DETAILED DESCRIPTION

[0035] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the technical solutions provided by the present application. It will be apparent, however, to one of ordinary skill in the art that the technical solutions provided by the present application can be practiced without one or more of these specific details.

[0036] It should be noted that the terms used herein are only used to describe specific embodiments and are not intended to limit exemplary embodiments according to the present application.

It will be further understood that the terms "comprise" and / or "include" when used herein specify the presence of stated features, integers, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups thereof.

[0037] Exemplary embodiments according to the present application will now be described in detail with reference to the accompanying drawings. The exemplary embodiments may, however, be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It will be understood that the embodiments are set forth herein to convey the substance of the present application and to fully and completely disclose the best mode contemplated by the inventors of carrying out the present application. Accordingly, the exemplary embodiments are set forth so as to describe the principles of the present application in a comprehensive manner.

[0038] The laundry treating apparatus in the related art, such as a drum washing machine, usually sets a door assembly at the front end of the apparatus to close the laundry loading port of the apparatus, wherein the circumferential side of the door glass on the door assembly is usually set as a central symmetric rotation body, and in order to avoid the interference between the door glass and the door seal when the door is opened, the gap between the circumferential side of the door glass and the inner drum is usually large. Thus, during the working process of the laundry treating apparatus, small clothes or the corners of large clothes are easy to fall into or squeeze into the door seal from the gap between the circumferential side of the door glass and the inner drum, or fall into the gap between the inner drum and the outer barrel, which affects the cleaning effect of the clothes and causes wear to the clothes, affecting the user experience. The above content is not an admission of the prior art by the present application.

[0039] The embodiments of the present application provide a door glass, a door assembly and a laundry treating apparatus, which improve the door glass, the door assembly and the laundry treating apparatus.

[0040] As shown in FIGS. 1-8, the embodiments of the present application provide a door glass 100, a door assembly 200 and a laundry treating apparatus 300, wherein the door glass 100 is applied to the door assembly 200, and the door assembly 200 is applied to the laundry treating apparatus 300.

[0041] The laundry treating apparatus 300 is usually a drum washing machine, a dryer, a washing-drying integrated machine, etc. It can be understood that the capacity of the laundry treating apparatus 300 can be small (3-5 kg), medium (6-8 kg), large (9 kg or more), mini (less than 3 kg), etc.

[0042] Further, as shown in FIGS. 3, 4 and 5, the laundry treating apparatus 300 includes an outer barrel 310 and an inner drum 320, the inner drum 320 is rotatably arranged in the outer barrel 310, the outer barrel 310 is provided with a laundry loading port 311, and the inner drum 320 is provided with an open port 321 at a position opposite to the laundry loading port 311, so that the laundry can be placed in or taken out of the inner drum 320 through the laundry loading port 311 and the open port 321. The laundry treating apparatus 300 further includes the door assembly 200, and the door assembly 200 is rotatable relative to the outer barrel 310 to open or close the laundry loading port 311. The laundry treating apparatus 300 further includes a door seal 330, which is mounted at the laundry loading port 311 of the outer barrel 310. The door assembly 200 includes a door body 210 and the door glass 100 mounted on the door body 210. The door body 210 is rotatable relative to the outer barrel 310 to drive the door glass 100 to sealingly connect with the door seal 330, so as to close the laundry loading port 311. The door body 210 is rotatable relative to the outer barrel 310 to drive the door glass 100 to separate from the door seal 330, so as to open the laundry loading port 311.

[0043] The circumferential side of the door glass in the related art is usually configured as a central symmetric rotation body, and in order to avoid interference between the door glass and the door seal when the door is opened, the gap between the circumferential side of the door glass and the inner cylinder is usually large. In this way, during the operation of the clothes processing equipment, small clothes are easily dropped into the door seal from the gap between the circumferential side of the door glass and the inner cylinder, causing the small clothes to be not washed clean; or small clothes are easily dropped into the gap between the inner cylinder and the outer barrel, causing the clothes to be scratched by the inner cylinder; or the corners of large clothes are squeezed to the outside of the inner cylinder and are scratched by the door seal.

[0044] Therefore, as shown in FIGS. 1 and 2, embodiments of the first aspect of the present application provide a door glass 100 for sealing a door seal 330 of a clothes processing equipment 300, the door glass 100 is formed with a water sealing ring 110 configured to be sealingly connected with the door seal 330, the door glass 100 includes a top end 120 arranged towards an inner cylinder 320 of the clothes processing equipment 300, and a side wall 130 connecting the water sealing ring 110 and the top end 120; wherein the end of the inner cylinder 320 close to the door seal 330 is provided with an open mouth 321, the gap distance between the inner wall of the open mouth 321 and the side wall 130 at the corresponding position is D, the minimum safety gap value between the inner wall of the open mouth 321 and the side wall 130 at the corresponding position is d, and the difference between D and d is in the range of 0 mm to 20 mm.

[0045] The door glass 100 provided by the embodiments of the present application includes the water sealing ring 110, the top end 120 and the side wall 130, and is sealingly connected with the door seal 330 through the water sealing ring 110, so as to realize the sealing connection between the door glass 100 and the door seal 330, and further seal and close the clothes feeding opening 311 of the clothes processing equipment 300, so as to ensure the reliability of the related operation of the clothes processing equipment 300. The related operation of the clothes processing equipment 300 can include washing operation, drying operation, barrel cleaning operation, etc.

[0046] When the door glass 100 is separated from the door seal 330, the side wall 130 of the door glass 100 can interfere with the open mouth 321 of the inner barrel 320, causing the side wall 130 to be stuck or to scratch the inner wall of the open mouth 321. Therefore, in the design process, when the water sealing ring 110 is sealingly connected with the door seal 330, by reasonably designing the safety gap between the inner wall of the open mouth 321 and the side wall 130 of the door glass 100, that is, the safety distance of the gap between the two, it can be ensured that the door glass 100 will not interfere with the door seal 330 during the separation process. In the actual design process, the safety gap can be a size range, that is, when the gap distance between the inner wall of the open mouth 321 and the side wall 130 of the door glass 100 is designed to be any size value within the range of the safety gap, it can be ensured that the door glass 100 will not interfere with the door seal 330 during the separation process. Wherein the minimum safety value in the size range corresponding to the safety gap is defined as the second size, that is, the minimum safety gap value between the inner wall of the open mouth 321 and the side wall 130 when the water sealing ring 110 is sealingly connected with the door seal 330, that is, in this case, during the separation process of the door glass 100 and the door seal 330, the side wall 130 of the door glass 100 can just smoothly pass through the open mouth 321. If the value of the second size is reduced on the basis of the minimum safety value, the value of the second size exceeds the range corresponding to the safety gap, then the side wall 130 of the door glass 100 will interfere with the open mouth 321 during the separation process of the door glass 100 and the door seal 330. If the value of the second size is increased on the basis of the minimum safety value, the value of the second size still belongs to the range corresponding to the safety gap, then the side wall 130 of the door glass 100 will not interfere with the open mouth 321 during the separation process of the door glass 100 and the door seal 330. However, this will increase the gap width between the inner wall of the open mouth 321 and the side wall 130 of the door glass 100.

[0047] In the embodiment, when the water sealing ring 110 is sealingly connected with the door seal 330, the gap distance between the inner wall of the opening 321 and the side wall 130 is defined as the first size, and the minimum safety gap value between the inner wall of the opening 321 and the side wall 130 is defined as the second size. By limiting the difference between the first size and the second size at the same position to be 0mm to 20mm, it can be ensured that, during the separation of the door glass 100 and the door seal 330 in actual use, the side wall 130 of the door glass 100 can smoothly pass through the opening 321 without interference, and when the door glass 100 is sealingly connected with the door body 210, the gap distance between the side wall 130 of the door glass 100 and the inner wall of the opening 321 of the inner cylinder 320 is as small as possible. Therefore, the possibility of the corners of small or large clothes falling into or being squeezed into the door seal 330 from the gap between the circumferential side of the door glass 100 and the inner cylinder 320, or falling into the gap between the inner cylinder 320 and the outer barrel 310 can be reduced, the cleaning effect of the clothes can be improved, the wear of the clothes can be reduced, the satisfaction of the user can be improved, and the user experience can be improved.

[0048] Further, by limiting the difference between the first size and the second size at the same position to be 0mm to 20mm, the gap distance (i.e. the first size) between the side wall 130 at different positions and opposite positions on the inner wall of the opening 321 along the circumferential direction of the opening 321 can be different, i.e. the side wall 130 of the door glass 100 is not a symmetrical rotating body. Therefore, during the separation of the door glass 100 and the door seal 330 in actual use, the side wall 130 of the door glass 100 can smoothly pass through the opening 321 without interference, and when the door glass 100 is sealingly connected with the door body 210, the gap distance at each position between the side wall 130 of the door glass 100 and the inner wall of the opening 321 of the inner cylinder 320 is as small as possible. In order to further reduce the possibility of the clothes contacting the door seal 330, the gap between the inner cylinder 320 and the outer barrel 310, improve the cleaning effect of the clothes, and reduce the wear of the clothes.

[0049] Specifically, the difference between the first size and the second size at the same position can be 0mm, 1mm, 3mm, 5mm, 10mm, 15mm, 20mm, or other size values. It can be understood that the difference between the first size and the second size at the same position can be reasonably designed according to the machining error of the door glass 100, the machining error of the inner cylinder 320, the assembly error of the door glass 100 and the inner cylinder 320, etc.

[0050] Further, when the second size is the minimum safety gap value between the inner wall of the open hole 321 and the side wall 130 when the water sealing ring 110 is sealingly connected with the door seal 330, in theory, the side wall 130 of the door glass 100 can just smoothly pass through the open hole 321 during the separation of the door glass 100 and the door seal 330, but in the actual scene, due to factors such as machining error, assembly error, and use wear, there is a risk of interference between the side wall 130 of the door glass 100 and the open hole 321. Therefore, the minimum value of the difference range of the first size and the second size at the same position can be greater than 0 mm, such as the minimum value of the difference range of the first size and the second size at the same position can be 0.2 mm, 0.5 mm, 0.8 mm, 1 mm, 1.5 mm, or other size values, and correspondingly, the difference range of the first size and the second size at the same position can be 0.2 mm to 20 mm, 0.5 mm to 20 mm, 0.8 mm to 20 mm, 1 mm to 20 mm, 1.5 mm to 20 mm, or other size ranges, which can ensure that the side wall 130 of the door glass 100 smoothly passes through the open hole 321 without interference during the separation of the door glass 100 and the door seal 330, and ensure that the gap distance between the side wall 130 of the door glass 100 and the inner wall of the open hole 321 of the inner barrel 320 at each position is as small as possible when the door glass 100 is sealingly connected with the door body 210.

[0051] Further, as shown in FIGS. 1 and 2, the water sealing ring 110 of the door glass 100 is provided with a connecting ring 140 away from the side of the top end 120, and the door glass 100 can be installed on the door body 210 through the connecting ring 140.

[0052] As shown in FIGS. 1, 2, 6 and 7, in some possible implemented embodiments provided by the present application, the side wall 130 includes a first section 131 along the circumference of the water sealing ring 110, and the first section 131 is arranged close to the door body pivot of the laundry treating apparatus 300. When the water sealing ring 110 is sealingly connected with the door seal 330, the minimum value of the gap distance between the first section 131 and the inner wall of the open hole 321 is 10 mm to 30 mm.

[0053] As shown in FIG. 3, the laundry treating apparatus 300 further includes a cabinet 350, and the outer barrel 310 is arranged in the cabinet 350. The cabinet 350 is provided with a avoiding hole at a position opposite to the laundry dropping opening, and the door body 210 of the laundry treating apparatus 300 is rotationally connected with the cabinet 350 outside the outer barrel 310 through the door body pivot, so that the door glass 100 can be sealingly connected or separated with the door seal 330 close to or away from the laundry dropping opening 311 with the door body pivot as the axis.

[0054] In this embodiment, since the first section 131 is distributed along the circumference of the water sealing ring 110, the first section 131 can be approximately in the shape of an arc, and when the water sealing ring 110 is sealingly connected with the door seal 330, the gap between the first section 131 and the inner wall of the open hole 321 can be approximately in the shape of a partial ring. By reasonably designing the minimum value of the gap distance between the first section 131 and the inner wall of the open hole 321, it can be ensured that, when the water sealing ring 110 is sealingly connected with the door seal 330, the gap distance between the first section 131 and the inner wall of the open hole 321 is small, and the possibility that the corners of small or large clothes fall into or are squeezed into the door seal 330 or fall into the gap between the inner drum 320 and the outer tub 310 is reduced, the processing effect of the clothes is improved, such as the cleaning effect of the clothes, the wear of the clothes is reduced, the service life of the clothes is prolonged, and the user's satisfaction is improved.

[0055] Further, as shown in FIG. 3, the clothes processing apparatus 300 further includes door locks 340, and the door locks 340 and the shafts are distributed on opposite sides of the clothes feeding opening 311. Thus, when the water sealing ring 110 of the door glass 100 is sealingly connected with the door seal 330, the gap distance between the door glass 100 and the inner wall of the open hole 321 of the inner drum 320 gradually increases from the shaft to the door lock 340, that is, the closer the gap between the door glass 100 and the inner wall of the open hole 321 of the inner drum 320 is to the shaft, the smaller the gap distance is, and the closer the gap is to the door lock 340, the larger the gap distance is. Therefore, the minimum value of the gap distance between the first section 131 of the side wall 130 of the door glass 100 and the inner wall of the open hole 321 can be understood as the gap distance between the first section 131 and the inner wall of the open hole 321 at the position opposite to the shaft of the door body, as shown by M in FIG. 7.

[0056] Specifically, the minimum value M of the gap distance between the first section 131 and the inner wall of the open hole 321 when the water sealing ring 110 is sealingly connected with the door seal 330 can be 10 mm, 15 mm, 20 mm, 25 mm, 30 mm, or other size values. It can be understood that the gap distance between the first section 131 and the inner wall of the open hole 321 when the water sealing ring 110 is sealingly connected with the door seal 330 can be reasonably designed according to the machining and assembly errors of the door glass 100, the door body 210, and the shaft, and the machining and assembly errors of the outer tub 310, the inner drum 320, the door seal 330, and other components.

[0057] In the above embodiment, when the water sealing ring 110 is sealingly connected with the door seal 330, the minimum value M of the gap distance between the first section 131 and the inner wall of the open hole 321 is 15mm to 20mm, that is, the size value M of the gap distance between the first section 131 and the inner wall of the open hole 321 at the position opposite to the rotation shaft is 15mm to 20mm, and specifically, when the water sealing ring 110 is sealingly connected with the door seal 330, the gap distance M between the first section 131 and the inner wall of the open hole 321 at the position opposite to the rotation shaft can be 15mm, 17mm, 19mm, 20mm, or other size values.

[0058] Specifically, when the water sealing ring 110 is sealingly connected with the door seal 330, the minimum value M of the gap distance between the first section 131 and the inner wall of the open hole 321 can be greater than 15mm, and further, the minimum value M of the gap distance between the first section 131 and the inner wall of the open hole 321 can be 19mm, 19.3mm, 19.8mm, etc.

[0059] As shown in FIG. 1, FIG. 2 and FIG. 7, in some possible implemented embodiments provided by the present application, the side wall 130 includes a second section 132 along the circumference of the water sealing ring 110, the second section 132 is arranged close to the door lock 340 of the laundry treating apparatus 300, and the second section 132 is provided with a first cutaway surface 133.

[0060] Since the second section 132 is distributed along the circumference of the water sealing ring 110, the second section 132 can be substantially in the shape of a circular arc, by arranging the first cutaway surface 133 on the second section 132 of the side wall 130 close to the door lock 340, when the water sealing ring 110 is sealingly connected with the door seal 330, the size value of the gap distance between the side wall 130 and the inner wall of the open hole 321 can be as small as possible, and the first cutaway surface 133 can reduce the possibility of interference between the door glass 100 and the open hole 321 of the inner drum 320 or the door seal 330 during the separation of the door glass 100 and the door seal 330, thereby ensuring that the door glass 100 can be smoothly separated from the door seal 330, and making the gap distance between the second section 132 and the inner wall of the open hole 321 of the inner drum 320 smaller, that is, the cutaway surface is processed as little as possible, thereby reducing the possibility that the corners of small or large laundry fall into or squeeze into the door seal 330 or the gap between the inner drum 320 and the outer drum 310 from the gap between the second section 132 and the inner wall of the open hole 321, improving the treating effect of the laundry, such as improving the cleaning effect of the laundry, reducing the wear of the laundry, prolonging the service life of the laundry, and improving the satisfaction of the user.

[0061] That is, as shown in FIGS. 6 and 7, the side wall of the door glass 100 is not a central symmetric rotation body, and when the door glass 100 is sealingly connected with the door seal 330, the gap between the side wall 130 close to the door body rotation shaft side and the inner wall of the open hole 321 of the inner cylinder 320 is smaller than the gap between the side wall 130 close to the door lock 340 side and the inner wall of the open hole 321 of the inner cylinder 320, so as to ensure that the door glass 100 does not interfere with the inner cylinder 320 and the door seal 330 during the separation of the door glass 100 and the door seal 330, and the gap distance between the door glass 100 and the inner wall of the open hole 321 of the inner cylinder 320 is small, reducing the possibility of the clothes contacting the gap between the door seal 330, the inner cylinder 320 and the outer barrel 310, improving the cleaning effect of the clothes, and reducing the wear of the clothes.

[0062] In some possible implementation embodiments provided by the present application, the gap distance between the door seal 330 and the first cutaway surface 133 at the corresponding position during the separation of the door glass 100 and the door seal 330 is 1 mm to 2 mm.

[0063] That is, during the separation of the door glass 100 and the door seal 330, the gap distance between the lip of the door seal 330 and the first cutaway surface 133 is small, so that the cutaway amount of the first cutaway surface 133 during processing is as small as possible, and thus the gap distance between the second section 132 and the inner wall of the open hole 321 of the inner cylinder 320 during the sealing connection of the door glass 100 and the door seal 330 is small, reducing the possibility that small clothes fall into the door seal 330 from the gap between the circumferential side of the door glass 100 and the inner cylinder 320, causing the small clothes to be not washed clean; or reducing the possibility that small clothes fall into the gap between the inner cylinder 320 and the outer barrel 310, causing the clothes to be scratched by the inner cylinder 320; or reducing the possibility that the corners of large clothes are squeezed to the outside of the inner cylinder 320 and scratched by the door seal 330, improving the processing effect of the clothes and prolonging the service life of the clothes, and improving the satisfaction of the user.

[0064] Specifically, during the separation of the door glass 100 and the door seal 330, the gap distance between the door seal 330 and the first cutaway surface 133 at the corresponding position can be 1 mm, 1.3 mm, 1.5 mm, 1.8 mm, 2 mm, or other sizes.

[0065] In some examples of the above embodiments, the first cutaway surface 133 is a planar structure, which is convenient to process, easy to implement, and has low processing cost.

[0066] As shown in FIG. 2 and FIG. 3, in some examples of the above embodiments, the first cutaway surface 133 is in an arc structure. Since the laundry loading port 311 is circular, the door seal 330 is in a ring shape, the door glass 100 is substantially cylindrical, the first section 131 of the door glass 100 is close to the door body pivot, the second section 132 of the door glass 100 is close to the door lock 340, and the door lock 340 is distributed on the two sides of the laundry loading port 311 opposite to the pivot. During the rotation of the door body 210 with the door body pivot as the axis, the second section 132 of the door glass 100 needs to pass through the circular door seal 330 with the door body pivot as the axis. Therefore, the first cutaway surface 133 is arranged in an arc structure, which can reduce the distance difference between the door seal 330 and the first cutaway surface 133 at the corresponding position during the separation of the door glass 100 and the door seal 330. Thus, the size difference of the gap distance between the first cutaway surface 133 of the second section 132 and the inner wall of the inner drum 320 can be reduced when the door glass 100 and the door seal 330 are in sealing connection, so that the gap distance between the first cutaway surface 133 and the inner wall of the inner drum 320 is relatively uniform, avoiding the possibility that the laundry falls into or is squeezed into the door seal 330 or the gap between the inner drum 320 and the outer tub 310 from the larger gap between the first cutaway surface 133 and the inner wall of the inner drum 320.

[0067] Further, the arc structure has the door body pivot of the laundry treating apparatus 300 as the processing axis, and the door body 210 rotates relative to the outer tub 310 through the door body pivot. The door body pivot is taken as the processing axis of the arc structure, and the arc structure is processed with the arc as the cutting line. During the separation of the door glass 100 and the door seal 330, the uniformity of the gap distance between the door seal 330 and the first cutaway surface 133 at the corresponding position can be improved, so that the first cutaway surface 133 can pass through the door seal 330 with a relatively constant gap distance, improving the reliability and smoothness of the separation of the door glass 100 and the door seal 330. Meanwhile, when the door glass 100 and the door seal 330 are in sealing connection, the uniformity of the gap distance between the second section 132 and the inner wall of the open port 321 of the inner drum 320 can be improved, so that the gap distance between the first cutaway surface 133 of the second section 132 and the inner wall of the inner drum 320 is relatively uniform, reducing the possibility that the laundry falls into or is squeezed into the door seal 330 or the gap between the inner drum 320 and the outer tub 310 from the gap between the first cutaway surface 133 and the inner wall of the inner drum 320.

[0068] In some possible implementation examples provided in the present application, the top end 120 of the door glass 100 is configured to be extendable to the inside of the inner drum 320.

[0069] In the embodiment, when the door glass 100 is sealingly connected with the door seal 330, the top end 120 extends to the inside of the inner drum 320, so that the top end 120 can hinder the laundry in the inner drum 320 from moving towards the door seal 330, so that the laundry is located in the inner drum 320 as much as possible. Since the inner drum 320 rotates relative to the outer drum 310 during the operation of the laundry treatment apparatus 300 to ensure the treatment effect on the laundry, the door seal 330 is fixed relative to the inner drum 320, and if the laundry falls into the door seal 330, the cleaning or drying effect on the laundry will be affected. Therefore, the extension of the top end 120 to the inside of the inner drum 320 can improve the cleaning or drying effect on the laundry.

[0070] In the above embodiment, when the door glass 100 is sealingly connected with the door seal 330, the length of the door glass 100 extending to the inside of the inner drum 320 is 22mm to 28mm. The length of the door glass 100 extending to the inside of the inner drum 320 is shown as H in FIG. 7, and the length H of the door glass 100 extending to the inside of the inner drum 320 can be understood as the distance between the top end 120 of the door glass 100 and the outer edge of the open port 321 of the inner drum 320. The outer edge of the open port 321 can be understood as the edge of the open port 321 away from the inside of the inner drum 320.

[0071] When the door glass 100 is sealingly connected with the door seal 330, the length H of the door glass 100 extending to the inside of the inner drum 320 is set reasonably, so that the top end 120 of the door glass 100 can effectively prevent the laundry in the inner drum 320 from moving towards the door seal 330, so that the laundry is located in the inner drum 320 as much as possible, reducing the possibility of the laundry contacting the gap between the door seal 330, the inner drum 320 and the outer drum 310, ensuring good cleaning effect, and reducing the wear of the laundry. At the same time, this setting can reduce the space occupied by the door glass 100 in the inner drum 320, so that the inner drum 320 has enough space to accommodate the laundry or treat the laundry, improving the capacity of the laundry treatment apparatus 300, thereby improving the cost performance of the laundry treatment apparatus 300 and improving the user's satisfaction.

[0072] Specifically, when the door glass 100 is sealingly connected with the door seal 330, the length H of the door glass 100 extending to the inside of the inner drum 320 can be 22mm, 24mm, 26mm, 28mm or other sizes. The length H of the door glass 100 extending to the inside of the inner drum 320 can be reasonably designed according to the volume requirement of the inner drum 320, the gap distance size value between the side wall 130 and the inner wall of the open port 321 of the inner drum 320, etc.

[0073] As shown in FIG. 1, FIG. 2, FIG. 4, FIG. 5, FIG. 7 and FIG. 8, in some possible implementation embodiments provided in the present application, the door seal 330 is provided with an air inlet 331, and the side wall 130 is provided with a second cutaway surface 134 on the side close to the air inlet 331, and the second cutaway surface 134 is inclined to the axis close to the water sealing ring 110 in the direction from the water sealing ring 110 to the top end 120.

[0074] In the present application, the laundry treating apparatus 300 can include a drying air duct, such as a dryer, a washer-dryer, etc., and specifically, the air inlet 331 is in communication with the drying air duct, and the airflow in the drying air duct flows into the inner drum 320 through the air inlet 331 to act on the laundry in the inner drum 320 to achieve the drying effect.

[0075] In the present embodiment, the side wall 130 is provided with the second cutaway surface 134 on the side close to the air inlet 331, and the second cutaway surface 134 has a good guiding effect, so that the airflow discharged through the air inlet 331 can flow smoothly and fully into the inner drum 320 under the guiding effect of the second cutaway surface 134.

[0076] In the present application, since the second cutaway surface 134 is located at the top of the laundry treating apparatus 300, by inclining the second cutaway surface 134 to the axis close to the water sealing ring 110 in the direction from the water sealing ring 110 to the top end 120, the airflow discharged through the air inlet 331 can flow smoothly and fully into the middle and bottom of the inner drum 320 through the second cutaway surface 134, and then can more fully contact the laundry in the inner drum 320, to provide the drying efficiency and ensure the good drying effect.

[0077] In some examples of the above embodiments, the air inlet 331 is arranged opposite to at least part of the second cutaway surface 134, i.e., the entire air inlet 331 can be opposite to the second cutaway surface 134, and this arrangement can make the airflow of the air inlet 331 flow fully and quickly into the inner drum 320, to improve the drying efficiency.

[0078] In some examples of the above embodiments, part of the air inlet 331 is opposite to the second cutaway surface 134, and part of the air inlet 331 is not opposite to the second cutaway surface 134, i.e., part of the airflow discharged through the air inlet 331 directly flows into the inner drum 320 under the guiding effect of the second cutaway surface 134, and the other part flows into the inner drum 320 along the circumference of the door glass 100 under the guiding effect of the side wall 130, thereby increasing the area of the airflow discharged through the air inlet 331 flowing through the inner drum 320, improving the comprehensiveness and uniformity of the airflow discharged through the air inlet 331 flowing through the inner drum 320, and improving the comprehensiveness and uniformity of the drying effect and the user's satisfaction.

[0079] In the above embodiments, the second cutaway surface 134 is a planar structure and / or an arc-shaped structure, that is, the second cutaway surface 134 can be a planar structure, an arc-shaped structure, or a combination of a planar structure and an arc-shaped structure. Among them, the planar structure is convenient to process and has a lower cost. The edge of the arc-shaped structure is relatively smooth, which can smoothly transition with the side wall 130 of the door glass 100, play a good guiding role, improve the smoothness of the air flow discharged by the air inlet 331 flowing along the circumference of the door glass 100, and then increase the area of the air flow discharged by the air inlet 331 flowing through the inner cylinder 320, which is beneficial to improve the comprehensiveness and uniformity of the drying effect.

[0080] In the above embodiments, as shown in FIGS. 1 and 5, the second cutaway surface 134 is connected with the top end 120, that is, the second cutaway surface 134 penetrates the top end 120, so that the air flow discharged by the air inlet 331 can smoothly and sufficiently flow into the middle part of the inner cylinder 320 through the second cutaway surface 134, to achieve a good drying effect.

[0081] As shown in FIGS. 3 and 6, in some possible implemented embodiments provided by the present application, during the rotation of the inner cylinder 320 relative to the outer barrel 310, the drum laundry treatment equipment 300 drives the laundry in the inner cylinder 320 to rotate, and the laundry falls and drops under the action of gravity after reaching a suitable height, to achieve cleaning of the laundry. By arranging the second cutaway surface 134 at the top of the laundry treatment equipment 300, the opportunity of the laundry contacting the second cutaway surface 134 can be minimized, and the possibility of the laundry contacting the gap between the second cutaway surface 134 and the door seal 330, or the gap between the inner cylinder 320 and the outer barrel 310 can be reduced, or even if the laundry contacts the second cutaway surface 134, since the second cutaway surface 134 is located at a higher position, the force of the laundry at this position is smaller, and the possibility of the laundry contacting the gap between the second cutaway surface and the inner cylinder 320 and the gap between the door seal 330 or the inner cylinder 320 and the outer barrel 310 is also smaller, thereby improving the cleaning effect and reducing the wear of the laundry.

[0082] As shown in FIG. 2, the second cutaway surface 134 is located between the first section 131 of the door glass 100 and the second section 132 of the door glass 100, the first section 131 is close to the door body rotating shaft, and the second section 132 is close to the door lock 340, so that the first section 131 and the second section 132 can be distributed on opposite sides of the laundry treatment equipment 300, thereby the door glass 100 and the door seal 330 can be sealingly connected or separated by rotating the door body 210 from one side relative to the other side at the front side of the laundry treatment equipment 300, which is simple to operate and conforms to the ergonomic design.

[0083] Further, the two ends of the second cutaway surface 134 are arc-shaped structures along the circumference of the water sealing ring 110, and the middle part of the second cutaway surface 134 is a planar structure, which is smoothly connected with the first section 131 and the second section 132 through the arc-shaped structures at the two ends, so that part of the airflow discharged through the air inlet 331 can flow along the circumferential side of the open port 321 of the inner cylinder 320 through the arc-shaped structures, and part of the airflow flows to the middle part of the inner cylinder 320 through the planar structure, thereby increasing the area of the airflow discharged through the air inlet 331 flowing through the inner cylinder 320, which is conducive to improving the comprehensiveness and uniformity of the drying effect.

[0084] As shown in FIG. 1, in some possible implemented embodiments provided by the present application, a guide surface 111 is arranged on the water sealing ring 110, and the guide surface 111 is arranged to be inclined towards the axis close to the water sealing ring 110 along the direction from the side wall 130 to the top end 120. The arrangement of the guide surface 111 can improve the sealing performance of the connection between the water sealing ring 110 and the door seal 330.

[0085] The door seal 330 includes a lip, and the water sealing ring 110 is connected with the lip of the door seal 330, so that the sealing connection between the door glass 100 and the door seal 330 can be achieved.

[0086] Further, the second cutaway surface 134 is connected with the guide surface 111, that is, the second cutaway surface 134 connects the guide surface 111 and the top end 120, so that the area of the second cutaway surface 134 can be increased, the flow guiding effect of the second cutaway surface 134 can be improved, the drying effect can be ensured to be good, and the drying efficiency can be improved.

[0087] It can be understood that, in order to reduce the possibility that the clothes contact the gap between the second cutaway surface 134 and the inner wall of the open port 321 and the gap between the door seal 330 and the inner cylinder 320 and the outer drum 310, the cutaway amount of the second cutaway surface 134 should be as small as possible.
