To solve the above problems, referring to fig. 1, an aspect of the present application proposes a dishwasher, which in an embodiment of the present application includes a body (not shown) and a door assembly 100.

The machine body is provided with a washing cavity and an opening communicated with the washing cavity. The wash chamber may be a chamber in which dishes are placed and the opening may be used for a user to take and place the dishes. The door assembly 100 is mounted on the machine body, and in particular, the door assembly 100 may be openably and closably disposed at an opening of the machine body for opening or closing the opening.

In another aspect of the present application, referring to fig. 1 to 3, a door assembly 100 is provided, and in an embodiment of the present application, the door assembly 100 includes a door 10, an indicator light assembly 30 and a hanging plate 50.

The door 10 may be mounted on the machine body, for example, may be openably and closably disposed at an opening of the machine body for opening or closing the opening. Referring to fig. 4, the door 10 has a thickness direction, and may include a first wall 11, a second wall 13, and a third wall 15, where the first wall 11 is adjacent to the second wall 13, and the third wall 15 is connected to the second wall 13 and is disposed opposite to the first wall 11 in the thickness direction of the door 10. It will be appreciated that the combination of the first wall 11, the second wall 13 and the third wall 15 may have a substantially U-shape overall, which is not limited to this aspect of the application.

Specifically, the surface of the first wall 11 may be oriented in the thickness direction of the door 10, that is, the surface of the first wall 11 may be oriented toward the outside or the inside of the dishwasher, and it should be noted that the outside refers to the side of the door 10 near the user, and the inside refers to the side of the door 10 near the machine body.

The second wall 13 may be provided with a light emitting hole 13a, wherein the light emitting hole 13a may be elongated, for example, may be rectangular or elliptical, or may be short, which is not limited by the present application. The panel of the second wall 13 may be directed to the left or right side of the dishwasher, for example, when the dishwasher is embedded in the mounting slot of the wall cabinet during actual use, the panel of the second wall 13 may be directed to the left or right slot side wall of the mounting slot, so that the light emitted from the light source assembly 33 can be finally projected onto the left or right slot side wall of the mounting slot, that is, the left or right slot side wall may be the projection surface 300 of the light source assembly 33, and the projection surface 300 may be disposed parallel to and opposite to the second wall 13.

The indicator light assembly 30, which may be fixed to the first wall 11 of the door 10, includes a housing 31 and a light source assembly 33. The housing 31 may have a plurality of outer side walls in a shape having a substantially rectangular parallelepiped, square or a combination of a plurality of rectangular shapes, and the shape of the housing 31 is not limited to the present application. The housing 31 may be hollow, and a mounting cavity 31a is formed therein, and the lamp source assembly 33 may be fixed on the housing 31 by being fixed in the mounting cavity 31a, so that the lamp source assembly 33 is protected and hidden by the housing 31. It will be appreciated that in other constructions, the light source assembly 33 may be secured to the outer side wall of the housing 31.

The lamp assembly 33 has a function of emitting light, and the lamp assembly 33 may include a circuit board 331 and a lamp 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 emit light. The housing 31 may be provided with a via hole 31b communicating with the mounting cavity 31a, and the via hole 31b may be penetrated by a wire connected to the circuit board 331. When the light source assembly 33 is fixed on the first wall 11 of the door body 10, the circuit board 331 can be electrically connected with the main control module on the machine body through a wire, so that the main control module of the machine body can output a signal to the circuit board 331 of the indicator light assembly 30 according to the current state of the machine body, and the circuit board 331 drives the light source 333 to emit light rays with corresponding colors, so that the effect of automatically emitting the light rays by the light source 333 is realized.

In particular, the light source 333 may be a single color LED lamp or a multi-color LED lamp. When the light source 333 is a multicolor LED lamp, multiple colors of light can be emitted by combining color matching, for example, when the multicolor LED lamp includes three light beads 3331, the three light beads 3331 can respectively emit light rays of three colors of red, green and blue, and the red, green and blue serve as three primary colors in an optical system, so that the light source 333 can emit light rays of three different colors of red, green and blue, and the light rays of different colors can be adjusted by mixing the light rays of two or three of red, green and blue, so as to emit light rays of different colors. Of course, the multicolor LED lamp may further include four lamp beads 3331, and the four lamp beads 3331 may respectively emit light of four colors of red, green, blue and white, which is not limited in the present application.

So, when the light source 333 is a multicolor LED light, more light rays with different colors can be emitted to finally present display light spots with different colors, so that the indicator light assembly 30 can represent more working states of the machine body, and a user can select the display colors of the display light spots according to own preference, thereby meeting the demands of different users. The following description will further illustrate the present application by taking the light source 333 as an example of a multicolor LED lamp.

The hanging plate 50 may be shaped to match the shape of the door body 10, and may be connected to the surface of the third wall body 15 facing away from the first wall body 11, so as to provide a shielding effect on the door body 10, improve the external aesthetic property of the door body assembly 100, and provide a certain protection effect on the door body 10.

The light source 333 has a light emitting direction, and the light emitting direction may be consistent with the direction of the light emitting hole 13a, so that the light emitted by the light source 333 can directly pass through the light emitting hole 13a and can be vertically projected onto the projection surface 300. Therefore, the light emitting hole 13a is formed in the second wall 13, and the housing 31 is fixed on the first wall 11, so that the light emitted by the light source 333 fixed on the housing 31 can be concentrated and vertically projected onto the projection surface 300 which is parallel to and opposite to the second wall 13 after directly passing through the light emitting hole 13a, so that part of the light is prevented from being projected onto an area outside the projection surface 300, and the light can be more concentrated and projected onto the projection surface 300, so that the overall brightness of the display light spot displayed on the projection surface 300 is more uniform, the display effect of the display light spot displayed by the indicator light assembly 30 is improved, and the observation of a user is facilitated.

In an embodiment, referring to fig. 5 to 6, the housing 31 includes a light-emitting wall 311 facing the second wall 13, and a light-emitting portion 3111 is formed on the light-emitting wall 311. The housing 31 may include a first casing 313 and a second casing 315, where the first casing 313 and the second casing 315 are connected and cooperate to form a mounting cavity 31a, and a wire passing hole 31b is formed between the first casing 313 and the second casing 315. Specifically, one of the first housing 313 and the second housing 315 may be provided with the light-emitting wall 311 and the light-emitting portion 3111, and the following description will further explain the present application by taking the case where the first housing 313 is provided with the light-emitting wall 311 and the light-emitting portion 3111.

The material of the first housing 313 may be a transparent plastic material, for example, suitable exemplary materials that may be used include, but are not limited to, PMMA (Polymethyl Methacrylate ) material, PC (Polycarbonate) material, ABS (Acrylonitrile Butadiene STYRENE PLASTIC, acrylonitrile butadiene styrene) material. The material of the second housing 315 may be non-transparent, so that the light emitted from the light source 333 is only transmitted through the first housing 313, which is not limited in the present application.

The light-emitting portion 3111 may include a light-incident surface 3111a and a light-emitting surface 3111b, the light-emitting surface 3111b faces the light-emitting hole 13a, and the direction of the light-emitting surface 3111b is consistent with the direction of the light-emitting hole 13a, so that the light emitted by the light source 333 is vertically directed to the projection surface 300 after passing through the light-incident surface 3111a, the light-emitting surface 3111b and the light-emitting hole 13a in sequence. In this way, the housing 31 may be provided with the light-emitting wall 311, and the light-emitting portion 3111 is formed on the light-emitting wall 311, so that the light emitted by the light source 333 may directly pass through the light-emitting surface 3111b of the light-emitting portion 3111 on the light-emitting wall 311, so as to enable the light to be vertically projected onto the projection surface 300. In this way, the relative regularity of the structure of the housing 31 can also be achieved, so that the housing 31 can be produced and manufactured by a workshop.

Further, the light emergent wall 311 may include a first surface 3113 and a second surface 3115 disposed opposite to each other, where the first surface 3113 faces the light emergent hole 13a, i.e. the first surface 3113 is closer to the projection surface 300 than the second surface 3115. The light-emitting portion 3111 protrudes from the first surface 3113 and is fitted into the light-emitting hole 13 a. In this way, the light emitted by the light source 333 is concentrated and emitted to the projection surface 300 by the light emitting portion 3111 embedded in the light emitting hole 13a, so that the light is more concentrated, the brightness of the display light spot presented by the projection surface 300 is more uniform, the display effect of the display light spot presented by the indicator light assembly 30 is further improved, and the second wall 13 can shield the portion of the light emitting wall 11 outside the light emitting portion 3111, so that only the light passing through the light emitting portion 3111 can be emitted to the projection surface 300.

The light incident surface 3111a is sunken toward the light emergent hole 13a compared with the second surface 3115, so that a light emergent groove 311a is formed at a side of the light emergent wall 311 located on the second surface 3115, and an orthographic projection of the light source 333 toward the second surface 3115 falls within the region of the light emergent groove 311 a. Under such setting, the light that the lamp source 333 sent can gather in the light-emitting slot 311a, and then directly pass out the light-emitting hole 13a through the light-emitting part 3111 to concentrate and vertically project on the projection surface 300, so that the divergence of the light can be reduced, the utilization ratio of the light that the lamp source 333 sent is improved, and thus the brightness of the display facula that the light presents on the projection surface 300 can be improved, and the display effect of the display facula is further improved.

In order to make the display light spot of the light source 333 displayed on the projection surface 300 more convenient for the user to observe, the present application sets the shape of the light emergent portion 3111 and the shape of the light emergent hole 13a to be adapted, that is, when the light emergent hole 13a is long, the light emergent portion 3111 is long. Referring to fig. 7, the light source 333 may include a plurality of light beads 3331 disposed at intervals, and the plurality of light beads 3331 may be arranged at intervals along the extending direction of the light emitting portion 3111. Thus, the light emitted by the plurality of light beads 3331 may be distributed along the length of the light emergent portion 3111, and may be directed to the light emergent portion 3111, so that the display light spot finally presented on the projection surface 300 may be also in a long strip shape, and the display effect of light belt luminescence is similarly presented.

In one structural form, referring to fig. 4, the light-emitting surface 3111b of the present application is not protruding from the outer wall surface of the second wall 13 facing away from the light source assembly 33. With this arrangement, the entire light emergent portion 3111 can be accommodated in the light emergent hole 13a of the second wall body 13, and compared with the structure in which the light emergent surface 3111b protrudes from the outer wall surface of the second wall surface, the light emergent portion 3111 can be prevented from being touched by the outside, for example, the user or the wall of the installation groove touches the light emergent portion 3111, and damage to the light emergent portion 3111 is avoided. Therefore, the second wall 13 of the present embodiment can protect the light emitting portion 3111, and thus the service life of the indicator lamp assembly 30 can be prolonged.

The distance between the light source 333 of the light source assembly 33 and the light incident surface 3111a of the light emergent portion 3111 is set to be 5mm to 15 mm, so that the brightness of the display light spot presented on the projection surface 300 can be uniform, and the overall size of the indicator light assembly 30 can be reduced. If the distance between the light source 333 and the light incident surface 3111a is less than 5mm, the distance between the light source 333 and the light incident surface 3111a is too short, so that the display range of the display light spot on the projection surface 300 is too large, resulting in uneven brightness of the whole display light spot and affecting the display effect. If the distance between the light source 333 and the light incident surface 3111a is greater than 15 mm, the distance between the light source 333 and the light incident surface 3111a is too long, so that the distance between the light source 333 and the projection surface 300 is too long, and finally the brightness of the display light spot displayed on the projection surface 300 is low, which is inconvenient for the user to observe, and further, the volume of the indicator light assembly 30 is increased, which is not beneficial to the miniaturization of the indicator light assembly 30. The distance between the light source 333 and the light incident surface 3111a may be specifically set to 5mm, 8mm, 10 mm, 12 mm, 15 mm, or the like, which is not limited by the present application.

In order to further improve the luminance uniformity of the display light spot, a plurality of light diffusion particles (not shown) are dispersed in the light emitting portion 3111 of the present application. Since the light-emitting portion 3111 is provided with a plurality of light-diffusing particles, light entering the light-emitting portion 3111 can be diffused, so that the brightness of the display flare can be more uniform, and the display effect of the display flare can be further improved. When the first housing 313 is made of transparent plastic, light diffusion powder may be added to the plastic material during the actual injection molding process, and then the plastic material with the light diffusion powder may be injected into a plastic mold to perform injection molding, so that a plurality of light diffusion particles are dispersed in the light outlet 3111 of the manufactured first housing 313.

In the above, the indication lamp assembly 30 of the door body assembly 100 of the present application is described in terms of the structural cooperation between the door body 10 and the indication lamp assembly 30, and the advantage of displaying light spots with better display effect can be presented on the projection surface 300. Based on this, the connection between the first housing 313 and the second housing 315 according to the present application may be configured as a snap-fit connection, based on the angle that facilitates the assembly and disassembly of the first housing 313 and the second housing 315. Specifically, a first buckle may be disposed on the outer side of the first housing 313, a first clamping groove is disposed on the outer side of the second housing 315, and the first housing 313 and the second housing 315 are buckled and connected through the clamping fit of the first buckle and the second clamping groove, so that in the actual disassembly and assembly process, the operation is convenient, and a worker or a user is convenient to maintain the lamp source assembly 33 fixed in the installation cavity 31 a. On the basis, the application can further be provided with a first limiting part on the outer side of the first housing 313, and the first limiting part is arranged adjacent to the first buckle, so that when the first buckle is clamped in the first clamping groove, the first limiting part can limit the structure of the second housing 315 with the first clamping groove by stopping, thereby avoiding the first buckle from separating from the first clamping groove and improving the connection firmness of the first housing 313 and the second housing 315. Of course, in other connection forms, the first housing 313 and the second housing 315 may be connected by a screw connection, a magnetic connection, or an adhesive connection, etc., and the specific connection form of the first housing 313 and the second housing 315 is not specifically limited in the present application.

In some structural forms, referring to fig. 7 to 8, a winding portion 3131 is disposed on an outer side of the first casing 313 of the housing 31, wherein, referring to fig. 5, the winding portion 3131 is disposed adjacent to the via hole 31 b. If the length of the wire is too long, the wire is messy, and part of the wire body of the wire sags, which affects the electrical safety and the aesthetic property of the indicator lamp assembly 30. Therefore, under the arrangement of the winding portion 3131, a portion of the wire body of the wire can be wound around the winding portion 3131, so as to avoid the phenomenon that the wire is scattered and sagged. Of course, in other configurations, the winding portion 3131 may be disposed on the second casing 315 of the housing 31.

Specifically, the winding portion 3131 may include a winding post and a limiting post, where opposite ends of the winding post are respectively connected to an outer side of the first housing 313 of the housing 31 and the limiting post, and an extending direction of the winding post and an extending direction of the limiting post have an included angle, where the winding post may allow a portion of a wire body of the wire to be wound, and the limiting post may stop the wire body wound on the winding post in the wire, so as to prevent the wire body from falling off.

In an embodiment, the first cover 313 of the housing 31 is provided with a positioning post 3133, the circuit board 331 is provided with a positioning hole 3311a, and the positioning post 3133 is in plug-fit with the positioning hole 3311 a. In this way, the circuit board 331 can be precisely fixed in the mounting cavity 31a by the positioning matching manner of the positioning posts 3133 and the positioning holes 3311a, that is, the position of the light source 333 mounted on the circuit board 331 in the mounting cavity 31a is precise, so as to achieve that light can be vertically projected onto the projection surface 300. Meanwhile, the positioning column 3133 can function to support the circuit board 331 so that the circuit board 331 can be fixed in the mounting cavity 31 a.

Further, a stop rib is disposed on the second casing 315 of the housing 31, and the stop rib is used for abutting against the circuit board 331 to limit the circuit board 331 from moving relative to the positioning column 3133 and separating from the positioning column 3133. With this arrangement, the stability of the circuit board 331 fixed in the mounting chamber 31a can be further improved, and the circuit board 331 can be prevented from being deviated from the positioning column 3133 and falling.

In an embodiment, referring to fig. 7 to 8, the first cover 313 of the housing 31 is detachably and fixedly connected to the first wall 11. Under such setting, when the structure of the indicator light assembly 30 needs to be maintained, the worker can detach the housing 31 from the first wall 11, and the operation is convenient. In one embodiment, the first cover 313 of the housing 31 and the first wall 11 may be fastened together, and in other embodiments, the first cover 313 of the housing 31 and the first wall 11 may be screwed together or magnetically connected together.

Further, when the first cover 313 of the housing 31 and the first wall 11 are in a fastening connection, specifically, the present application may be that a slide button 3135 is disposed on the outer side of the first cover 313 of the housing 31, the first wall 11 is provided with a sliding slot 11a, and the slide button 3135 is adapted to be connected with the sliding slot 11a, so that the first housing 31 of the housing 31 can be fixedly connected to the first wall 11. Under the cooperation of the slide button 3135 and the chute 11a, the casing 31 can be fixed on the first wall body 11, and the structure is simple, and the disassembly and assembly are quick.

Specifically, the slider 3135 includes an elastic arm and a fastening portion, one end of the elastic arm is connected to the outer side of the first housing 313 of the housing 31, and the other end of the elastic arm is connected to the fastening portion, and the elastic arm can be elastically deformed, so that the fastening portion is fastened in the chute 11a. Therefore, the elastic arm can be driven to elastically deform so that the buckling part is close to or far away from the sliding groove 11a, and the buckling part is clamped or separated from the sliding groove 11a. The sliding groove 11a may be formed through, so that the buckling part can completely extend into the sliding groove 11a when being clamped into the sliding groove 11a, the connection is more firm, and the loosening is not easy to occur. In addition, the first guiding surface 3135a is formed on the surface of the buckling part, so that the buckling part is matched with the guiding of the groove side wall of the chute 11a through the first guiding surface 3135a in the process of being clamped into the chute 11a, the connection process is smoother, and the operation of workers or users is facilitated.

In one structural form, referring to fig. 2, the first wall 11, the second wall 13, and the third wall 15 of the door 10 may cooperate to define a limiting slot 10a, and the housing 31 may be embedded in the limiting slot 10 a. In the actual assembly process, the limiting groove 10a may have a notch, and the housing 31 may be assembled into the limiting groove 10a through the notch, and then the housing 31 may be fixedly embedded into the limiting groove 10a through the cooperation of the slider 3135 and the sliding groove 11 a.

In this way, the protection of the case 31 can be achieved by the first wall 11, the second wall 13, and the third wall 15. Moreover, when the housing 31 is embedded in the limiting groove 10a, the housing 31 can be limited by the three components, so that the housing 31 is prevented from moving, and the position is prevented from shifting, so that the light emitted by the light source 333 can directly pass through the light emitting hole 13a and can be vertically projected onto the projection surface 300.

Further, the wall surface of the third wall body 15 facing the first wall body 11 is further provided with a stopping portion 17 in a protruding manner, and the stopping portion 17 abuts against one side of the housing 31 away from the second wall body 13, so as to stop the housing 31 in a direction in which the indicator light assembly 30 is released from the limiting groove 10 a. It is understood that the stop portion 17 may be disposed adjacent to the notch of the limiting groove 10a, and have a second guiding surface 171 and a limiting surface 173 disposed at an included angle, and when the indicator light assembly 30 moves in the direction of being embedded in the limiting groove 10a, the second guiding surface 171 can be in guiding engagement with the housing 31, so that the housing 31 is more smoothly embedded in the limiting groove 10 a. When the indicator light assembly 30 is located in the limit groove 10a, the limit surface 173 can stop the housing 31 in the direction in which the indicator light assembly 30 is released from the limit groove 10a, so as to prevent the housing 31 from being released from the limit groove 10a, and thus the housing 31 can be more firmly embedded in the limit groove 10a, and the release is avoided.
