DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of this application.

[0029] See also Figure 1 , Figure 2 and Figure 3 The embodiment of the present application provides a door assembly 110, including a door body 30, wherein the door body 30 includes a bottom plate 31 and a side plate 32, wherein the side plate 32 is arranged around the bottom plate 31 and connected to the bottom plate 31, and a protrusion 10 is provided on the side of the bottom plate 31 away from the side plate 32.

[0030] The door assembly 110 provided in the embodiment of the present application includes a door body 30, and a protrusion 10 is provided on the side of the bottom plate 31 of the door body 30 facing away from the side plate 32. When the door assembly 110 is installed on the washing machine, the bottom plate 31 of the door body 30 is set toward the inner drum 130 of the washing machine. When the washing machine is working, the clothes in the inner drum 130 of the washing machine can rub against the protrusion 10 on the surface of the bottom plate 31 of the door body 30 when the inner drum 130 rotates, thereby promoting the separation of dirt and clothes, and then the cleaning effect of the clothes can be improved, thereby improving the washing ratio of the washing machine.

[0031] See also Figure 3 A plurality of protrusions 10 are provided on the side of the bottom plate 31 away from the side plate 32. The plurality of protrusions 10 are arranged in sequence and spaced apart in a first direction X. The plurality of protrusions 10 extend in a second direction Y. The first direction X and the second direction Y are perpendicular to each other.

[0032] See also Figure 3The raised portion 10 may be in a strip shape, that is, the length of the raised portion 10 in the second direction Y is greater than the width of the raised portion 10 in the first direction X. At this time, the raised portion 10 may act as a clothes rubbing rod. Compared with the point-shaped or block-shaped raised portions 10, the strip-shaped raised portions 10 have a stronger pulling and friction effect on the clothes, thereby achieving a stronger cleaning effect.

[0033] See also Figure 3 The raised portion 10 may be straight in its extension direction (second direction Y), or the raised portion 10 may be wavy in its extension direction (second direction Y), so as to increase the friction area between the raised portion 10 and the clothes, thereby improving the cleaning effect of the clothes.

[0034] See also Figure 1 and Figure 3 , the protrusion 10 may be in the shape of a pyramid. It is understandable that when the protrusion 10 is in the shape of a pyramid, the interface between the protrusion 10 and the bottom plate 31 is a side surface of the pyramid.

[0035] It can be understood that when the protrusion 10 is in a pyramid shape, the cross section of the protrusion 10 is a polygon, such as a triangle, a rectangle (square or rectangle), a pentagon or a hexagon.

[0036] Exemplarily, the outer surface of the raised portion 10 includes a first inclined surface S11 and a second inclined surface S12, wherein the angle between the first inclined surface S11 and the bottom plate 31 is greater than 0 and less than 90° (for example, 10°, 20°, 30°, 45°, 60°, 70°, 80°, etc.), and the angle between the second inclined surface S12 and the bottom plate 31 is greater than 0 and less than 90° (for example, 10°, 20°, 30°, 45°, 60°, 70°, 80°, etc.).

[0037] Exemplarily, the angle between the first inclined surface S11 and the second inclined surface S12 is greater than 0 and less than 180° (for example, 10°, 30°, 45°, 60°, 90°, 120°, 135°, 150°, 160°, 170°, etc.).

[0038] In some embodiments, the included angle between the first inclined surface S11 and the bottom plate 31 is 45°, and the included angle between the second inclined surface S12 and the bottom plate 31 is 45°.

[0039] In some other embodiments, the plurality of protrusions 10 disposed on the side of the bottom plate 31 away from the side plate 32 may also be arranged in an array.

[0040] In some embodiments, the outer surface of the protrusion 10 may also be arc-shaped.

[0041] In some embodiments, the outer surface of the side panel 32 of the door body 30 may also be provided with a first raised structure. When the washing machine is working, the first raised structure on the outer surface of the side panel 32 may also rub against the clothes, thereby promoting the separation of dirt and clothes, thereby improving the cleaning effect of the clothes and improving the washing ratio of the washing machine.

[0042] Illustratively, the outer surface of the first protruding structure may be arc-shaped, or include a plurality of inclined surfaces connected in sequence.

[0043] Exemplarily, the first protrusion structure may be straight in its extension direction, or the first protrusion structure may be wavy in its extension direction, so as to increase the friction area between the first protrusion structure and the clothes, thereby improving the cleaning effect of the clothes.

[0044] See also Figure 1 and Figure 2 The door assembly 110 further includes a door outer ring 21 and a door inner ring 22 which are arranged opposite to each other and fixedly connected. Exemplarily, the door outer ring 21 and the door inner ring 22 can both be made of plastic.

[0045] Exemplarily, the door outer ring 21 and the door inner ring 22 may be connected by means of screws or by means of snap-on connections.

[0046] See also Figure 1 and Figure 3 One end of the side plate 32 of the door body 30 that is away from the bottom plate 31 extends outward to form a flange 33 , and the flange 33 is clamped between the door outer ring 21 and the door inner ring 22 .

[0047] See also Figure 1 and Figure 2 The door assembly 110 also includes an anti-scalding cover 60 , which is connected to the door outer ring 21 , and is arranged opposite to the door body 30 , and is located on the side of the side plate 32 away from the bottom plate 31 .

[0048] It is understandable that when the washing machine is used in cold seasons or when the dirt on the clothes is difficult to remove, higher temperature water can be used to wash the clothes. Since the door body 30 in the door assembly 110 is in direct contact with the clothes during washing, the temperature of the door body 30 is close to the washing water temperature, and the temperature of the door body 30 can easily hurt the user. Since there is air isolation between the anti-scalding cover 60 and the door body 30, the heat transfer is reduced, so that the anti-scalding cover 60 can maintain a lower temperature, thereby achieving the purpose of anti-scalding.

[0049] Exemplarily, the anti-scalding cover 60 and the door outer ring 21 may be connected by adhesive (such as 3M adhesive) or by a snap-on connection.

[0050] See also Figure 1 The side surface of the anti-scald cover 60 facing the bottom plate 31 of the door body 30 is connected to the light source 40 by an adhesive 50. For example, the adhesive 50 can be 3M adhesive.

[0051] Exemplarily, the door body 30 is made of glass or a light-transmitting resin material. Exemplarily, the light-transmitting resin material may be polycarbonate (PC) or polymethyl methacrylate (PMMA).

[0052] Exemplarily, the material of the anti-scalding cover 60 is glass or a light-transmitting resin material. Exemplarily, the light-transmitting resin material may be polycarbonate (PC) or polymethyl methacrylate (PMMA).

[0053] See also Figure 1 and Figure 2 The door assembly 110 further includes a light source 40. The anti-scalding cover 60 and the door body 30 enclose an accommodating space, and the light source 40 is located in the accommodating space.

[0054] It is understandable that the main function of the light source 40 is to facilitate the user to use the washing machine at night. The washing machine tub light can illuminate the inside of the washing machine, allowing the user to clearly see the inside of the washing machine. When using the washing machine at night, turning on the light source 40 can make it easier for the user to operate the washing machine and avoid improper operation in the dark;

[0055] In addition, since a raised portion 10 is provided on the bottom plate 31 of the door body 30 of the door assembly 110 of the embodiment of the present application, when the outer surface of the raised portion 10 includes an inclined surface (for example, when the raised portion 10 is in the shape of a pyramid), the light (white light) emitted by the light source 40 will be refracted and scattered when passing through the raised portion 10, thereby forming a rainbow on the rear cover 132 of the inner drum 130 of the washing machine, thereby improving the user experience.

[0056] See also Figure 1 , the light source 40 is connected to the anti-scalding cover 60.

[0057] Exemplarily, the light source 40 may be a fluorescent lamp (fluorescent lamp) or an LED lamp.

[0058] In some embodiments, the light source 40 may be a color-changing light. When the washing machine is in different states, the color of the light emitted by the light source 40 is different to indicate the working state of the washing machine. For example, when the temperature of the washing water in the washing machine is low, the light emitted by the light source 40 may be cold light (such as blue); when the temperature of the washing water in the washing machine is high, the light emitted by the light source 40 may be warm light (such as red) to indicate to the user that the temperature in the washing machine is high, and to remind the user to reduce touching the door assembly 110 of the washing machine to reduce or avoid burns.

[0059] See also Figure 4 and Figure 5 The embodiment of the present application further provides a washing machine 100, comprising the door assembly 110 in any of the above embodiments.

[0060] See also Figure 4 and Figure 5 The washing machine 100 includes a housing 120 , and the door assembly 110 is mounted on the housing 120 , and the door assembly 110 is rotatably connected to the housing 120 .

[0061] Exemplarily, the door assembly 110 and the housing 120 are rotatably connected via a hinge.

[0062] Exemplarily, the washing machine 100 is a drum-type washing machine 100 .

[0063] See also Figure 4 The washing machine 100 further includes an inner drum 130 , and the inner drum 130 includes a drum body 131 and a rear cover 132 , and the rear cover 132 is disposed corresponding to the door assembly 110 .

[0064] In some embodiments, a second protrusion structure may also be provided on the inner surface of the rear cover 132. When the washing machine 100 is working, the second protrusion structure on the inner surface of the rear cover 132 may also rub against the clothes, thereby promoting the separation of dirt and clothes, thereby improving the cleaning effect of the clothes and improving the washing ratio of the washing machine 100.

[0065] Illustratively, the outer surface of the second protruding structure may be arc-shaped, or include a plurality of inclined surfaces connected in sequence.

[0066] Exemplarily, the second protrusion structure may be straight in its extension direction, or the second protrusion structure may be wavy in its extension direction, so as to increase the friction area between the second protrusion structure and the clothes, thereby improving the cleaning effect of the clothes.

[0067] For example, the washing machine 100 may further include an outer drum, which is sleeved on the outer side of the inner drum 130. For example, an elastic member (such as a spring) may be provided between the inner drum 130 and the outer drum, and when the inner drum 130 shakes during rotation, the elastic member may buffer a part of the pressure, thereby reducing the shaking of the outer drum, and further reducing the vibration and noise of the washing machine 100.
