[0059] The type of the OLED component 15 is not limited, and may be, for example, an OLED (Organic Light-Emitting Diode) component.

[0060] For example, see Fig.12 The knob assembly 1 further includes an LED assembly 16 having an LED display area 16a, and the LED assembly 16 is disposed in the accommodating space 11a.

[0061] The type of LED component 16 is not limited. For example, the LED component may have a graphic area and at least one light source 162. The part of the pattern area corresponding to the light source 162 may be preset with text or patterns. When the light source 162 is turned on, the corresponding text area or pattern area on the graphic area may be highlighted.

[0062] The window cover 14 is used to see through the information displayed by the OLED assembly 15, and when the light source 162 of the LED assembly 16 is turned on, the corresponding text area or pattern area on the graphic area is highlighted.

[0063] Exemplarily, the ratio of the projection area of ​​the first display area and the second display area on the window cover 14 to the total area of ​​the window cover 14 is not less than 40%. The ratio is, for example, 40%, 43%, 45%, 47%, 50%, 52%, 54%, 56%, 59%, 60%, 63%, 67%, 68%, 70%, 71%, 75%, 79%, 80%, 81%, 86%, 90%, 95%, 99%, etc. This ratio range is conducive to displaying more information, thereby improving the convenience of use.

[0064] The knob assembly of the embodiment of the present application is provided with an electric control assembly 13, a knob ring 11 and a display device, and the display device is provided to include a first display area and a second display area. The first display area is an OLED display area 15a or a TFT display area for displaying information, and the second display area is an LED display area 16a. The knob ring 11 is driven to rotate to trigger the electric control assembly 13 to generate an electric signal. The first display area can display corresponding information according to different electric signals, and the second display area can also light up the corresponding light source 162 according to different electric signals. When the light source 162 is lit, the corresponding text area or pattern area on the LED display area can be highlighted, so that the knob assembly 1 can both select a program and have a better display function.

[0065] In some embodiments, the shape of the OLED display area 15 a is not limited and may be rectangular, square, circular, oval, etc.

[0066] For some examples, see Figure 4 , Figure 6 and Fig.12 The size of the OLED display area 15a or the TFT display area along the first direction is greater than or equal to the size along the second direction, and the LED component 16 has a light source 162, which is arranged on at least one side of the OLED component 15 along the second direction.

[0067] The first direction and the second direction intersect, that is, the first direction and the second direction are not parallel. In the embodiment of the present application, the first direction and the second direction are perpendicular to each other as an example for description.

[0068] That is to say, the OLED display area 15a and the light source 162 are arranged along the second direction, and the size of the OLED display area 15a in the first direction can be increased as much as possible to increase the area of ​​the OLED display area 15a. At the same time, the size of the OLED display area 15a in the second direction can be made smaller to avoid the light source 162. In this embodiment, the layout of the OLED display area 15a and the light source 162 is more reasonable, which increases the area of ​​the OLED display area 15a and can increase the total area of ​​the display area.

[0069] In some embodiments, the LED display area is arranged parallel to the first direction.

[0070] By arranging the LED display area parallel to the first direction, the LED display area can be arranged in a horizontal direction, which is more in line with the user's usage habits and improves the user's usage experience. Figure 4 and Figure 6 The knob assembly 1 includes a mounting seat 17 , and the OLED assembly 15 is flat and disposed on a side of the mounting seat 17 facing the window cover 14 .

[0071] The mounting base 17 is used to mount the OLED component 15. Specifically, a mounting space 17a is provided on one side of the mounting base 17 facing the window cover 14.

[0074] The light source 162 is, for example, an LED light source 162 .

[0075] The LED assembly 16 includes a first circuit board 161 and a light source 162 disposed on the first circuit board 161. For example, the light source 162 is electrically soldered to the first circuit board 161, and the first circuit board 161 is electrically connected to the second circuit board 131 through a wire, so that the LED assembly 16 can light up the corresponding light source 162 according to different electrical signals.

[0076] In some embodiments, the LED assembly 16 includes a membrane 21 disposed on the surface of the mounting base 17 , the membrane 21 is provided with a graphic area, and the light source 162 is used to project light to the graphic area.

[0077] The diaphragm 21 is provided with a graphic area, and the specific type of the graphic area is not limited here, for example, it is a text area or a pattern area.

[0078] The portion of the film 21 corresponding to the light source 162 of the LED assembly may be preset with text or patterns. The light source 162 is used to project light to the graphic area. When the light source 162 is turned on, the corresponding text area or pattern area on the film 21 may be highlighted.

[0079] In some embodiments, the mounting base 17 is provided with a light-transmitting area 17 b , and the light source 162 is projected onto the graphic area through the light-transmitting area 17 b .

[0080] The mounting seat 17 is provided with a light-transmitting area 17b, and the light of the light source 162 is projected to the membrane 21 through the light-transmitting area 17b. The light-transmitting area 17b can pass and focus the light of the light source 162, thereby facilitating the light of the light source 162 to be projected to the membrane 21 through the light-transmitting area 17b.

[0081] The light-transmitting areas 17b are arranged on both sides of the installation space 17a along the second direction, wherein the light-transmitting areas 17b on both sides of the installation space 17a along the second direction can both correspond to the graphic areas of the diaphragm 21, or the light-transmitting areas 17b on one side correspond to the graphic areas of the diaphragm 21, and the light-transmitting areas 17b on the other side do not correspond to the graphic areas of the diaphragm 21, and the light-transmitting areas 17b on this side can be used for flashing light passing through the light source 162.

[0082] Exemplarily, the membrane 21 is provided with an escape opening for avoiding the OLED display area 15 a.

[0083] For some examples, see Figure 4 and Figure 7 , the lamp holder 18 is formed with a receiving cavity 18a, and the mounting seat 17 is at least partially received in the receiving cavity 18a. The lamp holder 18 is generally cylindrical, and is formed with a receiving cavity 18a for receiving the mounting seat 17 and the LED assembly 16. That is, by receiving the mounting seat 17 in the receiving cavity 18a of the lamp holder 18, the first circuit board 161 is arranged between the mounting seat 17 and the lamp holder 18 for the mounting seat 17 and the LED assembly 16 to be installed, and at the same time, the LED assembly 16 and the OLED assembly 15 in the mounting seat 17 are protected, thereby improving the reliability of the knob assembly 1.

[0084] For some examples, see Figure 4 , Figure 6 and Figure 7One of the circumferential side wall of the mounting seat 17 and the side wall of the accommodating cavity 18a is provided with a positioning groove 17c, and the other is provided with a positioning rib 18b. The positioning groove 17c cooperates with the positioning rib 18b to position the mounting seat 17 in the circumferential direction.

[0085] For some examples, see Figure 4 The window cover 14 includes a cover plate 141 and a side panel 142 . The side panel 142 is located on a side of the cover plate 141 facing the OLED assembly 15 and extends along an edge of the cover plate 141 . The side panel 142 surrounds the lamp holder 18 and is connected to the lamp holder 18 .

[0086] It should be noted that the ratio of the projection area of ​​the OLED display area 15 a on the window cover 14 to the total area of ​​the window cover 14 refers to the ratio of the projection area of ​​the OLED display area 15 a on the cover plate 141 to the total area of ​​the cover plate 141 .

[0087] The side panel 142 surrounds the circumference of the lamp holder 18 and is connected to the lamp holder 18. The specific connection method is not limited here. For example, one of the side panel 142 and the lamp holder 18 is provided with a buckle 18c, and the other is provided with a slot 142a. The buckle 18c cooperates with the slot 142a to connect the side panel 142 with the lamp holder 18.

[0088] In this way, the window cover 14 is provided with a cover plate 141 and a side panel 142, and the side panel 142 surrounds the periphery of the lamp holder 18 and is connected to the lamp holder 18. While realizing the connection between the window cover 14 and the lamp holder 18, the side panel 142 surrounds the periphery of the lamp holder 18 and can also improve the sealing between the window cover 14 and the lamp holder 18, and to a certain extent can prevent external liquid or air from entering the accommodating cavity 18a of the lamp holder 18 and causing damage to the OLED component 15 and the LED component 16, thereby improving the reliability of the knob assembly 1.

[0089] In addition, by connecting the window cover 14 to the lamp holder 18 , the mounting base 17 and the LED assembly 16 can be clamped therebetween, so as to improve the reliability of the installation of the mounting base 17 and the LED assembly 16 .

[0090] For some examples, see Figure 3 and Figure 4 The knob assembly 1 includes a sealing ring 19 , which extends along an edge of the lamp holder 18 on one side toward the cover plate 141 and is in sealing contact with the cover plate 141 .

[0091] The sealing ring 19 is provided so that the sealing ring 19 is sealingly clamped between the cover plate 141 and the lamp holder 18 to seal the gap between the cover plate 141 and the lamp holder 18 , thereby further improving the sealing between the window cover 14 and the lamp holder 18 .

[0092] The specific structure of the sealing ring 19 is not limited here. Exemplarily, the sealing ring 19 includes a first ring body 191, a second ring body 192, and a connecting side 193 connecting the first ring body 191 and the second ring body 192, wherein the first ring body 191 is sealed and clamped between the cover plate 141 and the lamp holder 18, and the second ring body 192 is sealed and clamped between the side of the mounting base 17 facing away from the cover plate 141 and the lamp holder 18.

[0093] In addition, the connecting side edges 193 are discontinuous side edges, so that the gaps between the discontinuous side edges can avoid the positioning ribs 18b on the side walls of the accommodating cavity 18a.

[0094] In some embodiments, a positioning groove 18d is further provided on the side wall of the accommodating cavity 18a, and at least a portion of the connecting side edge 193 can cooperate with the positioning groove 18d to position the sealing ring 19.

[0095] For some examples, see Figures 3 to 5 The knob ring 11 includes a metal ring 111 and a connecting structure 112 arranged on the metal ring 111. The knob assembly 1 includes a knob base 12, which is connected to the connecting structure 112. The knob base 12 is used to rotate with the knob ring 11 to trigger the electric control assembly 13 to generate an electrical signal.

[0096] The metal ring 111 has a higher density, so the knob assembly 1 can be heavier, giving it a heavy feel and improving the user experience. In addition, the heavy feel is achieved through the weight of the knob assembly 1 itself, without the need for friction damping, thereby reducing the wear of components and improving the service life of the knob assembly 1.

[0097] Exemplarily, the knob base 12 is a plastic part. In some embodiments, the knob base 12 is an integrated plastic part.

[0098] The metal ring 111 and the connection structure 112 may be connected in any manner, such as bonding, welding, etc.

[0099] For example, in some embodiments, the connection structure 112 is a plastic part, the metal ring 111 is a metal part, and the metal ring 111 and the connection structure 112 are injection molded into an integrated structure. For example, during the manufacturing process, after the metal ring 111 is processed, the metal ring 111 is placed in an injection mold, and molten resin is injected into the injection mold. After the mold is opened, the resin is cooled to form the above-mentioned connection structure 112, and the resin and the metal ring 111 are combined together without the need for other fasteners for connection.

[0100] The specific connection method between the connection structure 112 and the knob base 12 is not limited.

[0101] Exemplarily, one of the knob base 12 and the connecting structure 112 is provided with a plurality of snap-in grooves 12a (see Figure 8 ), and the other is provided with a plurality of hooks 112a (see Figure 5 ), a plurality of hooks 112a are arranged along the circumference of the metal ring 111, and the hooks 112a are snapped into the snap-in grooves 12a. For example, in some embodiments, the knob base 12 is provided with a hook 112a, and the connecting structure 112 is provided with a snap-in groove 12a. In other embodiments, the knob base 12 is provided with a snap-in groove 12a, and the connecting structure 112 is provided with a hook 112a.

[0109] The knob assembly 1 is arranged on the housing.

[0110] The electric control component 13 is electrically connected to the control device, that is, signals can be transmitted between the two. The control device is used to select a corresponding control program according to the electrical signal generated by the electric control component 13.

[0111] The control program includes at least one of a washing program, washing parameters, alarm / reminder information, and user-defined information in the APP.

[0112] For example, the user selects the corresponding control program by rotating the knob. Specifically, taking the selection of the washing program as an example, when the user rotates the knob, the electric control component 13 generates different electrical signals at different angles. Different electrical signals correspond to different washing programs. The control device controls the clothing processing device to enter the corresponding washing program according to different electrical signals. At the same time, the OLED component 15 can display corresponding information according to different electrical signals, and the LED component 16 can also light up the corresponding light source 162 according to different electrical signals. The window cover 14 is used to see through the information displayed by the OLED component 15. When the light source 162 is lit, the corresponding text area or pattern area on the LED display area can be highlighted, so that the knob component 1 can select the program and have a better display function.

[0113] For example, see Fig. 9 , Fig.10 and Fig.11 The housing includes a box body and a control panel 2, and the control panel 2 is arranged on the box body. For example, the top side of the front plate of the box body has a vacancy, and the control panel 2 is arranged in the vacancy.

[0114] See also Fig.11 , the control panel 2 is partially recessed toward the inside of the housing to form a recessed cavity 2a, the electric control component 13 is disposed in the recessed cavity 2a, and the knob covers the recessed cavity 2a. In other words, the projection area of ​​the knob on the panel of the control panel 2 covers the projection area of ​​the recessed cavity 2a, and the user can hardly see the recessed cavity 2a.

[0115] It can be connected that the cavity wall of the recessed cavity 2a is provided with a through hole 2b for passing the cable of the electric control component 13.

[0116] It can be understood that by setting the ratio of the projection area of ​​the first display area and the second display area on the window cover 14 to no less than 40% to the total area of ​​the window cover 14, it is beneficial to display more information, thereby reducing the information that needs to be displayed on the control panel 2. As a result, the size of the control panel 2 can be appropriately reduced, thereby improving the aesthetics of the clothing processing device.

[0117] For example, see Figures 9 to 12 , in the projection on the window cover 14, the LED display area 16a is located on the upper side and / or the lower side of the OLED display area 15a.

[0118] That is to say, the LED display area 16a may be located only on the upper side of the OLED display area 15a, or only on the lower side of the OLED display area 15a, or the LED display area 16a may be provided on both the upper side and the lower side of the OLED display area 15a.

[0119] By locating the LED display area 16a on the upper side and / or the lower side of the OLED display area 15a, the graphic area can be arranged in the horizontal direction, which is more in line with the user's usage habits and improves the user's usage experience.
