreover, a pressure wheel 25 is provided on the outer side of each transmission belt 212.

[0057] like Figure 1 and Figure 2 As shown, the drying duct 1 is arranged on the base 3 of the clothes drying device, and the base 3 is provided with a water storage area 31 below the drying duct 1, and the lower end of the filter mesh assembly 21 is at least partially located in the water storage area 31. When the driving mechanism 23 drives the filter mesh body 211 to circulate, the lower end of the filter mesh body 211 passes through the water storage area 31 for water washing, and after one round of transportation, the entire filter mesh body 211 can be washed with water, further improving the cleanliness of the filter device 2.

[0058] Furthermore, the driving mechanism 23 and the transmission wheel 24 are located at the upper end of the filter assembly 21 to prevent the driving mechanism 23 from being immersed in the water storage area 31 and short-circuiting.

[0059] For the heat pump type clothes drying device, a condenser 4 and an evaporator 5 are arranged in the drying air duct 1, see Figure 1 and Figure 2, the filter device 2, the evaporator 5 and the condenser 4 are sequentially distributed along the flow direction of the airflow. The airflow first flows through the filter device 2 for filtration before passing through the evaporator 5 and the condenser 4 for heat exchange, ensuring that no lint is attached to the evaporator 5 and the condenser 4, thereby ensuring the performance and service life of the evaporator 5 and the condenser 4. Furthermore, the water in the water storage area 31 is generated by condensation of the evaporator 5. The evaporator 5 has a relatively low operating temperature due to the absorption of heat by the evaporation of the internal refrigerant medium. When the airflow with a certain temperature flows through the evaporator 5, it condenses into water droplets, which drip into the water storage area 31, and the water storage area 31 of the heat pump type clothes drying equipment can wash the filter mesh 211.

[0060] See also Figure 1 Optionally, the clothes drying device further comprises a pumping assembly 6, and a pumping chamber of the pumping assembly 6 is connected to the water storage area 31. After the filter mesh body 211 is washed, there will be lint in the water in the water storage area 31. The water in the water storage area 31 is pumped out by the pumping assembly 6, and the lint is also pumped out. That is, the condensed water in the bottom water storage area 31 can be pumped out while the cleaned lint can be removed. The structural design is ingenious and reasonable, and has strong practicality.

[0061] Optionally, if the location allows, the pumping assembly 6, the filter device 2, the evaporator 5 and the condenser 4 are arranged on the same straight line, which makes it easier to discharge the wire scraps.

[0062] Optionally, the water suction port of the pumping assembly 6 is located between the filter device 2 and the evaporator 5, so that the water suction port is closer to the water storage area 31 at the bottom of the filter device 2 (this part of the water storage area 31 contains more wire scraps), which can quickly remove the wire scraps and prevent the wire scraps from flowing to other locations with the water flow.

[0063] Optionally, the pumping component 6 is a water pump having sufficient suction force to effectively extract the stored water and wire scraps.

[0064] See also Figure 2 , Figure 3 as well as Figure 5 At least one paddle 26 is disposed on the outside of the filter assembly 21. The paddle 26 is specifically disposed on the filter body 211. The paddle 26 is used to paddle the wire scraps in the water storage area 31 under the drive of the filter assembly 21, so that the wire scraps are scattered, and the wire scraps are prevented from accumulating into a ball and affecting the transmission of the filter assembly 21 and clogging the pumping assembly 6.

[0065] In this embodiment, a paddle 26 is disposed on opposite sides of the filter body 211, and when one paddle 26 is moved to the bottom to pry water, the other paddle 26 is located at the top, and the positions of the two paddles are interchanged after rotating 180 degrees. That is, the wire scraps are pried once every half rotation.

[0066] See also Figure 5The support assembly 22 includes an upper support frame 221 and a lower support frame 222 that are spaced apart, and the filter body 211 is wound around the upper support frame 221 and the lower support frame 222. At least one of the upper support frame 221 and the lower support frame 222 is used to clean the wire scraps on the filter body 211. The space between the upper support frame 221 and the lower support frame 222 allows the airflow to pass smoothly, avoiding blocking the flow of the airflow.

[0067] Specifically, the upper support frame 221 and / or the lower support frame 222 include support blocks. Figure 6 The support block includes an arcuate contact surface 2211, which is in sliding contact with the filter body 211 of the filter assembly 21, and the lower support frame 222 is provided with an inclined surface 2212 on the side facing away from the arcuate contact surface 2211, and the inclined surface 2212 is connected with the arcuate contact surface 2211 to form a scraping edge 2213. The scraping edge 2213 is used to scrape off the wire scraps on the filter body 211 during the circulation of the filter body 211.

[0068] In some embodiments, the upper support frame 221 and the lower support frame 222 are both support blocks, and the scraping edges 2213 on the support blocks can effectively remove the wire scraps attached to the filter body 211.

[0069] Further, see Figure 5 , two upper support frames 221 and two lower support frames 222 are arranged opposite to each other. The two upper support frames 221 above support the two corner positions of the upper end of the filter mesh body 211, and the two lower support frames 222 below support the two corner positions of the lower end of the filter mesh body 211, so that the filter mesh body 211 is approximately in the shape of a square ring. At this time, the upper support frame 221 and the lower support frame 222 each have two scraping edges 2213, and the entire support assembly 22 has 8 scraping edges 2213, which effectively scrapes away wire scraps during the transmission process of the filter mesh body 211. In other embodiments, the upper ends of the two upper support frames 221 can be connected as a whole, leaving only the two scraping edges 2213 at the lower ends, and the two lower support frames 222 can be connected as a whole, and the entire support assembly 22 has 4 scraping edges 2213.

[0070] The wire scraps scraped off by the scraping edge 2213 accumulate at the corresponding position. Some of the accumulated wire scraps can fall into the bottom water storage area 31 under the action of their own gravity, while some of the accumulated wire scraps cannot fall by themselves and can be transmitted to the water storage area 31 through the forward and reverse rotation of the filter mesh body 211, and finally be pumped out by the pumping assembly 6.

[0071] In some other embodiments, the upper support frame 221 may still be a support block having a scraping edge 2213 for scraping off wire scraps. The lower support frame 222 may include a support wheel 223 .

[0072] As one of the solutions, the support wheel 223 can be fixedly arranged in the drying air duct 1. During the circulation and transmission of the filter mesh body 211, the filter mesh body 211 moves relative to the support wheel 223 and slides in contact with the support wheel 223, so that the support wheel 223 can squeeze, clean and crush the wire scraps on the filter mesh body 211.

[0073] As another solution, the support wheel 223 is rotatably disposed in the drying duct 1. In this solution, the support wheel 223 is at least partially located in the water storage area 31 below the drying duct 1. When the support wheel 223 rotates, it plays a role in moving the lint in the water storage area 31 to prevent the lint from accumulating into a ball. It is understandable that the support wheel 223 can be driven by a rotating drive member (such as a motor) to rotate independently, or it can be driven by the filter mesh body 211 to rotate with the filter mesh body 211. There is no limitation here, as long as it does not interfere with the transmission of the filter mesh body 211.

[0074] Figure 7 The structure diagram of one type of support wheel 223 is shown. The support wheel 223 includes two support plates 2231 arranged at intervals, and a plurality of blades 2232 are arranged between the two support plates 2231. The plurality of blades 2232 are distributed in a circumference, and the blades 2232 are used to scrape off the wire scraps on the filter mesh body 211 or to stir the water in the water storage area 31. If the support wheel 223 is fixed, the side of the blade 2232 can scrape off the wire scraps on the moving filter mesh body 211; if the support wheel 223 is rotatable, the blade 2232 can stir the water in the water storage area 31 to disperse the wire scraps in the water and prevent the wire scraps from accumulating into a ball.

[0075] Figure 8 The figure shows a schematic diagram of another structure of the support wheel 223. A plurality of gear teeth 2233 are arranged at intervals along the circumference of the support wheel 223. The gear teeth 2233 are used to scrape off the wire scraps on the filter mesh body 211 or to stir the water in the water storage area 31. If the support wheel 223 is fixed, the edge of the gear teeth 2233 can scrape off the wire scraps on the filter mesh body 211 in motion; if the support wheel 223 is rotatable, the gear teeth 2233 can stir the water in the water storage area 31 to disperse the wire scraps in the water and prevent the wire scraps from accumulating into a ball.

[0076] Optionally, a cleaning member is provided on the inner side and / or the outer side of the filter assembly 21. The cleaning member can be fixed in the drying air duct 1, and the filter assembly 21 can move relative to the cleaning member so that the cleaning member cleans the lint on the filter assembly 21. Exemplarily, the cleaning member includes a scraper and / or a brush. When a paddle 26 is provided on the outer side of the filter body 211, and a cleaning member is provided on the outer side of the filter assembly 21, the cleaning member can be provided as a brush, which is a flexible structure and will not interfere with the transmission of the paddle 26.

[0077] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention.
