[0038] The achievement of objectives, functional features, and advantages of the present disclosure will be further explained with reference to the accompanying drawings in conjunction with the embodiments.DETAILED DESCRIPTION

[0039] To make the purpose, technical solutions, and advantages of the present disclosure clearer, the following sections will provide a detailed description of the embodiments of the present disclosure in conjunction with the accompanying drawings.

[0040] In the following description, unless otherwise indicated, the same reference numerals refer to the same or similar elements in different drawings. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0041] In the description of the present disclosure, it is understood that terms such as "first", "second", etc. are solely for descriptive purposes and should not be understood as indicating or implying relative importance. For those skilled in the art, the specific meanings of the above terms in the present disclosure may be understood based on the specific circumstances. Furthermore, unless otherwise specified in the description of the present disclosure, "multiple" refers to two or more. "And / or" describes a relationship between associated objects, indicating that three relationships may exist, for example, A and / or B may indicate: A exists alone, A and B exist together, or B exists alone. The character " / " generally indicates that the associated objects before and after it are in an "or" relationship.

[0042] Unless otherwise defined, all technical and scientific terms mentioned in this specification have the same meanings as those generally understood by those skilled in the art. The terms mentioned in this specification are intended solely to describe specific embodiments and are not intended to limit the scope of the present disclosure. The term "and / or" used herein includes any one and all combinations of one or more of the listed items.

[0043] There are various types of household appliances, including, e.g., dishwashers, vegetable washers, disinfection cabinets, etc. Some household appliances are equipped with indicator lights. The indicator lights may be configured to indicate a working state of an electrical equipment. For example, when the household appliance is a dishwasher, information displayed by a display light spot projected by the indicator light may represent a working state of a body of the dishwasher, such as operation, pause, and the like.

[0044] When the dishwasher is embedded in a mounting groove of a wall cabinet, the indicator light may be configured to project laterally, and a groove side wall of the mounting groove may be served as a projection surface.

[0045] However, in an exemplary technology, a display effect of the display light spot, which may be projected by the laterally-projecting indicator light on the projection surface, may be poor. The inventors of the present disclosure have found that since a light emitting direction of the laterally-projecting indicator light may be inclined along a direction outside the mounting groove, part of the light emitted by the indicator light may be projected outside an illuminated surface, resulting in a poor display effect of the display light spot projected by the indicator light.

[0046] To solve the above technical problems, as shown in FIG. 1, a dishwasher may be provided according to an aspect of the present disclosure. In the embodiments of the present disclosure, the dishwasher may include a body (not shown) and a door assembly 100.

[0047] A washing cavity and an opening may be defined on the body, and the opening may be in communication with the washing cavity. The washing cavity may be a cavity configured to place tableware. The opening may be configured to allow the user to take and place the tableware. The door assembly 100 may be mounted on the body. In some embodiments, the door assembly 100 may be arranged at the opening of the body in an openable and closable manner to open or close the opening.

[0048] According to another aspect of the present disclosure, a door assembly 100 may be provided by some embodiments of the present disclosure. As shown in FIGS. 1 to 3, in the embodiments of the present disclosure, the door assembly 100 may include a door 10, an indicator light assembly 30, and a hanging plate 50.

[0049] The door 10 may be mounted on the body. In some embodiments, the door 10 may be arranged at the opening of the body in the openable and closable manner to open or close the opening. As shown in FIG. 4, the door 10 may have a thickness direction. The door 10 may include a first wall body 11, a second wall body 13, and a third wall body 15. The first wall body 11 may be adjacent to the second wall body 13. The third wall body 15 may be connected to the second wall body 13. The third wall body 15 may be arranged opposite to and spaced from the first wall body 11 in the thickness direction of the door 10. It may be understood that a shape may be approximately U-shaped as a whole through a combination of the first wall body 11, the second wall body 13, and the third wall body 15, which may be not limited herein.

[0050] In some embodiments, a plate surface of the first wall body 11 may face the same direction as the thickness direction of the door 10, that is, the plate surface of the first wall body 11 may face an outer side or an inner side of the dishwasher. It should be noted that "outer side" herein may be referred to a side of the door 10 close to a user, and "inner side" herein may be referred to a side of the door 10 close to the body.

[0051] A light emitting hole 13a may be defined on the second wall body 13, and the light emitting hole 13a may be in a long strip shape, such as a rectangular shape or an elliptical shape. Of course, the light emitting hole 13a may also be in a short strip shape, which may be not limited herein. A plate surface of the second wall body 13 may face a left side or a right side of the dishwasher. In some embodiments, during an actual usage process, when the dishwasher is embedded in a mounting groove of a wall cabinet, the plate surface of the second wall body 13 may face a left groove side wall or a right groove side wall of the mounting groove, such that light emitted by the light source assembly 33 may be finally projected onto the left groove side wall or the right groove side wall of the mounting groove. That is, the left groove side wall or the right groove side wall may be a projection surface 300 of the light source assembly 33. In addition, the projection surface 300 may be parallel to and opposite to the second wall body 13.

[0052] The indicator light assembly 30 may be fixed on the first wall body 11 of the door 10. The indicator light assembly 30 may include a housing 31 and a light source assembly 33. The housing 31 may have an outline approximately in a shape of a cuboid, a cube, or a shape formed by a combination of multiple rectangles, thereby having multiple outer side walls. A shape of the housing 31 may be not limited herein. The housing 31 may be hollow inside. A mounting cavity 31a may be defined by the housing 31. The light source assembly 33 may be fixed in the mounting cavity 31a to be fixed on the housing 31, such that it may be possible to protect and hide the light source assembly 33 through the housing 31. It may be understood that in other structural forms, the light source assembly 33 may be fixed on an outer side wall of the housing 31.

[0053] The light source assembly 33 may have a function of emitting light. The light source assembly 33 may include a circuit board 331 and a light source 333 mounted on the circuit board 331. The circuit board 331 may be fixed to the housing 31, that is, the circuit board 331 may be fixed in the mounting cavity 31a, and the light source 333 may be configured to emit light. a wire hole 31b may be defined on the housing 31 and in communication with the mounting cavity 31a. The wire hole 31b may be configured to enable / allow a wire connected to the circuit board 331 to pass through. When the light source assembly 33 is fixed on the first wall body 11 of the door 10, the circuit board 331 may be electrically connected to a central control module on the body through the wire. In this way, the central control module of the body may be configured to output a signal to the circuit board 331 of the indicator light assembly 30 according to a current state of the body, and the circuit board 331 may be configured to drive the light source 333 to emit light of a corresponding color, such that it may be possible realize an automatic light emission effect of the light source 333.

[0054] In some embodiments, the light source 333 may be a monochromatic light emitting diode (LED) lamp or a multi-color LED lamp. When the light source 333 is the multi-color LED lamp, the light source 333 may emit light of multiple colors by combining and tuning colors. In some embodiments, when the multi-color LED lamp includes three lamp beads 3331, the three lamp beads 3331 may emit red light, green light, and blue light, respectively. Since red, green, and blue are three primary colors in an optical system, it may enable the light source 333 to emit the red light, the green light, and the blue light, and light of different colors may be generated by mixing light emitted by two or three of the red light, the green light, and the blue light, and tuning light intensity of the light of different colors. Of course, the multi-color LED lamp may also include four lamp beads 3331, and the four lamp beads 3331 may emit the red light, the green light, the blue light, and white light, respectively, which may be not limited herein.

[0055] In this way, when the light source 333 is the multi-color LED lamp, the light source 333 may emit light of more different colors, such that it may be possible to finally present display light spots of multiple different colors, thereby enabling the indicator light assembly 30 to represent more working states of the body. In addition, the user may also select a display color of the display light spot according to his / her own preference, such that it may be possible to meet the needs of different users. The following content will further illustrate the content of some embodiments of the present disclosure by taking the light source 333 as the multi-color LED lamp as an example.

[0056] A shape of the hanging plate 50 may fit with a shape of the door 10. The hanging plate 50 may be connected to a surface of the third wall body 15 away from the first wall body 11, such that it may be possible to shield the door 10, thereby improving an external appearance of the door assembly 100, and providing a certain degree of protection to the door 10.

[0057] The light source 333 may have a light emitting direction, and the light emitting direction may be consistent with an orientation of the light emitting hole 13a, such that light emitted by the light source 333 may pass directly through the light emitting hole 13a and may be vertically projected onto the projection surface 300. In this way, in the embodiments of the present disclosure, by defining the light emitting hole 13a on the second wall body 13 and fixing the housing 31 on the first wall body 11, the light emitted by the light source 333 fixed on the housing 31 may pass directly through the light emitting hole 13a, and the light may be concentrated and vertically projected onto the projection surface 300 that may be parallel to and opposite to the second wall body 13. In addition, it may be possible to prevent part of the light from projecting to a region outside the projection surface 300, such that the light may be more concentratedly projected onto the projection surface 300. Therefore, an overall brightness of the display light spot presented / displayed on the projection surface 300 may be more uniform, such that the display effect of the display light spot presented by the indicator light assembly 30 may be improved, thereby making it more convenient for the user to observe.

[0058] In some embodiments, as shown in FIGS. 5 to 6, the housing 31 may include a light emitting wall 311 facing the second wall body 13. A light emitting portion 3111 may be arranged on the light emitting wall 311. The housing 31 may include a first cover shell 313 and a second cover shell 315. The first cover shell 313 may be connected to the second cover shell 315 to define the mounting cavity 31a. In addition, a wire hole 31b may be defined between the first cover shell 313 and the second cover shell 315. In some embodiments, the light emitting wall 311 and the light emitting portion 3111 may be arranged on one of the first cover shell 313 and the second cover shell 315. The following content will further illustrate the content of some embodiments of the present disclosure by taking a case where the light emitting wall 311 and the light emitting portion 3111 may be arranged on the first cover shell 313 as an example.

[0059] A material of the first cover shell 313 may be a transparent plastic material. In some embodiments, a suitable exemplary material which may be used may include, but is not limited to, a polymethyl methacrylate (PMMA) material, a polycarbonate (PC) material, and an acrylonitrile butadiene styrene plastic (ABS) material. A material of the second cover shell 315 may be an opaque material, such that the light emitted by the light source 333 may only pass through the first cover shell 313, which may be not limited herein.

[0060] The light emitting portion 3111 may include a light incident surface 3111a and a light emitting surface 3111b. The light emitting surface 3111b may face the light emitting hole 13a, and a direction of the light emitting surface 3111b may be consistent with the orientation of the light emitting hole 13a, such that the light emitted by the light source 333 may pass through the light incident surface 3111a, the light emitting surface 3111b, and the light emitting hole 13a in sequence, and may be projected vertically onto the projection surface 300. With the above-mentioned arrangement, by arranging the light emitting wall 311 on the housing 31 and arranging the light emitting portion 3111 on the light emitting wall 311, it may be possible to allow the light emitted by the light source 333 to directly pass through the light emitting surface 3111b of the light emitting portion 3111 on the light emitting wall 311, thereby enabling the light to be vertically projected onto the projection surface 300. In this way, a structure of the housing 31 may also be relatively regular, which may facilitate the production and manufacture of the housing 31 in a workshop.

[0061] In some embodiments, the light emitting wall 311 may include a first surface 3113 and a second surface 3115 that may be opposite to each other. The first surface 3113 may face the light emitting hole 13a. That is, the first surface 3113 may be closer to the projection surface 300 than the second surface 3115. The light emitting portion 3111 may protrude from the first surface 3113 and may be embedded in the light emitting hole 13a. In this way, the light emitted by the light source 333 may be concentrated and projected towards the projection surface 300 through the light-emitting portion 3111 embedded in the light-emitting hole 13a, such that the light may be more concentrated. Therefore, the brightness of the display light spot presented by the light on the projection surface 300 may be more uniform, such that the display effect of the display light spot presented by the indicator light assembly 30 may be further improved. In addition, a part of the light emitting wall 11 except the light emitting portion 3111may be blocked by the second wall body 13, such that only the light passing through the light emitting portion 3111 may be projected onto the projection surface 300.

[0062] The light incident surface 3111a may be recessed toward the orientation of the light emitting hole 13a relative to the second surface 3115, such that a light emitting groove 311a may be defined at a side of the light emitting wall 311 where the second surface 3115 may be disposed. An orthographic projection of the light source 333 toward the second surface 3115 may be / fall within a region of the light emitting groove 311a. With the above-mentioned arrangement, the light emitted by the light source 333 may be concentrated in the light emitting groove 311a, and pass directly through the light emitting hole 13a through the light emitting portion 3111, such that the light may be concentrated and vertically projected onto the projection surface 300. Therefore, it may be possible to reduce the divergence of the light, and improve the utilization rate of the light emitted by the light source 333, such that it may be possible to improve the brightness of the display light spot presented by the light on the projection surface 300, thereby further improving the display effect of the display light spot.

[0063] In some embodiments of the present disclosure, a shape of the light emitting portion 3111 may fit with a shape of the light emitting hole 13a, such that it may be possible to enable the display light spot presented by the light source 333 on the projection surface 300 to be more convenient for the user to observe. That is, when the light emitting hole 13a is strip-shaped, the light emitting portion 3111 may also be strip-shaped. As shown in FIG. 7, the light source 333 may include a plurality of lamp beads 3331 arranged at intervals. The plurality of lamp beads 3331 may be arranged at intervals along a length extension direction of the light emitting portion 3111. In this way, the light emitted by the plurality of lamp beads 3331 may be approximately arranged along a length of the light emitting portion 3111, and may be directed to the light emitting portion 3111, such that the display light spot finally presented on the projection surface 300 may also be strip-shaped, which may be similar to the display effect of light emission from a light strip. Compared with a single dot-shaped display light spot, a strip-shaped display light spot may have a relatively wider display range, such that it may be more convenient for the user to observe, thereby further improving the user experience.

[0064] In a structural form, as shown in FIG. 4, in some embodiments of the present disclosure, the light emitting surface 3111b may not protrude beyond an outer wall surface of the second wall body 13 that may be opposite to the light source assembly 33. With the above-mentioned arrangement, the entire light emitting portion 3111 may be accommodated in the light emitting hole 13a of the second wall body 13. Compared with a structural form where the light emitting surface 3111b may protrude beyond the outer wall surface of the second wall body, it may be possible to prevent the light emitting portion 3111 from being touched by the outside in some embodiments of the present disclosure. In some embodiments, when the light emitting portion 3111 is touched by the user or a groove wall of the mounting groove, the light emitting portion 3111 may be damaged. Therefore, the structural form in the embodiments of the present disclosure may providing protection to the light emitting portion 3111 through the second wall body 13, such that it may be possible to extend the service life of the indicator light assembly 30.

[0065] As shown in FIG. 6, in some embodiments, a distance L between the light source 333 of the light source assembly 33 and the light incident surface 3111a of the light emitting portion 3111 may be in a range from 5 mm to 15 mm (i.e., 5 mm - 15 mm) in some embodiments of the present disclosure. In this way, the brightness of the display light spot presented on the projection surface 300 may be uniform, and an overall volume of the indicator light assembly 30 may be reduced. When the distance L between the light source 333 and the light incident surface 3111a may be less than 5 mm, the distance L between the light source 333 and the light incident surface 3111a may be too short, which may cause a display range of the display light spot on the projection surface 300 to be too large, resulting in uneven overall brightness of the display light spot and affecting the display effect. When the distance L between the light source 333 and the light incident surface 3111a may be greater than 15 mm, the distance L between the light source 333 and the light incident surface 3111a may be too long, which may cause the distance L from the light source 333 to the projection surface 300 to be too long. Therefore, the brightness of the display light spot finally presented on the projection surface 300 may be low, which may be not convenient for the user to observe. In addition, the volume of the indicator light assembly 30 may also be increased, which may be not conducive to realizing the miniaturization of the indicator light assembly 30. In some embodiments, the distance L between the light source 333 and the light incident surface 3111a may be 5 mm, 8 mm, 10 mm, 12 mm, or 15 mm, etc., which may be not limited herein.

[0066] As shown in FIG. 5, in some embodiments, a plurality of light diffusion particles 3112 may be scattered in the light emitting portion 3111, such that it may be possible to further improve the brightness uniformity of the display light spot.
