Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to a prompt lighting device and a household appliance. Background Art

[0002] A dishwasher is a device that automatically washes tableware such as bowls, chopsticks, plates, dishes, knives, and forks. The working process of a dishwasher can be divided into the following main steps: water intake, softening, spraying, cycle washing, draining, and drying.

[0003] Water inlet process: When the dishwasher is started and begins to take in water, the water inlet valve opens automatically, and tap water enters the breather through the water inlet pipe to prevent water backflow. Softening process: The water is softened by the water softener. The regenerated resin in the softener can remove calcium and magnesium ions in the water to prevent scale formation. The softened water in the spraying process enters the washing motor through the drain tank, generating pressure, and transporting the water to the spray arm to spray it out to clean the tableware. Circulating washing process: The dishwasher uses water in stages. First, clean water is used to remove food residues, and then clean water with detergents to clean oil stains, and finally rinse the residue with clean water. Drainage process: After the circulating washing process is completed, the drain pump generates pressure to discharge the sewage. Drying process: After the spray water is drained, the tableware is dried through heat exchange to achieve high-temperature disinfection and ensure that the tableware is clean and sterile.

[0004] In each of the above operating states, the user can observe the dishwasher's operating process through the window to promptly understand the current operating status. However, to improve the accuracy of the operating status judgment, the prior art generally provides a prompting spotlight that uses different colors of light or projects different prompting patterns to inform the user of the dishwasher's operating status.

[0050] Embodiment one

[0051] Figure 1 is a schematic view of the prompt lighting device provided by the embodiment one of the present application; Figure 2 is a partial structure bottom view of the prompt lighting device provided by the embodiment one of the present application; Figure 3 is a schematic view of the prompt lighting device installed outside the door body provided by the embodiment one of the present application. With reference to Figure 1-Figure 3 , the present embodiment provides a prompt lighting device and a household appliance. The household appliance can be specifically a washing machine, a clothes dryer or a dishwasher and the like having multiple working states. In the present embodiment, the household appliance is taken as a dishwasher for example for illustration.

[0052] Specifically, the dishwasher includes a machine body 20, a door body 10 and the prompt lighting device provided by the present embodiment. The machine body 20 can perform water inlet process, softening process, spraying process, circulating washing process, drainage process and drying process. The door body 10 is arranged at the opening of the machine body 20 and can seal or open the opening of the machine body 20. The prompt lighting device is installed on the side of the door body 10 away from the machine body 20 and can project a light spot onto the ground below the door body 10 to remind the user of the working program being performed in the machine body 20 at the moment.

[0053] With reference to Figure 1 and Figure 2 , the prompt lighting device provided by the present embodiment includes a projection light source 100 and a light blocking piece 200. The projection light source 100 has multiple projection colors, and each projection color corresponds to a working state of the dishwasher. For example, yellow light corresponds to water inlet process, green light corresponds to softening process, blue light corresponds to spraying process, white light corresponds to circulating washing process, orange light corresponds to drainage process, red light corresponds to drying process and the like. It should be noted that the projection color corresponding to each process can be selected according to actual needs, and the present embodiment does not limit the specific projection color corresponding to each process.

[0054] Specifically, the light blocking member 200 is a disk-shaped structure, on which a plurality of non-identical lenses 210 are arranged. The light blocking member 200 can be rotated or moved to move the plurality of non-identical lenses 210 in sequence to the light output path of the projection light source 100. In this embodiment, the light blocking member 200 is rotated to drive the movement of the lens 210 for explanation. The size of the light spot formed by the projection light source 100 through different lenses 210 and / or the light intensity of the light spot are different. In this embodiment, a plurality of lenses 210 are arranged in a circular array on the light blocking member 200, a part of the plurality of lenses 210 are focusing lenses, and the other part are diffusion lenses. The focusing lens can reduce the size of the projected light spot, concentrate the light and thus make the light intensity of the light spot greater, and the diffusion lens can amplify the projected light spot, diverge the light and thus weaken the light intensity of the light spot. It should be noted that the appropriate lens 210 can be selected by focal length to have the effect of focusing the light spot or diffusing the light spot. That is to say, by setting a plurality of different lenses 210, the projected light spots can change in size and intensity during the rotation of the light blocking member 200, forming a state similar to "breathing".

[0055] More specifically, in order to enhance the flickering effect of the light spot, in this embodiment, the focusing lens and the diffusion lens should be arranged at intervals in the circumferential direction of the light blocking member 200 .

[0056] More specifically, the prompt lighting device further includes a drive assembly 300, the output shaft of which is connected to the light blocking member 200 and is capable of driving the light blocking member 200 to rotate. In this embodiment, the drive assembly 300 can be specifically selected from a motor, etc., so long as it can drive the light blocking member 200 to rotate. The specific type of the drive assembly 300 is not limited in this embodiment.

[0057] Continue to refer to Figure 1-Figure 3 The prompt lighting device further includes a housing 400, which specifically includes a shell. The projection light source 100, the light blocking member 200, and the driving assembly 300 are respectively disposed within the shell. The shell can protect the internal components thereof and prevent the internal components from being damaged by water.

[0058] Specifically, a light outlet 410 is provided at the bottom of the housing, facing the projection light source 100. The rotation of the light blocking member 200 drives the multiple lenses 210 to move sequentially between the projection light source 100 and the light outlet 410. Light from the projection light source 100 can sequentially pass through the lenses 210 and the light outlet 410 facing it, and then form a light spot on the ground.

[0059] It should be noted that in order to ensure the sealing of the housing 400 and achieve the light transmission effect of the light outlet 410, in this embodiment, a sealing plate of a transparent material is provided at the light outlet 410. The sealing plate can be made of flat acrylic or flat glass.

[0060] More specifically, the housing 400 also includes a partition member 420, which is arranged in the housing and has a plate-like structure, and can divide the space in the housing into a first space 430 and a second space 440. The projection light source 100 is located in the first space 430, and a portion of the light blocking member 200 can pass through the partition member 420 and extend into the first space 430. The inner wall of the first space 430 is provided with a reflective layer, and the light outlet 410 is opened in the first space 430. During the rotation of the light blocking member 200, multiple lenses 210 can enter the first space 430 in sequence. It should be noted that the height of the through groove is greater than the thickness of the light blocking member 200, so as to avoid it hindering the rotation of the light blocking member 200. Through the above arrangement, the light can be concentrated in the first space 430, and under the action of the reflective layer provided on the inner wall of the first space 430, it can be concentrated and emitted from the light outlet 410, thereby improving the efficiency of the light.

[0061] Example 2

[0062] This embodiment provides a prompt lighting device.

[0063] Figure 4 This is a schematic diagram of the prompt lighting device provided by the second embodiment of the present utility model. Figure 4 The difference between this embodiment and the first embodiment is that the housing 400 of the prompt lighting device provided in this embodiment does not have a partition member 420 but is provided with a light emitting sleeve 450 .

[0064] Specifically, the light-emitting sleeve 450 is disposed within the housing, and the projection light source 100 and the light-emitting port 410 are coaxially disposed within the light-emitting sleeve 450. The light-blocking member 200 rotates to allow the multiple lenses 210 to sequentially enter the light-emitting sleeve 450 within the projection range of the light-emitting port 410. The inner wall of the light-emitting sleeve 450 is provided with a reflective layer. By providing the light-emitting sleeve 450, the light emission path of the projection light source 100 can be further limited to passing through the lens 210 directly opposite it, thereby avoiding energy loss due to light scattering, which affects the brightness of the light spot.

[0065] Example 3

[0066] This embodiment provides a prompt lighting device.

[0067] Figure 5 This is a schematic diagram of a prompt lighting device provided in the third embodiment of the present utility model; Figure 6 This is a top view of a partial structure of the prompt lighting device provided in the third embodiment of the present invention. Figure 5 and Figure 6 The difference between this embodiment and the first embodiment is that the prompt lighting device provided in this embodiment further includes a light blocking support member 500 .

[0068] Specifically, the light shielding support member 500 is disposed in the second space 440 in the housing and is connected to the side of the partition member 420 facing away from the first space 430. The light shielding support member 500 can be supported below the light shielding member 200 to ensure the stability and reliability of the rotation process of the light shielding member 200.

[0069] More specifically, the light-shielding support member 500 is an annular structure, with both ends connected to the partition member 420, and the annular radius is equal to the radius of the light-shielding member 200. In other words, the light-shielding support member 500 can be partially supported below the light-shielding member 200 along the circumferential direction, thereby providing reliable support for the light-shielding member 200 and avoiding the output shaft of the drive assembly 300.

[0070] More specifically, a ball bearing 510 is movably disposed on the light-blocking support member 500, and the ball bearing 510 is supported below the light-blocking member 200. In this embodiment, an annular groove is formed along the circumference of the light-blocking support member 500, and a plurality of ball bearings 510 are disposed in the annular groove. The provision of the ball bearings 510 can reduce friction between the light-blocking support member 500 and the light-blocking member 200, thereby reducing the resistance of the light-blocking support member 500 to the rotation of the light-blocking member 200 and improving the smoothness of the rotation of the light-blocking member 200.

[0071] Example 4

[0072] This embodiment provides a prompt lighting device.

[0073] Figure 7 This is a top view of a partial structure of the prompt lighting device provided by the fourth embodiment of the present utility model. Figure 7 The difference between this embodiment and the third embodiment lies only in the specific structure of the light-blocking support member 500.

[0074] Specifically, the light-blocking support member 500 specifically includes a plurality of support portions 520 arranged in a circular array. In the present embodiment, there are three support portions 520. The two support portions 520 at both ends are respectively connected to the partition member 420, and the support portion 520 in the middle is connected to the inner wall of the shell facing the partition member 420 through a connecting rod 521. In order to enhance its supporting effect, a support rod can be provided below the support portion 520, and the support rod is specifically connected to the inner bottom of the shell. Through the above arrangement, the material used for the light-blocking support member 500 can be reduced while ensuring the supporting performance, thereby reducing its space occupation within the shell.

[0075] Example 5

[0076] This embodiment provides a prompt lighting device and a household appliance. In this embodiment, the household appliance is also a dishwasher.

[0077] Figure 8 This is a schematic diagram of the fifth embodiment of the present invention, wherein the warning lighting device is installed within the door. This embodiment differs from the first embodiment in that the warning lighting device is installed within the door 10, and the light outlet 410 is flush with the bottom edge of the door 10. This arrangement reduces the space occupied by the dishwasher and improves its integration.

[0078] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention.
