It should be noted that the air duct cover 3 provided in the embodiment of the present application can be applied to a machine having a drying function, such as a drying and washing integrated machine, a clothes dryer, and the like, and the clothes dryer 100 is taken as an example for description here. The duct cover 3 is mounted to the dryer 100 to form a duct 7 of the dryer 100. Be equipped with on the wind channel apron 3 and accept chamber 33, accept chamber 33 and be used for holding fragrance agent 5. The air duct cover plate 3 includes a first sidewall 31 forming a receiving cavity 33, an air hole 32 is formed on a side of the first sidewall 31 close to the air duct 7 of the dryer 100, the receiving cavity 33 has an opening 33a, and the opening 33a is disposed on a side far away from the air duct 7 of the dryer 100.

It will be appreciated that as the hot air passes through the duct 7, the fragrance 5 can be heated through the vents 32, causing the fragrance 5 to evaporate into the hot air. Subsequently, the fragrance molecules enter the drum 9 along with the hot air, and the fragrance molecules contact with the laundry and adhere to the laundry, so that the laundry has fragrance thereon. The opening 33a of the receiving cavity 33 is convenient for the user to add the fragrance 5 into the receiving cavity 33 outside the dryer 100.

In the related art, an aromatherapy device is generally separately provided to receive the aromatherapy agent 5, and the aromatherapy device is installed in the hot air passage. However, the parts and the matching between the parts related to the formation of the hot air channel are very complicated, and the aromatherapy device usually has a matching relationship with the related parts forming the hot air channel. The structure of the aromatherapy device is complex, which brings great inconvenience to the installation of the aromatherapy device. In addition, the incense 5 is a volatile consumable and needs to be added periodically, and the complicated structure and assembly and installation relationship of the incense device increase the difficulty of adding the incense 5. The structure of wind channel apron 3 has then been improved to this application embodiment, utilizes accepting chamber 33 of wind channel apron 3 to hold aromatic fumigant 5, and wind channel apron 3 has also played the effect of holding aromatic fumigant 5 when forming wind channel 7, and this application embodiment has realized the multiplexing of wind channel apron 3. Therefore, the washing machine in the embodiment of the application does not need to be additionally and separately provided with the fragrance device, and does not need to be separately installed after relevant parts for forming the hot air channel are installed. The air duct cover plate 3 and other parts are well installed, so that the installation of the aromatherapy device is completed, and the structure and the installation process of the aromatherapy device are simplified.

Referring to fig. 3, 4 and 5 in combination, fig. 3 is a schematic view of the dryer of fig. 1 at another angle, fig. 4 is an assembly view of parts of the dryer of fig. 1, and fig. 5 is a sectional view taken along the direction a-a in fig. 4. The air duct cover plate 3 comprises a main body part 34 and a first side wall 31, the first side wall 31 is connected with the main body part 34, and the first side wall 31 is enclosed to form an accommodating cavity 33. The main body portion 34 of the air duct cover 3 includes a first surface 341 and a second surface 342 disposed oppositely, and the first surface 341 is used for forming the air duct 7 of the clothes dryer 100. The first sidewall 31 is connected to the body portion 34, and the first sidewall 31 may extend toward both sides of the body portion 34 to form the receiving cavity 33, or may extend toward one side of the body portion 34 to form the receiving cavity 33. Preferably, the first sidewall 31 is connected to the first face 341, and the first sidewall 31 extends from the first face 341 in a direction away from the first face 341 to form the receiving cavity 33, that is, the main body 34 is recessed toward the air duct 7 of the dryer 100 to form the receiving cavity 33. At this time, the first accommodating chamber 33 is completely located at one side of the first surface 341 of the main body 34, and the first accommodating chamber 33 can be completely accommodated in the air duct 7 of the dryer 100, so that the incense 5 is completely disposed in the hot air channel. It can be appreciated that this can increase the contact area of the hot air with the fragrance 5, thereby improving the fragrance efficiency of the dryer 100. The design can also make full use of the space in the hot air channel, and avoid the receiving cavity 33 from protruding outwards on the second surface 342, which affects the overall appearance.

Referring to fig. 6, fig. 6 is a schematic structural diagram of an air duct cover plate according to an embodiment of the present disclosure. It can be understood that the first side wall 31 is formed with ventilation holes 32, and the ventilation holes 32 can be oppositely arranged along the flowing direction of the hot air, so that the hot air can enter the accommodating cavity 33 through the ventilation holes 32. In order to further increase the contact area of the hot air with the fragrance 5, the portion of the first sidewall 31 inside the duct 7 may be provided in a grid structure. However, increasing the contact area of the aroma chemical 5 with the hot air at a time also brings about some disadvantages. Illustratively, the fragrance 5 is in a long strip shape, but during the use process, the volume of the fragrance 5 gradually decreases, and the fragrance 5 with smaller volume may fall into a dead angle of the air duct 7 through the air holes 32 or the grid holes on the grid structure, which may interfere with the operation of the related parts, so that the clothes dryer 100 may malfunction during the operation process. Of course, it is also possible for a user to purchase fragrance in granular form directly, which may interfere with the operation of the dryer 100.

Therefore, a membrane (not shown) can be covered on the ventilation holes 32, so that the fragrance 5 with small volume can be prevented from falling into the air duct 7 and interfering the work of the related components. It should be noted that when the clothes dryer 100 is not in operation, the fragrance 5 is still volatilized, which causes a waste of the fragrance 5. Thus, a membrane hole may be provided in the membrane. When the clothes dryer 100 works, the temperature in the clothes drying air duct 7 rises, the pore diameter of the membrane pores is increased after the membrane is heated, and molecules of the fragrance 5 can pass through the membrane pores, so that the fragrance molecules of the fragrance 5 can volatilize into the air duct 7 of the clothes dryer 100 to contact with clothes. When the dryer 100 is not working, the temperature in the air duct 7 of the dryer 100 is lower than the preset temperature, the aperture of the membrane hole is smaller than the diameter of the aroma molecules of the incense 5, and the molecules of the incense 5 can not pass through the membrane hole, thereby avoiding the waste of the incense 5 caused by volatilization. The setting of diaphragm can be guaranteeing that fragrance agent 5 normally volatilizees at dryer 100 during operation, when dryer 100 is out of work, avoids fragrance agent 5 to continue to diffuse to wind channel 7 in, and the setting of diaphragm can avoid dryer 100 waste that fragrance agent 5 volatilizees when non-user state caused effectively.

Referring to fig. 7 and 8, fig. 7 is a sectional view taken along the direction B-B in fig. 6, and fig. 8 is a partially enlarged view of C in fig. 7. The first receiving cavity 33 further includes a box cover 35, the box cover 35 is movably connected to the main body portion 34, and the box cover 35 is disposed at the opening 33a of the receiving cavity 33. In some embodiments, the opening 33a of the receiving cavity 33 is opened on the body 34, and the cover 35 is received in the opening 33a to seal the first receiving cavity 33. It can be understood that the box cover 35 can prevent the fragrance 5 from leaking and volatilizing to the outside of the washing machine, so as to achieve the effect of saving the fragrance 5.

The box cover 35 includes a first connecting portion 351, the first connecting portion 351 is disposed on one side of the box cover 35 close to the main body portion 34, the main body portion 34 is provided with a second connecting portion 343, and the first connecting portion 351 is rotatably connected with the second connecting portion 343. In some specific embodiments, the first connecting portion 351 is a connecting shaft, and the second connecting portion 343 is a connecting hole into which the connecting shaft is inserted, thereby achieving the connection of the box cover 35 and the body portion 34. The shaft and the hole can adopt interference fit and clearance fit. The shaft can be added with rubber-like substances to increase the damping feeling.

The duct cover plate 3 further includes a second side wall 38, the second side wall 38 is disposed between the first side wall 31 and the box cover 35, the second side wall 38 is disposed on a side of the main body 34 away from the second connecting portion 343, one end of the second side wall 38 is connected to the main body 34, and the other end of the second side wall 38 is connected to the first side wall 31 to carry the box cover 35. It is understood that the second side wall 38 may not be provided on the duct cover 3, but the second side wall 38 may be provided to better close the receiving cavity 33 with the box cover 35.

The air duct cover plate 3 further includes a first limiting portion 36 and a second limiting portion 37, a first limiting portion 36 is disposed on one side of the box cover 35 away from the first connecting portion 351, a second limiting portion 37 is disposed on one side of the second side wall 38 facing the box cover 35, and the first limiting portion 36 is connected with the second limiting portion 37, so that the box cover 35 can be connected with the second side wall 38. For example, the first position-limiting part 36 and the second position-limiting part 37 may be magnets, and the magnets on the box cover 35 and the second side wall 38 are magnetically connected, so that the box cover 35 may close the accommodating cavity 33. The user may also open the lid 35 to add the fragrance 5 to the chamber 33. It should be noted that the first limiting portion 36 may also be a buckle (or a snap), and correspondingly, the second limiting portion 37 may be a snap (or a buckle), and the structure of the buckle and the snap can also realize the limitation of the box cover 35 on the second side wall 38. The first and second position-limiting portions 36 and 37 may be made of a sticky substance, which is not limited herein.

It is understood that, in order to further prevent the fragrance 5 from volatilizing out of the dryer 100, the duct cover 3 may further be provided with a sealing member 39, and the sealing member 39 is disposed between the second side wall 38 and the box cover 35. A sealing member 39 may be provided on a surface of the cover plate facing the housing chamber 33, and when the cover plate is covered on the second side wall 38, the sealing member 39 reduces a gap between the cover plate and the second side wall 38, thereby preventing the fragrance 5 from leaking as much as possible.

It should be noted that the aroma fumigant 5 is a volatile consumable product and needs to be added in time. Therefore, the box cover 35 can be made of transparent material, the incense 5 has bright color, and the transparent box cover 35 is convenient for the user to observe the storage amount of the incense 5 in the first accommodating cavity in time.

In order to facilitate the user to open the cover plate to add the fragrant fumigant 5, a handheld structure 3a can be arranged on the cover plate, and the handheld structure 3a is arranged on one surface of the box cover 35 deviating from the first accommodating cavity 33. Illustratively, the holding structure 3a may be a boss, a groove, a button, or the like, without limitation.

The embodiment of the application also provides a clothes dryer, please refer to fig. 1 and fig. 3. In the embodiment of the present application, the clothes dryer 100 is merely taken as an example, and the clothes drying and washing machine having a clothes drying function may be used. The clothes drying and washing machine can be a drum washing machine, a parallel-bar washing machine or a full-automatic impeller washing machine.

It should be noted that the dryer 100 includes a heater, a condenser, and a blower, and the related parts cooperate to form the air duct 7. The condenser is used for condensing water vapor in the air into water, and the condensed water is discharged out of the dryer 100 through other components. The heater is used for heating air, and hot air is conveyed into the roller 9 through the air duct 7 and the fan. When the dryer 100 performs a drying operation, the air inlet draws air into the dryer 100, and the condenser condenses water vapor carried in the air into water, i.e., the condenser "dehumidifies" the air entering the dryer 100. The air dehumidified by the condenser is heated by the heater, and the dry hot air enters the washing drum to dry the clothes under the action of the fan and the air duct 7. The hot air dries the laundry in the drum 9. The dry hot air heats the laundry and carries away the water vapor evaporated from the laundry. Subsequently, the air carrying a large amount of moisture passes through a condenser, which liquefies the moisture in the air by cooling at a low temperature. The dehumidified air enters the heater to be heated. The hot and dry air is repeatedly supplied into the drum 9, thereby drying the laundry.

The clothes dryer 100 in the embodiment of the present application includes a rear plate 1 and the air duct cover plate 3 as described above, the air duct cover plate 3 is disposed opposite to the rear plate 1, an air duct 7 is formed between the air duct cover plate 3 and the rear plate 1, and the air holes 32 are communicated with the air duct 7. It will be appreciated that, during operation of the dryer 100, the fragrance 5 will evaporate into the air duct 7. The aroma molecules can be infused into the dry hot air through the air vents 32. The dry hot air with the fragrant substance is delivered into the drum 9 to attach fragrant smell to the laundry in the drum 9.

The dryer 100 may have a sterilization function. In some specific embodiments, an ultraviolet light source (not shown) may be disposed within the drum 9 of the dryer 100. For example, the ultraviolet light source may be designed to be annular and disposed at an open position of the drum 9, so that the laundry in the drum 9 can be irradiated with the ultraviolet light in all directions. Further, in order to simplify the structure related to the sterilization function, the ultraviolet light source may be an ultraviolet light pipe or an ultraviolet light patch lamp. When the clothes dryer 100 is in operation, the clothes dryer 100 automatically turns on the ultraviolet light source to perform ultraviolet sterilization on the clothes in the drum 9, so that the clothes are deeply cleaned. The clothes dryer 100 with the aromatherapy and sterilization functions can provide a healthier and more comfortable clothes drying body feeling for users, and meets the requirements of high-quality life of modern society.

It should be noted that, in the operation of the clothes dryer 100, the clothes tumble with the rotation of the drum 9, and clothes lint and lint are generated in the drum, and the lint and lint enter the air duct 7 along with the flow of air. The hot air used for drying the laundry carries a large amount of water vapor, and the lint is easily attached to the relevant parts forming the air duct 7, particularly the condenser and the heater, in a humid environment. Over time, the accumulated flock blocks the air duct 7, so that the drying effect is poor and energy is wasted. The decay of the flock also causes problems of peculiar smell, bacterial pollution and the like. Therefore, the dryer 100 is also required to have a lint filtering function.

In order to prevent the thread scraps from entering the air duct 7, the hot air is circulated through a filter screen for filtering the impurities in the air flow. The hot air will continuously pass through the clothes and then blow to the filter screen, and the hot air is filtered and then enters the air duct 7. The common method is that the filter screen is fixed on the plastic part, the plastic part is placed at the opening of the air duct 7, and the filter screen is made into a structure which is convenient to disassemble, so that the filter screen is convenient to disassemble and clean. After a certain time, the filter screen is detached by a user, and the thread scraps and the hair scraps are cleaned. In order to facilitate the disassembly and assembly of users, a handle can be arranged on the filter screen.

The existing mode also has some defects, and some users do not have the habit of cleaning the filter screen regularly, so the flock on the filter screen cannot be cleaned in time. When the lint is excessively accumulated on the filter, the filter may be blocked, resulting in poor ventilation and insufficient heat exchange, and thus the load of the dryer 100 becomes large. In this state, the dryer 100 may be operated for a long time to cause a certain safety hazard to the components of the whole dryer. Therefore, the filter screen lint can be cleaned by using water, and the clothes dryer 100 enters a self-cleaning mode after finishing the drying process. In the self-cleaning process, the lint on the filter screen may be washed away by water, and then the water with the lint may be discharged out of the dryer 100 through related components.

In the foregoing embodiments, the descriptions of the respective embodiments have respective emphasis, and for parts that are not described in detail in a certain embodiment, reference may be made to related descriptions of other embodiments.

The air duct cover plate and the clothes dryer provided by the embodiment of the application are described in detail, a specific example is applied to explain the principle and the implementation mode of the application, and the description of the embodiment is only used for helping to understand the method and the core idea of the application; meanwhile, for those skilled in the art, according to the idea of the present application, there may be variations in the specific embodiments and the application scope, and in summary, the content of the present specification should not be construed as a limitation to the present application.
