Description

Technical Field

[0001] Embodiments of the present application relate to home appliance technologies, and in particular, to a dishwasher. Background Art

[0002] With the improvement of living standards, people have higher and higher requirements for the quality of life, and household dishwashers have increasingly entered people's lives in recent years.

[0003] In related technologies, a dishwasher includes a cabinet, and at least two spaced-apart lighting devices are arranged inside the cabinet, and the main optical axis of the lighting device is perpendicular to the ground.

[0004] However, the cost of the lighting device is relatively high. Utility Model Content

[0005] Embodiments of the present application provide a dishwasher with a relatively low cost.

[0006] In a first aspect, embodiments of the present application provide a dishwasher, including:

[0007] A cabinet, which is configured with a receiving cavity;

[0008] A bowl basket, which is located in the receiving cavity and is slidably connected to the cabinet;

[0009] A lighting device, which is located at the top of the receiving cavity and is close to one end of the cabinet along the width direction. The lighting device includes:

[0010] A lamp holder, which is configured with an installation cavity, and the bottom wall of the installation cavity is configured with a lens structure;

[0011] A light source structure, which includes:

[0012] A circuit board, which is located in the installation cavity, and the extending plane of the circuit board has a first included angle with the ground;

[0013] A lamp bead, which is connected to the circuit board and is opposite to the lens structure.

[0014] Based on the principle that the farther away from the lighting device along the direction of the main optical axis, the larger the illumination range of the lighting device, in this application, the lighting device is arranged at the top of the box body, close to one end of the box body along the width direction. By setting the lamp holder and the light source structure, the circuit board of the light source structure is located in the installation cavity of the lamp holder, and the extending plane of the circuit board has a first included angle with the ground. The lamp beads of the light source structure are connected to the circuit board, and the lamp beads are opposite to the lens structure on the bottom wall of the lamp holder, so that the main optical axis of the lighting device has a second included angle with the ground, and the second included angle is not equal to 90 degrees. Thus, the distance from the inner wall of the box body to the lighting device along the direction of the main optical axis can be changed, and the illumination range of the lighting device can be changed. Therefore, the inside of the box body can be illuminated by using one lighting device, the number of lighting devices is reduced, and the cost can be reduced.

[0015] In some embodiments of the dishwasher, the first included angle is greater than 30 degrees and less than 40 degrees.

[0016] When the height of the accommodation cavity is fixed and the light-emitting angle of the lighting device is fixed, when the lighting device is close to the first end of the box body along the width direction, the first included angle is less than 30 degrees, the inclination angle is small, and the brightness of the bottom area at the second end of the box body along the width direction is small. When the first included angle is greater than 40 degrees, the inclination angle is large, and the brightness of the bottom area at the first end of the box body along the width direction is small.

[0017] In some embodiments of the dishwasher, the bottom wall of the installation cavity is configured with a guiding inclined surface that abuts against the circuit board, and the extending plane of the guiding inclined surface has a first included angle with the ground;

[0018] One side of the circuit board facing the lamp beads abuts against the guiding inclined surface.

[0019] In this way, when installing the light source structure, it is only necessary to place the side of the circuit board facing the lamp beads on the guiding inclined surface, and the installation is relatively simple and the installation efficiency is high.

[0020] In some embodiments of the dishwasher, the circuit board is configured with a first positioning portion, and the guiding inclined surface is configured with a second positioning portion. The second positioning portion is matched with the first positioning portion, and the second positioning portion is connected to the first positioning portion.

[0021] In this way, the installation position of the light source structure can be restricted.

[0022] In some embodiments of the dishwasher, the first positioning portion includes at least one positioning protrusion, the second positioning portion includes at least one positioning cavity, at least one positioning protrusion is arranged in one-to-one correspondence with at least one positioning cavity, and the positioning protrusion is inserted into the corresponding positioning cavity.

[0023] In this way, compared with adding positioning protrusions to the circuit board, the processing difficulty of setting the positioning cavity by the method of punching and removing materials is smaller.

[0024] In some embodiments of the dishwasher, the lamp beads are surface-mounted lamp beads;

[0025] The lens structure is a convex lens structure.

[0026] In this way, the light-emitting angle of the surface-mounted lamp beads is relatively large, and the convex lens structure is used for condensing light, which is beneficial to improving the brightness of the light.

[0027] In some embodiments of the dishwasher, the lamp holder includes;

[0028] A base, the bottom wall of the base is constructed with a lens structure, and the lens structure is integrally provided with the base;

[0029] A cover plate, the cover plate is covered on the top of the base, and the cover plate is detachably connected to the base.

[0030] In this way, the lens structure and the base can be integrally formed by injection molding, and the processing efficiency is relatively high.

[0031] In some embodiments of the dishwasher, a limiting portion is constructed on the inner top wall of the cover plate. When the cover plate is connected to the base, the limiting portion abuts against the circuit board.

[0032] In this way, the position of the circuit board can be limited.

[0033] In some embodiments of the dishwasher, the cabinet includes;

[0034] A housing;

[0035] An inner liner, the inner liner is located inside the housing, the inner liner is constructed with a receiving cavity, one side of the inner liner in the depth direction is constructed with a first opening, the first opening communicates with the receiving cavity, the top of the inner liner is constructed with a second opening, the second opening communicates with the receiving cavity, the second opening is close to the edge of the inner liner in the depth direction and close to the first opening;

[0036] The lighting device is connected to the outer top wall of the inner liner, and the lens structure is opposite to the second opening.

[0037] In this way, after the user pulls the bowl basket to the outside of the receiving cavity through the first opening, the irradiation range of the lighting device on the bowl basket is relatively large, which is convenient for the user to operate.

[0038] In a second aspect, an embodiment of the present application provides a dishwasher, including:

[0039] A cabinet, the cabinet is constructed with a receiving cavity;

[0040] A bowl basket, the bowl basket is located in the receiving cavity and is slidably connected to the cabinet;

[0041] A lighting device, the lighting device is located at the top of the receiving cavity, the lighting device is close to one end of the cabinet in the width direction, and the main optical axis of the lighting device has a second included angle with the ground, and the second included angle is not equal to 90 degrees.

[0042] Based on the principle that the farther away from the lighting device along the direction of the main optical axis, the larger the illumination range of the lighting device, in this application, the lighting device is arranged at the top of the box body, near one end of the box body along the width direction. The main optical axis of the lighting device has a second included angle with the ground, and the second included angle is not equal to 90 degrees. Thus, the distance from the inner wall of the box body to the lighting device along the direction of the main optical axis can be changed, and the illumination range of the lighting device can be changed. Therefore, the inside of the box body can be illuminated by using one lighting device, reducing the number of lighting devices, and thus the cost can be reduced. Description of the Drawings

Detailed implementation manners

[0061] Figure 1 Schematic diagram of the structure of the inner container and the lighting device in the dishwasher in the related art.

[0062] See Figure 1 As shown, the dishwasher includes an inner container 110, and a lighting device 300 is arranged inside the cabinet. Since the main optical axis of the lighting device 300 is perpendicular to the ground, that is to say, the light of the lighting device 300 is straight up and down, usually two lighting devices 300 need to be arranged on the left and right in the width direction to illuminate the inside. The cost of the two lighting devices 300 is relatively high.

[0063] In order to solve the above technical problems, based on the principle that the farther the distance from the lighting device along the direction of the main optical axis, the larger the illumination range of the lighting device, in the present application, the lighting device is arranged at the top of the cabinet, close to one end of the cabinet in the width direction, and the main optical axis of the lighting device forms a second angle with the ground, and the second angle is not equal to 90 degrees, so as to change the distance from the inner wall of the cabinet to the lighting device along the direction of the main optical axis, change the illumination range of the lighting device, so that the inside of the cabinet can be illuminated by using one lighting device, reducing the number of lighting devices, and thus reducing the cost.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0071] An embodiment of the present application provides a dishwasher, which can be an embedded dishwasher or a freestanding dishwasher.

[0072] Figure 2 It is a schematic structural diagram of the dishwasher provided in the embodiment of the present application. Figure 3 It is a schematic structural diagram of the inner liner and the lighting device in the dishwasher provided in the embodiment of the present application.

[0073] See Figure 2 and Figure 3 As shown, in some embodiments, the dishwasher includes a cabinet 100.

[0074] Among them, the cabinet 100 is configured with a receiving cavity. One side of the cabinet 100 in the depth direction is configured with a first opening, and the first opening communicates with the receiving cavity. The side where the first opening is configured is the front side.

[0075] Among them, the depth direction is the direction shown by the Y-axis in the figure.

[0076] In some embodiments, the dishwasher includes a door body 200, and the door body 200 is rotatably connected to the cabinet 100 to open or close the first opening.

[0077] Specifically, an operation handle is provided on the door body 200.

[0078] In some embodiments, the dishwasher includes a bowl basket (not shown in the figure). The bowl basket is used for placing tableware.

[0079] Among them, the bowl basket is located in the receiving cavity and is slidably connected to the cabinet 100. The bowl basket slides relative to the cabinet 100, so that it can enter and exit the receiving cavity through the first opening.

[0080] Figure 4 It is Figure 3 a partial enlarged view of the A position in Figure 5 It is a light ray schematic diagram of the lighting device in the dishwasher provided in the embodiment of the present application. Figure 6 It is a top view of the inner liner and the lighting device in the dishwasher provided in the embodiment of the present application. Figure 7 It is Figure 6 a partial enlarged view of the B position in

[0081] See Figures 3 to 7As shown, in some embodiments, the dishwasher includes a lighting device 300. The lighting device 300 is used to illuminate the accommodation cavity.

[0082] In some embodiments, the lighting device 300 is connected to the cabinet 100, and the lighting device 300 is located inside the cabinet 100 and near the top of the cabinet 100.

[0083] Specifically, the lighting device 300 is located at the top of the accommodation cavity.

[0084] It should be noted that the lighting device 300 can be located inside the accommodation cavity. Or, the lighting device 300 can be located outside the accommodation cavity, and the lighting device 300 irradiates the accommodation cavity through an opening communicating with the accommodation cavity.

[0085] In some embodiments, the lighting device 300 is near one end of the cabinet 100 in the width direction. The width direction is the direction shown by the X-axis in the figure.

[0086] It should be noted that the two ends of the cabinet 100 in the width direction are respectively the first end and the second end. The distance from the lighting device 300 to the first end is not equal to the distance from the lighting device 300 to the second end. Among them, the distance from the lighting device 300 to the first end can be greater than the distance from the lighting device 300 to the second end. The light-emitting surface of the lighting device 300 is inclined towards the first end. Or, the distance from the lighting device 300 to the first end can be less than the distance from the lighting device 300 to the second end. The light-emitting surface of the lighting device 300 is inclined towards the second end.

[0087] In some embodiments, the lighting device 300 is near the first opening.

[0088] It can be understood that when the user pulls the bowl basket out of the cabinet 100, due to the weak external ambient light or the user blocking the ambient light, the lighting device 300 is required to illuminate the external bowl basket. The lighting device 300 is near the first opening, which can increase the range of irradiation to the external bowl basket, thus facilitating the user to pick up and place tableware in the bowl basket.

[0089] Specifically, the lighting device 300 is near the edge of the cabinet 100 in the depth direction and near the first opening. Among them, the depth direction is the direction shown by the Y-axis.

[0090] See Figure 5 As shown, the main optical axis a of the lighting device 300 has a second included angle d with the ground, and the second included angle d is not equal to 90 degrees.

[0091] It should be noted that the main optical axis a of the lighting device 300 is a virtual line, and the light beam of the lighting device 300 is symmetrical about the main optical axis a. The light beam of the lighting device 300 is an orthographic projection of a plane formed in the direction indicated by the X-axis and the Z-axis, and the first boundary line b and the second boundary line c of the light beam are symmetrical about the main optical axis a. The angle between the first boundary line b and the second boundary line c of the light beam is the light-emitting angle of the lighting device 300.

[0092] See also Figure 2 and Figure 3 As shown, in some embodiments, the box 100 includes a shell. The shell can play a role of protection and aesthetics.

[0093] The housing is configured with an inner cavity.

[0094] In some embodiments, the box 100 includes an inner liner 110 .

[0095] The inner liner 110 is located in the outer shell, and the inner liner 110 is configured with a receiving cavity. A first opening is configured on one side of the inner liner 110 along the depth direction, and the first opening is communicated with the receiving cavity.

[0096] In some embodiments, the top of the liner 110 is configured with a second opening, and the second opening is connected to the accommodating cavity. The lighting device 300 may be located outside the accommodating cavity, and the lighting device 300 illuminates the accommodating cavity through the second opening connected to the accommodating cavity.

[0097] In some embodiments, the second opening is adjacent to the edge of the inner container 110 along the depth direction and is close to the first opening.

[0098] In some embodiments, the box 100 is configured with a mounting surface, and the extended plane of the mounting surface has a first angle with the ground. The end of the lighting device 300 that is away from the light emitting surface abuts against the mounting surface. In other words, there is no need to modify the internal structure of the lighting device 300, and the lighting device 300 only needs to be installed at an angle, so that the main optical axis a of the lighting device 300 has a second angle d with the ground, and the second angle d is not equal to 90 degrees.

[0099] In some embodiments, the lighting device 300 includes a lamp holder 310 .

[0100] The lamp holder 310 may be connected to the box body 100 . Specifically, the lamp holder 310 may be connected to the outer wall of the inner container 110 .

[0101] In some embodiments, the lamp holder 310 is configured with a mounting cavity 311 , and the mounting cavity 311 is used to provide a mounting space for the light source structure.

[0102] In some embodiments, the bottom wall of the mounting cavity 311 is configured with a lens structure 320. The lens structure 320 can diverge or gather the light of the light source structure.

[0103] In some embodiments, the lighting device 300 is connected to the outer top wall of the inner container 110, and the lens structure 320 faces the second opening.

[0104] In some embodiments, the lighting device 300 includes a light source structure 330. The light source structure 330 is configured to emit light.

[0105] In some embodiments, the light source structure 330 includes a circuit board 331.

[0106] Wherein, the circuit board 331 is located in the installation cavity 311, and the extension plane of the circuit board 331 has a first included angle e with the ground.

[0107] In some embodiments, the light source structure 330 includes lamp beads 332. The lamp beads 332 are connected to the circuit board 331 and face the lens structure 320.

[0108] It can be understood that, based on the principle that the farther away from the lighting device 300 along the direction of the main optical axis, the larger the illumination range of the lighting device 300, in the present application, the lighting device 300 is arranged at the top of the box body 100, the lighting device 300 is close to one end of the box body 100 along the width direction. The lighting device 300 is provided with a lamp holder 310 and a light source structure 330. The circuit board 331 of the light source structure 330 is located in the installation cavity 311 of the lamp holder 310. The extension plane of the circuit board 331 has a first included angle e with the ground. The lamp beads 332 of the light source structure 330 are connected to the circuit board 331, and the lamp beads 332 face the lens structure 320 at the bottom wall of the lamp holder 310, so that the main optical axis of the lighting device 300 has a second included angle d with the ground, and the second included angle d is not equal to 90 degrees. Thus, the distance from the inner wall of the box body 100 to the lighting device 300 along the direction of the main optical axis can be changed, and the illumination range of the lighting device 300 can be changed. Therefore, the inside of the box body 100 can be illuminated by one lighting device 300, the number of lighting devices 300 is reduced, and the cost can be reduced.

[0109] In some embodiments, the sum of half of the light emitting angle of the lighting device 300 and the first included angle e is 90 degrees.

[0110] In some embodiments, the light emitting angle of the lighting device 300 is 120 degrees to 140 degrees.

[0111] In some embodiments, the light emitting angle of the lighting device 300 is 120, and the first included angle e is 40 degrees. The light emitting angle of the lighting device 300 is 130, and the first included angle e is 35 degrees. The light emitting angle of the lighting device 300 is 140, and the first included angle e is 30 degrees.

[0112] It should be noted that the main optical axis a of the lighting device 300 is a virtual line, and the light beam of the lighting device 300 is symmetric about the main optical axis a. The positive projection of the light beam of the lighting device 300 onto the plane formed by the directions shown by the X-axis and the Z-axis, the first boundary line b and the second boundary line c of the light beam are symmetric about the main optical axis a. The included angle between the first boundary line b and the second boundary line c of the light beam is the light-emitting angle of the lighting device 300. That is to say, half of the light-emitting angle of the lighting device 300 is the included angle between the main optical axis a of the lighting device 300 and the first boundary line b of the light beam. Alternatively, half of the light-emitting angle of the lighting device 300 is the included angle between the main optical axis a of the lighting device 300 and the second boundary line c of the light beam.

[0113] Among them, the first included angle e is the included angle less than 90 degrees between the extending plane of the circuit board 331 and the ground.

[0114] In some embodiments, the first included angle e is from 30 degrees to 40 degrees.

[0115] Among them, the first included angle e is greater than 30 degrees and less than 40 degrees.

[0116] Exemplarily, the first included angle e can be 35 degrees, or 38 degrees.

[0117] It can be understood that when the height of the accommodation cavity is fixed and the light-emitting angle of the lighting device 300 is fixed, when the lighting device 300 is close to the first end of the box body 100 in the width direction, the first included angle e is less than 30 degrees, the inclination angle is small, and the brightness of the bottom area of the second end of the box body 100 in the width direction is small. When the first included angle e is greater than 40 degrees, the inclination angle is large, and the brightness of the bottom area of the first end of the box body 100 in the width direction is small.

[0118] When the height of the accommodation cavity is fixed and the light-emitting angle of the lighting device 300 is fixed, when the lighting device 300 is close to the second end of the box body 100 in the width direction, the first included angle e is less than 30 degrees, the inclination angle is small, and the brightness of the bottom area of the first end of the box body 100 in the width direction is small. When the first included angle e is greater than 40 degrees, the inclination angle is large, and the brightness of the bottom area of the second end of the box body 100 in the width direction is small.

[0119] Figure 8 It is a schematic structural diagram of the lighting device in the dishwasher provided by the embodiment of the present application. Figure 9 It is a top view of the lighting device in the dishwasher provided by the embodiment of the present application. Figure 10 is Figure 9 the cross-sectional view along the C-C direction in Figure 11 It is a schematic structural diagram of the base in the dishwasher provided by the embodiment of the present application.

[0120] See Figures 8 to 11As shown, in some embodiments, in order to facilitate the installation of the circuit board 331, a guiding inclined surface 340 that abuts against the circuit board 331 is formed on the bottom wall of the installation cavity 311.

[0121] Among them, the extended plane of the guiding inclined surface 340 has a first included angle e with the ground.

[0122] Among them, one side of the circuit board 331 facing the lamp beads 332 abuts against the guiding inclined surface 340. In this way, when installing the light source structure 330, it is only necessary to place the side of the circuit board 331 facing the lamp beads 332 on the guiding inclined surface 340. The installation is relatively simple and the installation efficiency is relatively high.

[0123] In some embodiments, the circuit board 331 can be bonded to the guiding inclined surface 340.

[0124] Figure 12 It is a schematic structural diagram of the light source structure in the dishwasher provided by the embodiment of the present application.

[0125] See Figure 12 As shown, in some embodiments, in order to limit the installation position of the light source structure 330, the circuit board 331 is configured with a first positioning portion 3311.

[0126] See Figure 11 As shown, a second positioning portion 341 is formed on the guiding inclined surface 340. The second positioning portion 341 matches the first positioning portion 3311, and the second positioning portion 341 is connected to the first positioning portion 3311.

[0127] See Figures 10 to 12 As shown, in some embodiments, the first positioning portion 3311 includes at least one positioning cavity, and the second positioning portion 341 includes at least one positioning protrusion. The at least one positioning cavity and the at least one positioning cavity are arranged in one-to-one correspondence, and the positioning protrusion is inserted into the corresponding positioning cavity.

[0128] In some embodiments, for the convenience of processing, the first positioning portion 3311 includes at least one positioning protrusion, and the second positioning portion 341 includes at least one positioning cavity. The at least one positioning protrusion and the at least one positioning cavity are arranged in one-to-one correspondence, and the positioning protrusion is inserted into the corresponding positioning cavity.

[0129] It can be understood that, compared with adding positioning protrusions to the circuit board 331, the processing difficulty of setting the positioning cavity by means of punching and removing materials is relatively small.

[0130] In some embodiments, the first positioning portion 3311 includes at least two spaced positioning protrusions, and the second positioning portion 341 includes at least two spaced positioning cavities. The at least two positioning protrusions and the at least two positioning cavities are arranged in one-to-one correspondence, and the positioning protrusion is inserted into the corresponding positioning cavity.

[0131] In some embodiments, at least two positioning protrusions are disposed on opposite sides of the guiding inclined surface 340. For example, two positioning protrusions are disposed on opposite sides of the guiding inclined surface 340 along the direction shown by the X-axis. In this way, the position of the light source structure 330 along the directions shown by the X-axis and the Y-axis can be restricted.

[0132] In some embodiments, the lamp socket 310 includes a base 350.

[0133] Wherein, a lens structure 320 is formed on the bottom wall of the base 350, and the lens structure 320 is integrally provided with the base 350. In this way, it can be integrally formed by injection molding, and the processing efficiency is relatively high.

[0134] It can be understood that the lens structure 320 and the base 350 can be integrally formed by injection molding. The material of the base 350 can be transparent resin or plastic.

[0135] In some embodiments, the guiding inclined surface 340, the second positioning portion 341, the lens structure 320 and the base 350 are integrally provided.

[0136] In some embodiments, the lamp beads 332 are surface mount lamp beads.

[0137] It can be understood that the surface mount lamp beads have a relatively small volume and occupy a relatively small space. Moreover, the cost of the surface mount lamp beads is relatively low.

[0138] In some embodiments, the lens structure 320 is a convex lens structure. The convex lens structure can play a role in concentrating light.

[0139] It can be understood that the surface mount lamp beads have a relatively large light emitting angle, and the light is concentrated by the convex lens structure, which is beneficial to improving the brightness of the light.

[0140] The lamp beads 332 are located on the side of the lens structure 320 facing the circuit board 331. The lamp beads 332 are on the main optical axis of the lens structure 320, and the position of the lamp beads 332 is in front of the focal point of the lens structure 320. In this way, the light emitted by the lamp beads 332 with a relatively large light scattering angle can be concentrated by the lens structure 320 more. After being refracted and concentrated by the lens structure 320, the light scattering angle is reduced, and the concentrated light is still in a state symmetrical to the main optical axis.

[0141] See Figure 11 As shown, the base 350 is formed with a wire harness structure, and the wire harness structure is formed with a limiting cavity.

[0142] See Figure 12 As shown, the light source structure 330 further includes a wire harness 333, and the wire harness 333 is electrically connected to the circuit board 331. Part of the wire harness 333 is disposed in the limiting cavity, and part of the wire harness 333 extends to the outside of the lamp socket 310 after passing through the limiting cavity.

[0143] Figure 13 Schematic diagram of the structure of the upper cover plate in the dishwasher provided by the embodiment of the present application.

[0144] See Figure 11 and Figure 13 In some embodiments, the lamp holder 310 includes a cover plate 360.

[0145] The cover plate 360 is disposed on the top of the base 350, and the cover plate 360 is detachably connected to the base 350.

[0146] Specifically, a plurality of first buckles 370 are spaced apart on the peripheral side of the cover plate 360. A plurality of second buckles 380 are spaced apart on the peripheral side of the base 350. The first buckles 370 and the second buckles 380 are arranged in one-to-one correspondence, and the first buckles 370 are snap-connected to the second buckles 380.

[0147] See Figure 10 and Figure 13 As shown in

[0148] It can be understood that the limiting portion 390 may be a limiting protrusion, for example, a limiting post.

[0149] The installation process of the lighting device 300 will be introduced below.

[0150] During assembly, the circuit board 331 of the light source structure 330 is placed on the guiding inclined surface 340 of the base 350. Through the cooperation of the positioning cavity and the positioning protrusion, the position of the circuit board 331 placed obliquely is ensured (the positions in the directions shown by the Y-axis and the X-axis are restricted). Then, the cover plate 360 is installed on the base 350 with the light source structure 330 by snap-connecting the first buckle 370 and the second buckle 380. After the cover plate 360 is connected to the base 350, the limiting portion 390 abuts against the circuit board 331, thereby restricting the position of the circuit board 331 in the direction shown by the Z-axis.

[0151] It can be understood that adhesives and fasteners are not required for connection during assembly, and the installation efficiency is relatively high. Moreover, it is convenient to maintain the lighting device 300 subsequently, for example, to replace the light source structure 330.
