[0002] The rapid development of technologies related to laundry treatment equipment has brought great convenience to users. Most families need to purchase multiple laundry treatment equipment. At this time, the user's recognition of laundry treatment equipment directly determines the user's purchase target for replacement laundry treatment equipment.

[0003] Current washing machines rely solely on the rotation of the washing tub to air dry, dry, or remove odors, making it difficult for the air inside the tub to exchange with the outside air. Alternatively, fans are used to blow air into the tub, significantly increasing costs and reducing reliability.

[0004] Chinese patent application number 201811325764.2 discloses a washing machine with a ventilation device and a barrel drying control method thereof. The washing machine includes a housing and an openable and closable upper cover. The upper cover is provided with at least one ventilation device that allows the washing barrel of the washing machine to communicate with the outside world. The ventilation device includes an exhaust fan and ventilation grilles respectively arranged on the upper cover. By arranging the ventilation device on the upper cover, it is beneficial to dry the washing barrel and avoid the growth of bacteria in the washing barrel and the secondary contamination problem caused.

[0005] The above-mentioned washing machine blows air into the washing tub by providing a ventilation device to achieve an air-drying process for the washing tub. However, this air-drying method has a relatively slow drying speed and still has the problems of low air-drying efficiency and high manufacturing cost.

[0006] In view of this, the present invention is proposed. Summary of the Invention

[0040] Currently, washing machines rely solely on the rotation of the washing tub to perform air drying, drying, and odor removal, making it difficult for the air inside the tub to exchange with the outside air. Alternatively, fans are used to blow air into the tub, significantly increasing costs and reducing reliability.

[0041] Example 1

[0042] To solve the above problems, Figures 1 to 5 As shown, this embodiment provides an auxiliary air inlet mechanism for a washing machine, the washing machine comprising a washing tub 1 and a balancing ring 2, the balancing ring 2 being arranged above the washing tub 1 and comprising:

[0043] The air guide cover 3 is provided on one side of the balance ring 2 and is rotatably connected to the balance ring 2;

[0044] The air guide cover 3 rotates around one end thereof, and the extension direction of the air guide cover 3 is consistent with the dehydration rotation direction of the washing tub 1 .

[0045] In this embodiment, the washing machine includes a washing tub 1 and an outer tub 4. The washing tub 1 is disposed within the outer tub 4 and is used to hold laundry. The washing machine also includes a balancing ring 2 disposed above the washing tub 1. The outer tub 4 includes an outer tub cover 41 disposed above the outer tub 4.

[0046] In this embodiment, the auxiliary air inlet mechanism includes an air guide cover 3, which is arranged on the balance ring 2. The air guide cover 3 is used to promote the rapid flow of air in the washing tub 1, increase the air exchange frequency in the washing tub 1, and speed up the drying speed of the washing tub 1.

[0047] Furthermore, a portion of the air guide cover 3 is disposed on the side of the balance ring 2 close to the opening 34 of the washing tub 1, and another portion of the air guide cover 3 is disposed on the side of the balance ring 2 facing the cover of the outer tub 4. The extended shape of the air guide cover 3 is consistent with the shape of the balance ring 2.

[0048] In a further solution of this embodiment, the air guide cover 3 is rotatably connected to the balance ring 2 , that is, the air guide cover 3 can be rotated around one end thereof to open the air guide cover 3 , so that an opening 34 is formed between the air guide cover 3 and the balance ring 2 .

[0049] Furthermore, the extension direction of the air guide cover 3 on the balance ring 2 is consistent with the dehydration rotation direction of the washing tub 1, which is conducive to accelerating the blowing speed in the washing tub 1, accelerating the exchange of air in the washing tub 1 with the outside, and improving the air drying speed.

[0050] In a further embodiment of the present invention, the air guide cover 3 is extended to form an arc shape. As can be seen, the arc-shaped configuration of the air guide cover 3 effectively increases the wind force generated when the washing tub rotates, thereby increasing the speed of blowing air into the washing tub 1, thereby forming a negative pressure at the balance ring 2, promoting rapid exchange of air between the washing tub 1 and the outside, and further accelerating the drying speed within the washing tub 1.

[0051] Example 2

[0052] This embodiment is a further description of the above embodiment 1.

[0053] like Figures 3 and 4 As shown, in this embodiment, the balancing ring 2 includes a positioning hole 21 , and the positioning hole 21 is provided on a side surface of the balancing ring 2 close to the washing tub 1 .

[0054] Specifically, the balance ring 2 includes a positioning hole 21, which is provided on a side surface of the balance ring 2 close to the opening 34 of the washing tub 1. The positioning hole 21 is used to fix the air guide cover 3 and realize the rotational connection between the air guide cover 3 and the balance ring 2.

[0055] In this embodiment, a first positioning post 31 is provided on the air guide cover 3 . The first positioning post 31 is disposed at a position corresponding to the positioning hole 21 , and the positioning post is inserted into the positioning hole 21 .

[0056] Specifically, the air guide cover 3 includes a first positioning post 31, which is disposed at a position on the air guide cover 3 corresponding to the first positioning hole 21. The first positioning post 31 is provided to protrude and extend. The first positioning post 31 is inserted into the first positioning hole 21 and rotates, thereby achieving a rotational connection between the air guide cover 3 and the balance ring 2, and enabling the air guide cover 3 to be opened so that its extension direction is consistent with the dehydration rotation direction of the washing tub 1.

[0057] In a further solution of this embodiment, the balancing ring 2 includes a positioning rib 22 . The positioning rib 22 is provided above the positioning hole 21 and protrudes from one side of the balancing ring 2 along its extension direction.

[0058] Specifically, the balance ring 2 includes a positioning rib 22 , which is provided on one side of the balance ring 2 near the first positioning hole 21 and extends a certain length from the balance ring 2 toward the other side. The positioning rib 22 is used to position and fix the air guide cover 3 .

[0059] In a further solution of this embodiment, a portion of the air guide cover 3 corresponding to the positioning rib 22 is recessed inward to form a groove 32 , and the positioning rib 22 is clamped in the groove 32 .

[0060] Specifically, a groove 32 is provided on the air guide cover 3 , and the groove 32 is arranged at a position corresponding to the air guide cover 3 and the positioning rib 22 . The corresponding areas of the air guide cover 3 and the positioning rib 22 are recessed inward to form the groove 32 .

[0061] Furthermore, the positioning rib 22 is clamped in the groove 32 to fix and limit the air guide cover 3, prevent the air guide cover 3 from shaking when the washing tub 1 rotates, avoid the air guide cover 3 from falling off, and improve the connection stability between the air guide cover 3 and the balance ring 2.

[0062] In a further solution of this embodiment, the balancing ring 2 further includes a slide 23 . The slide 23 is provided on a side of the balancing ring 2 away from the washing tub 1 and is tilted along the extension direction of the balancing ring 2 .

[0063] Specifically, the balance ring 2 further includes a slide 23, which is provided on the side of the balance ring 2 facing the cover of the outer barrel 4 and is provided above the first positioning hole 21. The slide 23 is used to realize the open state of the air guide cover 3 and to limit the opening angle of the air guide cover 3.

[0064] Furthermore, the slideway 23 extends along the circumferential direction of the axis of the balance ring 2 and is inclined downwardly from the balance ring 2. The extension length of the slideway 23 determines the opening angle of the air guide cover 3, which in turn affects the speed at which the air guide cover 3 exchanges air between the washing tub 1 and the outside.

[0065] In a further solution of this embodiment, the air guide cover 3 includes a second positioning column 33 . The second positioning column 33 is embedded in the slideway 23 and slides along the extension direction of the slideway 23 .

[0066] Specifically, the air guide cover 3 further includes a second positioning post 33 . The second positioning post 33 is disposed at a position corresponding to the slideway 23 . The second positioning post 33 is disposed above the first positioning post 31 .

[0067] Furthermore, the second positioning column 33 is embedded in the slide 23, and the second positioning column 33 can slide in the slide 23, thereby realizing the rotation of the air guide cover 3 to open the air guide cover 3, adjust the opening angle of the air guide cover 3, accelerate the air exchange in the washing tub 1, and improve the drying efficiency.

[0068] In a further solution of this embodiment, the air guide cover 3 rotates around one end of the first positioning column 31, and an opening 34 is formed between the air guide cover 3 and the balance ring 2. The direction of the opening 34 is opposite to the dehydration rotation direction of the washing tub 1.

[0069] Specifically, the first positioning post 31 is inserted into the positioning hole 21 and rotates, while the second positioning post 33 is embedded in the slide 23 and slides, thereby realizing the rotation and opening process of the air guide cover 3. When the air guide cover 3 is opened, an opening 34 is formed between the air guide cover 3 and the balance ring 2. The direction of the opening 34 is opposite to the direction of the spin cycle of the washing tub 1. It can also be understood that the extension direction of the air guide cover 3 is consistent with the spin cycle of the washing tub 1, forming a negative pressure at the balance ring 2, thereby facilitating the exchange of air between the washing tub 1 and the outside.

[0072] like Figures 3 to 5 As shown, in this embodiment, the gimbal 2 includes a first positioning slot 24 and a second positioning slot 25 , which are respectively arranged on a side of the gimbal 2 away from the positioning hole 21 , and are arranged on different sides of the gimbal 2 .

[0073] Specifically, the gimbal 2 further includes a first positioning slot 24, which is provided on a side of the gimbal 2 facing the cover of the outer tub 4. The first positioning slot 24 and the slideway 23 are respectively provided on both sides of the gimbal 2. The first positioning slot 24 is used to secure the air guide cover 3 when it is closed.

[0074] More specifically, the balancing ring 2 further includes a second positioning slot 25, which is provided on a side of the balancing ring 2 close to the opening 34 of the washing tub 1 and below the first positioning slot 24.

[0076] Specifically, the air guide cover 3 includes a first positioning protrusion 35, which is arranged at a position corresponding to the air guide cover 3 and the first positioning slot 24. The first positioning protrusion 35 is clamped in the first positioning slot 24 to fix the air guide cover 3 and the balance ring 2, thereby achieving the closed state of the air guide cover 3.

[0077] More specifically, the air guide cover 3 includes a second positioning protrusion 36, which is arranged below the first positioning protrusion 35. The first positioning protrusion 35 is clamped in the first positioning slot 24 to achieve a closed state between the air guide cover 3 and the balance ring 2, further improving the fixing tightness between the two.

[0078] In a further solution of this embodiment, a handle 37 is provided on the outer side of the air guide cover 3 , and the air guide cover 3 is opened by pulling the handle 37 .

[0079] Specifically, the air guide cover 3 includes a hand buckle 37, which is arranged on the outside of the air guide cover 3 and is used to pull the hand buckle 37 outward to open the air guide cover 3, so that an opening 34 is formed between the air guide cover 3 and the balance ring 2.
