[0050] The following describes this embodiment in detail with reference to the accompanying drawings. Unless otherwise specified, the following embodiments and examples can be combined with each other.

[0051] Example 1

[0052] This embodiment proposes an aromatherapy box, such as Figures 1-8 As shown, the aromatherapy box includes an outer box 1 and an inner box 2, which are inserted into and fitted together with the outer box 1. Wherein:

[0053] The outer box 1 includes a base 11 and an outer box body 12. The outer box body 12 is located on the base 11. The outer box body 12 has a first accommodating cavity 123. The base 11 and the outer box body 12 have mounting holes 111 at corresponding positions. The mounting holes 111 communicate with the first accommodating cavity 123. The outer box body 12 includes a closed area and a breathable area.

[0054] The structure of base 11 is not limited; it can be adapted to other components of the dryer within the aromatherapy box. In one example, such as... Figure 2 As shown, when the aroma diffuser box is installed in the front air duct 5 of the dryer, the base 11 is a plate-like structure adapted to the front air duct wall 51. In other possible implementations, such as... Figure 10 As shown, when the aromatherapy box is installed in the filter box 41 of the dryer, the base 11 is a mesh structure adapted to the filter cover 42 of the filter box 41.

[0055] The inner box 2 includes an inner box body 21, which is housed in a first receiving cavity 123 via a mounting hole 111. The inner box body 21 has a second receiving cavity 215 for holding aromatherapy substances. The wall of the inner box body 21 has vent holes 212 through which the aromatherapy substances can be released. The inner box body 21 can rotate within the first receiving cavity 123 to adjust the communication area between the vent holes 212 and the ventilation area.

[0056] This embodiment, by configuring the outer box 12 into a structure including a base 11 and the outer box 12, allows the aromatherapy box to be combined with other components of the dryer via the base. For example, when the aromatherapy box is located in the front air duct 5 of the dryer, the base 11 can be combined with the front air duct 5. When the aromatherapy component is located in the filter assembly 4 of the dryer, the base 11 can be combined with the filter cover 42 of the filter assembly 4, thereby simplifying the aromatherapy box structure, reducing the number of parts, and lowering production costs. Furthermore, users can adjust the aromatherapy concentration at any time according to their needs; the operation is simple and convenient, requiring no disassembly of any parts, and users can select any fragrance level from unscented to strongly scented.

[0057] In one alternative implementation, such as Figure 4 As shown, the outer casing 12 includes a baffle. The baffle is arranged along the circumferential direction of the mounting hole 111 to enclose a first receiving cavity 123, and the baffle forms a closed area. The area of ​​the mounting hole 111 not enclosed by the baffle in the circumferential direction forms a ventilated area. For example, as... Figure 4As shown, the baffle is arc-shaped, which reduces the volume of the outer box 12 while ensuring that the inner box 21 can rotate within the outer box 12, thus reducing the space occupied by the aromatherapy box.

[0058] Vent hole 212 is provided on the side wall of inner box 21. When inner box 21 is rotated to the first preset position, the baffle can completely close vent hole 212. When inner box 21 is rotated to the second preset position, vent hole 212 is completely exposed in the venting area. For example, the baffle encloses half of the area in the circumferential direction of the mounting opening to form a closed area, and the other half of the area in the circumferential direction of the mounting hole 111 is the venting area.

[0059] This embodiment simplifies the structure of the outer box 12 by using a baffle to form the outer box 12, and can fully open and close the vent 212 of the inner box 21 when the inner box 21 rotates, so that users can adjust the fragrance level of the aromatherapy substance from unscented to strong fragrance according to their needs.

[0060] The structure of the vent 212 is not limited; it can be a grid structure formed by multiple round holes or multiple strip holes arranged in the depth direction of the inner box 21.

[0061] In other possible implementations, the outer box 12 is a cylindrical structure, and ventilation holes 212 are also provided on the side wall of the cylindrical structure to form a ventilation area. The area on the side wall of the cylindrical structure where ventilation holes 212 are not formed is a closed area.

[0062] In one alternative implementation, such as Figure 4 As shown, the baffle includes a first end and a second end located in the circumferential direction of the mounting hole 111. The first end is provided with a first baffle 121, and the second end is provided with a second baffle 122. The inner box 21 is provided with a first limiting baffle 211. The first preset position is when the inner box 21 rotates to a position where it contacts the first baffle 121, and the second preset position is when the inner box 21 rotates to a position where it contacts the second baffle 122. In this embodiment, by setting the first baffle 121, the second baffle 122, and the first limiting baffle 211, the rotation position of the inner box 21 can be limited, so that the user can accurately rotate to the first position where the vent hole 212 is completely closed and the second position where the vent hole 212 is completely opened.

[0063] In one alternative implementation, such as Figure 3 , Figure 4 and Figure 6As shown, the inner wall of the mounting hole 111 is provided with a guide groove 112. Both the guide groove 112 and the first limiting rib 211 are arranged along the depth direction of the inner box 21. During the assembly of the inner box 2 and the outer box 1, the first limiting rib 211 cooperates with the guide groove 112, and when the inner box 2 is assembled in place, the first limiting rib 211 separates from the guide groove 112, so that the inner box 21 can rotate within the first receiving cavity 123.

[0064] Specifically, in the depth direction of the inner box 2, the length of the inner box 2 is greater than the length of the first limiting rib 211. During the assembly process of the inner box 2 and the outer box 1, the inner box 2 is inserted into the outer box 1 along the guide groove 112 through the first limiting rib 211. When the first limiting rib 211 is completely submerged in the outer box 1 and disengaged from the guide groove 112, the inner box 2 and the outer box 1 are assembled. At this time, the inner box 2 can rotate relative to the outer box 1.

[0065] In this embodiment, the guide groove 112 and guide wall can limit the inner box body 21 during the assembly of the inner box 2 and the outer box 1, preventing the inner box 2 from shifting in the circumferential direction of the mounting opening during the assembly of the inner box 2 and the outer box 1. At the same time, after the inner box 2 is assembled in place, it does not affect the rotation of the inner box body 21 in the first accommodating cavity 123.

[0066] In one optional implementation, the inner box 2 further includes a lid 22, which cooperates with the inner box body 21 to open and close the opening of the inner box body 21. Rotation of the lid 22 causes the inner box body 21 to rotate, allowing the user to adjust the communication area between the ventilation holes 212 of the inner box body 21 and the ventilation area of ​​the outer box body 12. In one example, such as... Figure 4 and Figure 8 As shown, the inner box 21 has a limiting groove 213 on the outer wall near the opening. The limiting groove 213 extends along the depth direction of the inner box 21. The inner wall of the lid 22 has a second limiting rib 221. The second limiting rib 221 and the limiting groove 213 limit each other. In this way, the lid 22 can only be assembled with the inner box 21 in a specific direction, and the installation position of the lid 22 can be clearly defined.

[0067] In other possible ways, the inner box 21 and the lid 22 can also be connected by threaded connection, snap-fit ​​or connector connection, which is not specifically limited here.

[0068] In one alternative implementation, such as Figure 8 and Figure 10 As shown, the lid 22 includes a marking portion 222, which can rotate with the lid 22 to a target position to indicate the communication state and / or communication area between the vent 212 and the vent area. The type of marking portion 222 is not limited; it can be text or a reduced-width line marking. (See reference...) Figure 8The indicated location is, for example, directly above or below the outer casing 12. In this embodiment, by providing a label 222, the user can clearly identify the current aromatherapy concentration.

[0069] And / or, such as Figure 10 As shown, the outer end face of the lid 22 is provided with a knob 223 to reduce the difficulty for the user to rotate the lid 22.

[0070] In one optional implementation, the base 11 is provided with a limiting ring 113, which surrounds the outer periphery of the mounting hole 111. The side wall of the inner box 21 is provided with a sealing ring groove 214, and a sealing ring 3 is provided within the sealing ring groove 214. When the inner box 2 and outer box 1 are assembled, the limiting ring 113 and the sealing ring 3 are in an interference fit. This embodiment, by interfering with the sealing ring 3 and the limiting ring 113, prevents airflow from escaping from the front air duct 5 when the aromatherapy box is installed in the front air duct 5.

[0071] Example 2

[0072] This embodiment also proposes an air duct assembly, such as Figure 11 As shown, the air duct assembly includes a front air duct 5 and an aromatherapy box as described in Embodiment 1. The front air duct 5 includes a front air duct wall 51, and the outer box 1 of the aromatherapy box is disposed on the front air duct wall 51. The base 11 of the aromatherapy box can be set independently of the front air duct wall 51 and connected to the front air duct wall 51 by means of snap-fit, plug-in, connector, adhesive or welding, or the base 11 of the aromatherapy box is integrally formed with the front air duct wall 51, and the inner box 21 can extend into the interior of the front air duct 5 through the mounting hole 111. The aroma released by the aromatherapy substance directly enters the front air duct 5 and enters the dryer drum with the airflow in the front air duct 5.

[0073] The air duct assembly in this embodiment combines the front air duct 5 with the aromatherapy box, simplifying the assembly between the aromatherapy box and the air duct. It has a simple structure, is easy to disassemble and adjust, and allows users to select any fragrance level from unscented to strongly scented.

[0074] Example 3

[0075] This embodiment provides a filter assembly 4, such as... Figure 9 and Figure 10 As shown, the filter assembly 4 includes a filter box 41, a filter cover 42 for sealing the filter box 41, and an aromatherapy box as described in Embodiment 1. The filter cover 42 has multiple filter holes 421, and the outer box 1 of the aromatherapy box is disposed on the filter cover 42. The base 11 of the aromatherapy box can be set independently of the filter cover 42 and connected to the filter cover 42 by means of snap-fit, plug-in, connector connection, or adhesive bonding, or the base 11 of the aromatherapy box is integrally formed with the filter cover 42, and the inner box body 21 can extend into the filter box 41 through the mounting hole 111.

[0076] In this embodiment, the filter assembly 4 combines the filter cover 42 with the aromatherapy box, simplifying the assembly between the aromatherapy box and the filter cover 42. The structure is simple, easy to disassemble and adjust, and the user can select any fragrance level from no fragrance to strong fragrance.

[0077] Example 4

[0078] This embodiment also proposes a clothes dryer, such as... Figure 11 As shown, the dryer includes a housing and the air duct assembly proposed in Embodiment 2. The housing includes a front shell 6, which has a mating hole that corresponds to the mounting hole 111. The inner box 21 can extend into the front air duct 5 through the mating hole and the mounting hole 111. Furthermore, the mating hole is positioned to cover the dryer door. That is, when the dryer door is closed and the clothes inlet is closed, the aromatherapy box is also covered by the door. When adjusting the aromatherapy concentration, the user can open the door and rotate the aromatherapy box to adjust the concentration. The structure is simple and the operation is convenient. When changing the aromatherapy, simply rotate the aromatherapy box to a specific position, lift it upwards, and open the aromatherapy lid.

[0079] The dryer also includes a drying drum 8 and a front support frame. The drying drum 8 is rotatably mounted inside the housing. The front support frame is located on the front side of the drying drum 8 and forms a clothing inlet. The clothing inlet is corresponding to the opening of the drying drum 8. The lower part of the inner wall of the clothing inlet has a mounting groove, in which a filter assembly 4 is installed. The filter assembly 4 is connected to the front air duct 5, and the mounting groove forms the air outlet of the drying drum 8. The evaporator assembly 7 is located below the drying drum 8. One end of the front air duct 5 is connected to the air outlet of the drying drum 8, and the other end is connected to the air inlet of the evaporator of the evaporator assembly 7. The air outlet of the condenser of the evaporator assembly 7 is connected to the air inlet of the rear air duct 9, and the air outlet of the rear air duct 9 is connected to the air inlet of the drying drum 8.

[0080] In this embodiment, the dryer combines the aroma box with the front air duct 5, and the outer box 1 with the front air duct wall 51, which simplifies the aroma box structure, reduces production costs, and allows the fragrance released by the aroma substances to directly enter the front air duct 5 and enter the drying drum 8 with the airflow, thereby improving the aroma effect on the clothes.

[0081] Example 5
