[0061] As Figures 1 to 10 shown, according to an embodiment of the present application, a top cover assembly 20 for a top-opening laundry treatment device 100 is provided, and the top cover assembly 20 includes a gas passage 24, a first air hole 221, and a second air hole 2251.

[0062] Wherein, the first air hole 221 and the second air hole 2251 are respectively in communication with the gas passage 24. The first air hole 221 is used for communicating with the laundry treatment chamber 111 of the top-opening laundry treatment device 100, and the second air hole 2251 is used for communicating with the outside.

[0063] When the top cover assembly 20 is in use, the laundry processing chamber 111 of the top-opening laundry processing device 100 is connected to the outside through the first air hole 221, the gas passage 24, and the second air hole 2251. When processing laundry, the first air hole 221, the gas passage 24, and the second air hole 2251 are used to connect the laundry processing chamber 111 to the outside, so that the air pressure in the laundry processing chamber 111 is balanced (the gas passage 24 is respectively connected to the first air hole 221 and the second air hole 2251. When the top cover assembly 20 is used for the top-opening laundry processing device 100, when the air pressure in the laundry processing chamber 111 is higher than the external gas pressure, the gas in the laundry processing chamber 111 is discharged to the outside through the first air hole 221, the gas passage 24, and the second air hole 2251, so as to reduce the air pressure in the laundry processing chamber 111, so that the air pressure in the laundry processing chamber 111 is consistent with the external air pressure. When the air pressure in the laundry processing chamber 111 is lower than the external gas pressure, the external gas enters the laundry processing chamber 111 through the second air hole 2251, the gas passage 24, and the first air hole 221, so as to increase the air pressure in the laundry processing chamber 111, so that the air pressure in the laundry processing chamber 111 is consistent with the external air pressure). The vibration noise generated by the pressure difference during the use of the top-opening laundry processing device 100 is reduced, and the user experience is improved.

[0064] In addition, in the present application, when the top cover assembly 20 is used for the top-opening laundry processing device 100, the top cover is installed on the top of the top-opening laundry processing device 100, and the first air hole 221, the gas passage 24, and the second air hole 2251 are arranged on the top cover, so that the exhaust structure formed by the first air hole 221, the gas passage 24, and the second air hole 2251 has a sufficient distance from the washing water and foam in the laundry processing chamber 111, so that it is difficult for the washing water and foam to reach the position of the exhaust structure during the laundry processing process, thereby effectively reducing the situation of the washing water and foam overflowing from the exhaust structure, and effectively improving the user experience.

[0065] In addition, the first air hole 221, the gas passage 24, and the second air hole 2251 are arranged on the top cover assembly 20, so that the exhaust position is above the laundry processing chamber 111, thus conforming to the flow direction of the air flow, facilitating the effective discharge of the air flow, and improving the discharge efficiency of the air flow.

[0066] It should be noted that in the present application, the gas passage 24 can be entirely arranged inside the top cover assembly 20, entirely arranged outside the top cover assembly 20, or partially arranged inside the top cover assembly 20 and the other part arranged outside the top cover assembly 20.

[0067] In some embodiments of the present application, such as Figures 5 to 7As shown, in the top cover assembly 20, there is a filter element 23. The filter element 23 is disposed inside the gas passage 24 of the top cover assembly 20 and divides the gas passage 24 into two parts. One part is on one side of the filter element 23, and the other part is on the other side of the filter element 23. The two parts are only connected through the filter element 23. One of the first air hole 221 and the second air hole 2251 is connected to one of the parts, and the other of the first air hole 221 and the second air hole 2251 is connected to the other of the parts. The filter element 23 filters the fluid passing through the gas passage 24 and is configured to allow only gas to pass through.

[0068] Specifically, when the top cover assembly 20 is used for a top-opening type laundry treating device 100, the top cover assembly 20 is installed on the top of the top-opening type laundry treating device 100 and is used to open or close the top opening of the laundry treating chamber 111. The laundry treating chamber 111 is connected to the outside through the first air hole 221, the gas passage 24, and the second air hole 2251. When the top-opening type laundry treating device 100 treats laundry, if the washing water and foam in the laundry treating chamber 111 overflow from the first air hole 221, when the overflowed washing water and foam reach the filter element 23, the filter element 23 intercepts the overflowed washing water and foam, so that the washing water and foam cannot continue to flow along the gas passage 24 and overflow.

[0069] It should be understood that the filter element 23 can absorb or intercept the washing water and foam overflowing from the first air hole 221, so that the washing water and foam cannot pass through the filter element 23, thereby reducing the situation of washing water and foam overflowing.

[0070] It should be noted that the filter element 23 is disposed in the gas passage 24, and the cooperation mode between the filter element 23 and the gas passage 24 can be set as a detachable mode. The filter element 23 is disposed in the gas passage 24 in a detachable manner. When the filtering effect of the filter element 23 deteriorates, the filter element 23 can be replaced by disassembling the filter element 23, so that the filter element 23 can maintain good filtering performance.

[0071] In some embodiments of the present application, as Figures 5 to 7 shown, the gas passage 24 is disposed inside the top cover assembly 20, the filter element 23 is disposed in the gas passage 24, and the first passage portion 2261 and the second passage portion 242 are separated in the gas passage 24. The first passage portion 2261 and the second passage portion 242 are disposed on opposite sides of the filter element 23. The first passage portion 2261 is connected to the first air hole 221, and the second passage portion 242 is connected to the second air hole 2251.

[0072] Specifically, along the circumferential direction of the top opening of the clothing treatment chamber 111 of the top-opening clothing treatment device 100, when the top cover assembly 20 is used for the clothing treatment device 100, the top cover assembly 20 can close the top opening of the clothing treatment chamber 111. The top opening of the clothing treatment chamber 111 has a projection on the top cover assembly 20, and the first air hole 221 is opened within the range of this projection. The gas channel 24 can be a straight channel structure or a bent channel structure.

[0073] When the gas channel 24 is a straight channel structure (the straight channel structure can be arranged along the vertical direction or at an acute angle to the vertical direction), the filter element is arranged inside the straight channel structure and divides the straight channel structure into a first channel portion and a second channel portion. The first air hole is communicated with the first channel portion, and the second air hole is communicated with the second channel portion.

[0074] The following takes the gas channel 24 as a bent channel structure as an example for specific description:

[0075] The extending direction of the first channel portion 2261 is the same as the vertical direction or is arranged at an acute angle to the vertical direction (the acute angle can be 10°, 20°, 30°, 40°, 50°, 60°, 70° or 80°, etc.). The second channel portion 242 is connected to the first channel portion 2261 at an angle (the angle can be 90°, 120° or 150°, etc.).

[0076] By setting the first air hole 221, it is convenient for the clothing treatment chamber 111 to communicate with the first air hole 221. In addition, by setting the extending direction of the first channel portion 2261, when the washing water and foam enter the inside of the first channel portion 2261 through the first air hole 221, under the action of gravity, the washing water and bubbles can fall back into the inside of the clothing treatment chamber 111, further reducing the occurrence of the situation where the washing water and foam overflow.

[0077] In addition, by setting the filter element 23, the first channel portion 2261 and the second channel portion 242 are separated by the filter element 23. The filter element 23 filters the washing water and foam overflowing from the first channel portion 2261, realizing the absorption and interception of the washing water and foam, so as to reduce the possibility of the washing water and foam entering the second channel portion 242 and further reducing the occurrence of the situation where the washing water and foam overflow.

[0078] In some embodiments of the present application, the filter member 23 is a sponge. The first channel portion 2261 and the second channel portion 242 are separated by the sponge. When washing water and foam appear in the first channel portion 2261, the sponge can absorb the washing water and the foam, thereby reducing the entry of the washing water and the foam into the second channel portion 242, and further reducing the occurrence of the overflow of the washing water and the foam. The structure of the sponge is simple and the manufacturing cost is low, which can effectively reduce the manufacturing cost.

[0079] In some embodiments of the present application, the filter member 23 is a non-woven fabric. The non-woven fabric forms a non-woven fabric filter module. The first channel portion 2261 and the second channel portion 242 are separated by the non-woven fabric filter module. When washing water and foam appear in the first channel portion 2261, the non-woven fabric filter module can absorb the washing water and the foam, thereby reducing the entry of the washing water and the foam into the second channel portion 242, and further reducing the occurrence of the overflow of the washing water and the foam. The structure of the sponge is simple and the manufacturing cost is low, which can effectively reduce the manufacturing cost.

[0080] In some embodiments of the present application, as Figures 5 to 7 shown, the gas channel 24 includes a first channel portion 2261, a second channel portion 242, and a third channel portion 243. Among them, the first channel portion 2261 and the second channel portion 242 are spaced apart by the filter member 23, the second channel portion 242 and the third channel portion 243 are connected and arranged in communication, the first air hole 221 is connected and communicated with the first channel portion 2261, and the second air hole 2251 is connected and communicated with the second channel portion 242.

[0081] Specifically, when the top cover assembly 20 is used for a top-opening type laundry treating apparatus 100, the top cover assembly 20 is installed on the top of the top-opening type laundry treating apparatus 100 and is used to open or close the top opening of the laundry treating chamber 111. When the top-opening type laundry treating apparatus 100 is operating, when the air pressure in the laundry treating chamber 111 is higher than the external gas pressure, the gas in the laundry treating chamber 111 is discharged to the outside through the first air hole 221, the first channel portion 2261, the filter member 23, the second channel portion 242, the third channel portion 243, and the second air hole 2251, so as to reduce the air pressure in the laundry treating chamber 111, thereby making the air pressure in the laundry treating chamber 111 consistent with the external air pressure. When the air pressure in the laundry treating chamber 111 is lower than the external gas pressure, the external gas enters the laundry treating chamber 111 through the second air hole 2251, the third channel portion 243, the second channel portion 242, the filter member 23, the first channel portion 2261, and the first air hole 221, so as to increase the air pressure in the laundry treating chamber 111, thereby making the air pressure in the laundry treating chamber 111 consistent with the external air pressure.

[0082] By providing the third channel portion 243 and connecting the second air hole 2251 to the third channel portion 243, the position of the second air hole 2251 can be adjusted by changing the position of the third channel portion 243, so as to reasonably arrange the position of the second air hole 2251, thereby enabling the top-opening type clothing treatment device 100 to have better overall coordination.

[0083] In some embodiments of the present application, such as Figure 5 or Figure 7 shown, the gas channel 24 includes a first channel portion 2261, a second channel portion 242, and a third channel portion 243. The filter member 23 separates the first channel portion 2261 and the second channel portion 242. The second channel portion 242 surrounds the circumferential direction of the top opening of the clothing treatment cavity 111, and the second channel portion 242 is respectively connected to the first channel portion 2261 and the third channel portion 243. The first air hole 221 is connected to the first channel portion 2261, and the second air hole 2251 is connected to the third channel portion 243.

[0084] Specifically, the second channel portion 242 has a U-shaped structure. Among them, the U-shaped structure covers the front side, left side, and right side of the top opening of the clothing treatment cavity 111. The two ends of the U-shaped structure are arranged facing the rear side of the top opening. The third channel portion 243 is arranged at the rear side of the top opening (i.e., the rear side of the top of the top-opening type clothing treatment device 100), so that the second air hole 2251 is arranged away from the front side of the top-opening type clothing treatment device 100, thereby enabling the top-opening type clothing treatment device 100 to have better appearance coordination.

[0085] It should be understood that by setting the extending direction of the second channel portion 242, the second channel portion 242 has a certain length. When the washing water and foam pass through the filter member 23 and enter the second channel portion 242, the structure of the second channel portion 242 can accommodate the washing water and foam, reducing the situation where the washing water and foam reach the third channel portion 243, and further reducing the occurrence of the situation where the washing water and foam overflow.

[0086] It should be noted that along the circumferential direction of the top opening, the length of the second channel portion 242 covers one-fourth, one-third, one-half, or three-fourths, etc. of the circumferential area of the top opening.

[0087] It should be pointed out that in the present application, when the user faces the top-opening clothing processing device 100, the side of the top-opening clothing processing device 100 facing the user is the front side, the side of the top-opening clothing processing device 100 away from the user is the back side, the side of the top-opening clothing processing device 100 located on the left hand side of the user is the left side, the side of the top-opening clothing processing device 100 located on the right hand side of the user is the right side, the side of the top-opening clothing processing device 100 facing the ground is the bottom side, and the side of the top-opening clothing processing device 100 away from the bottom surface is the top side.

[0088] In some embodiments of the present application, Figure 7 As shown, the opening direction of the first air hole 221 of the top cover assembly 20 is set along the first direction a, and the opening direction of the second air hole 2251 is set along the second direction b, wherein the first direction a is a vertical direction, and the first direction a and the second direction b are intersected.

[0089] Specifically, when the top cover assembly 20 is in use, the top cover assembly 20 is installed on the top of the top-opening clothing processing device 100 and is used to open or close the top opening of the clothing processing chamber 111. The first air hole 221 is connected to the clothing processing chamber 111, and the first air hole 221 is arranged to be opened along the first direction a, so that washing water and bubbles are not easy to enter the gas channel 24 from the first air hole 221 under the action of their own gravity, thereby further reducing the overflow of washing water and bubbles.

[0090] In addition, the opening direction of the second air hole 2251 is set along the second direction b, so that the opening direction of the second air hole 2251 is set at an angle to the vertical direction, thereby reducing the situation where foreign matter enters the gas channel 24 from the second air hole 2251, and further reducing the situation where foreign matter blocks the passage of air. At the same time, because the opening directions of the second air hole 2251 and the first air hole 221 intersect, the gas with water vapor and foam needs to change the airflow direction after entering the first air hole 221, thereby further reducing the situation where washing water and bubbles overflow from the second air hole 2251.

[0091] It should be noted that the second direction b is arranged to intersect with the first direction a, and the angle between the second direction b and the first direction a may be 20°, 30°, 60°, 90°, 120° or 150°, etc.

[0092] In some embodiments of the present application, Figure 3 and Figure 4 As shown, there are multiple first channel portions 2261 . Along the extension direction of the second channel portion 242 , the multiple first channel portions 2261 are respectively connected to the second channel portion 242 , and each first channel portion 2261 is correspondingly connected to at least one first air hole 221 .

[0093] Specifically, by providing a plurality of first channel portions 2261, the exhaust area of the top cover assembly 20 can be increased, and when the top cover assembly 20 is used in the laundry treating apparatus 100, the ventilation effect of the laundry treating chamber of the laundry treating apparatus 100 can be improved.

[0094] It should be understood that in the extending direction of the second channel portion 242, the plurality of first channel portions 2261 are arranged at intervals, and the intervals can be equal or unequal.
